Module: XML Sitemap

Recommended Posts

I'm on the verge of converting your code back to a template, this is getting silly...

Just want to clarify that the problem is not with Pete's module. There was an obscure problem with the modules installer in the core which has been fixed. I'm not certain this is the problem in your case as you are still getting a different behavior than us, but I suggest grabbing the latest copy of ProcessWire before trying anything else.

Just want to clarify that the problem is not with Pete's module.

My apologies for implying any such thing, just getting frustrated. When I saw this module it looked like a great timesaver, and that hasn't worked out.

I'm uploading a fresh copy of PW now, we'll see how it goes.

EDIT: Still no go!

Can you confirm that you still get this same error message and that your ProcessWire reports it's version number as 2.2?

Exception: Unable to create path: /MarkupSitemapXML/ (in /home/theseeke/public_html/wire/core/CacheFile.php line 62) This error message was shown because you are logged in as a Superuser. Error has been logged.

I just downloaded a fresh/blank copy of PW 2.2 and installed this module just to make sure it didn't have anything to do with the dev site I had tested on before. But it's working as expected, creating the dir in the right place, etc. So there must be something else that I'm missing. The behavior you are describing definitely indicates a core bug. I can't think of any other possibility. I'm going to do more testing here and hope to find and push a solution shortly.

I'm pleased to say that this issue is resolved, and when it came right down to it, Problem Existed Between Keyboard and Chair.

Stupid me forgot to read the instructions, and installed the module to /wire/modules instead of /site/modules.

Now that it's in the right place it's working fine, cheers!

Thanks for reporting back, glad that it's working. I was stuck trying to determine how it was doing that, so it's a relief to hear it's resolved. This has still been valuable though as we did solve a bug as a result (top of this page).

Hi there,

I've been using this module on a couple of sites in place of the template I previously used and it certainly is a boon in keeping my template folder a lot tidier — great work!

I changed line 53 to check for access when iterating the children so that user-restricted pages do not show up in the sitemap. I think this is a saner default but could be a settting too.

foreach($page->children("check_access=1") as $child) $entry .= $this->sitemapListPage($child);

Stephen: check_access=1 is default, so you don't have to include that. If you don't want to check access, then you need to use check_access=0.

Very true. I obviously visited the sitemap straight after installing, while still logged in as admin. My mistake!

Want to share a few things I've added for a magazine site I'm building:

First of all, I think "priority" and "changefreq" are fairly important if you're going to have a sitemap at all. This post has some info on Google's guidelines: http://www.eduki.com...-are-important/

What I decided to do was quickly add two global fields to PW so I can set these values manually in each page:



And in the code:

public function sitemapListPage($page) {
$entry = "";
$default_priority = "0.5";
$default_changefreq = "monthly";

include $this->fuel('config')->paths->templates . "sitemap_module_defaults.inc";

if ($page->sitemap_ignore == 0 || $page->path == '/') { // $page->path part added so that it ignores hiding the homepage, else you wouldn't have ANY pages returned
$modified = date ('Y-m-d', $page->modified);
$entry = "\n <url>\n";
$entry .= " <loc>{$page->httpUrl}</loc>\n";
$entry .= " <lastmod>{$modified}</lastmod>\n";

if(!empty($page->sitemap_priority)) {
$entry .= " <priority>{$page->sitemap_priority}</priority>\n";
} else {
$entry .= " <priority>{$default_priority}</priority>\n";

if(!empty($page->changefreq)) {
$entry .= " <changefreq>{$page->changefreq}</changefreq>\n";
} else {
$entry .= " <changefreq>{$default_changefreq}</changefreq>\n";

 $entry .= " </url>";
if($page->numChildren) {
foreach($page->children as $child) $entry .= $this->sitemapListPage($child);
return $entry;

The sitemap_module_defaults.inc file in the templates dir is so I can set some values on the fly without doing it manually:

switch($page->template->name) {
case "blog_post":
case "blog_topic":
case "blog_topic_type":
$default_priority = "0.7";
$default_changefreq = "daily";

That's done and works fine for me.

Something I found frustrating with the sitemap module was that I couldn't add virtual pages I made. For example, if there's a page with urlSegments with some kind of page manipulation they won't show up on the sitemap, for obvious reasons. So what I did was add this method to the module:

public function sitemapListVirtualPage($httpUrl, $modified = NULL, $sitemap_priority = "0.5", $changefreq = "monthly") {
$entry = "";
$modified = date ('Y-m-d', $modified);
$entry = "\n <url>\n";
$entry .= " <loc>{$httpUrl}</loc>\n";

if($modified) {
$entry .= " <lastmod>{$modified}</lastmod>\n";

if($sitemap_priority) {
$entry .= " <priority>" . (float)$sitemap_priority . "</priority>\n";

if($changefreq) {
$entry .= " <changefreq>{$changefreq}</changefreq>\n";

 $entry .= " </url>";
return $entry;

And added this include to the init method before the output is saved to cache:

public function init() {
// Intercept a request for a root URL ending in sitemap.xml and output
if (strpos($_SERVER['REQUEST_URI'], wire('config')->urls->root . 'sitemap.xml') !== FALSE) {
// Check for the cached sitemap, else generate and cache a fresh sitemap
$cache = wire('modules')->get("MarkupCache");
if(!$output = $cache->get("MarkupSitemapXML", 3600)) {
$output = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n";
$output .= '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">';
$output .= $this->sitemapListPage(wire('pages')->get("/"));

include $this->fuel('config')->paths->templates . "sitemap_module_virtual.inc";

$output .= "\n</urlset>";

header("Content-Type: text/xml");
echo $output;

And in my sitemap_module_virtual.inc file I did this:

foreach(wire('pages')->find("template=blog_topic|blog_topic_type") as $real_page) {
$output .= $this->sitemapListVirtualPage("http://" . $this->fuel('config')->httpHost . $real_page->url . "archives/", wire('pages')->get("template=blog_post,sort=-created")->modified, "0.4", "daily");
foreach(wire('pages')->find("template=blog_topic|blog_topic_type") as $real_page) {
$output .= $this->sitemapListVirtualPage("http://" . $this->fuel('config')->httpHost . $real_page->url . "rss/", wire('pages')->get("template=blog_post,sort=-created")->modified, "0.4", "daily");

In this part, I have manipulated /archive/ and /rss/ sub-pages for each blog_topic and sub-topic(or blog_topic_type) using urlSegments. I wanted these to show up on the sitemap, even though they're probably not super important.

Usually I wouldn't bother doing this if it was just these kinds of pages. But what if you have countless articles with manipulated urls that don't show in the sitemap? This is perfect example of why I did this for the future as well.

I've been trying to understand how to do these things for a while, so I hope it helps someone out.

EDIT: I have a download with all of my changes if anyone's interested in taking a look: http://clintonskakun.com/processwire-docs/posts/the-xml-sitemap-module-with-priority-and-changefreq-and-more/

Thanks for posting this, these seem like some useful additions and some good insights on sitemap.xml too.

jukooz asked me a while back how to stick the sitemaps into a template as he's using the multisite module and currently I guess that this module will pull the sitemap for EVERY site on an install...?

This should work on a per-site basis having it in a separate template file per site as a workaround for now, but pay attention to the comments please as there are things to change per-site - please also note that this is un-tested and largely just pulled from the module and tweaked for pasting into a template for use instead of the module:

EDIT: See attachment as the forum software tries to parse a URL in the code : sitemap.txt

I've also updated the module (see first post) to v1.0.3 to check if the page is viewable before including it in the sitemap - I noticed that it was incorrectly listing pages that had no template file... oops!

is it possible to use this module with the LanguageLocalizedURL ?

I wanne make the site multilanguage like this:



Would like to hear from you... Greets Jens alias DV-JF

While I've not tried it, I would guess that this module does not collaborate with or accommodate the LanguageLocalizedURL module in any special way. Though Pete could say for sure.

It doesn't accommodate it at the moment, no, but I may need this myself soon so if you can wait a week or two I may have an update (it's not at the top of my list at the moment but I might surprise myself and do it sooner ;)).

Thinking out loud, it needs:

  • Check if LanguageLocalizedURL is installed
  • Find the root page for each language
  • Generate a sitemap.xml page under each root page (it doesn't really generate a page in the database, it just outputs the sitemap if you request that URL)

I think that's it, but I need to get to grips with the LanguageLocalizedURL first.

Pete the LLU module doesn't have separate trees, it uses a gateways page for each language in the root like "/de/" "/en/" with url segments to then get the page and switch user language.  The site structure is still all the same as without, you just use text language fields.

The parsing of the url happend automaticly through these gateway pages and it hooks into Page::path to change the url of the pages system wide. So if you do a echo $page->url you'll get the language url in the language you're currently in. Like /en/about-us/, /de/ueber-uns/. 

Have anyone tried yet if it doesn't already work?

Soma just submitted a pull request and I merged it.

The 1.0.4 version should allow you to use this with the LanguageLocalizedURL module - let us know how you get on and thanks to Soma ;)

Pete, thanks, but I already pulled another request, forgot to up the cache time.

Also to fully work it would also have to add the "language_published" check to see if language version of the page is really published. Will try to add that later.

Also wanted to add that I never use sitemaps for google and never will again (used to try long time ago, but it doesn't really help at all if you build the site carefully. It just eating time doing it and making sure everthing works still). It's not as easy as it first seems and can even be contra productive if not done carefully. Problem with this module as it is now, it will not find and list pages that may are added through urlSegments and I don't see a way to do it easy. Also it doesn't have weighting etc.

Thanks - merged it :)

The main reason I created it was because it gets a new site listed faster - plain and simple. That was my experience from sitemaps a few years ago at least so I hope it still happens, but it does seem to work from my experience.

I've never bothered with weighting or anything like that. Not bothered about URL segments either as for a start the crawler will find a link to that from a normal page on the site presumably, but my main goal was to get Google to crawl the page sooner than it normally would - and I think it will do this every time it looks at the sitemap and sees a new page (assuming it doesn't find it in the crawl already on its own by following links in the content).

Think of it this way - if you release a brand new site without telling Google, it will take until someone links to your site before Google is aware of its existence. On a small, personal site with no blog or comments that could be a loooong time, but the first thing I usually do is launch a site and submit it so I know it's done.

The argument against this is there are other ways of doing that as search engine companies often have pages where you can just type your domain in and they will search it sometime later, but I like to keep Google informed when I add new pages etc just in case it has a lapse in concentration and misses something :)

just uped another pull request... :)

I think google doesn't parse the website if it has a sitemap.xml. Or has this changed? I found myself fixing others website by actually removing the sitemap form google.

Google is so fast nowadays it doesn't matter that much, as it won't be in index before index update. I could be wrong as things change all the time, but thats my personal experience and from readup. Also if you add a sitemap page to your site will help if you really worry about it. As with most seo things you have to take everything with a grain of salt at the end.

It's maybe ok if google doesn't come to your new site if it's new, but tests have shown even only 1 link to your site and google will parse it in 1 day if you have a nice structure.

      Some of you might have followed the development of this module here: https://processwire.com/talk/topic/15524-previewdiscussion-rockdatatables/ . It is the successor of "RockDataTables" and requires RockFinder to get the data for the grid easily and efficiently. It uses the open source part of agGrid for grid rendering.
      ProcessWire is awesome for creating all kinds of custom backend applications, but where it is not so awesome in my opinion is when it comes to listing this data. Of course we have the built in page lister and we have ListerPro, but none of that solutions is capable of properly displaying large amounts of data, for example lists of revenues, aggregations, quick and easy sorts by the user, instant filter and those kind of features. RockGrid to the rescue 😉 
      100k+ rows Instant (client side) filter, search, sort (different sort based on data type, eg "lower/greater than" for numbers, "contains" for strings) extendable via plugins (available plugins at the moment: fullscreen, csv export, reload, batch-processing of data, column sum/statistics, row selection) all the agGrid features (cell renderers, cell styling, pagination, column grouping etc) vanilla javascript, backend and frontend support (though not all plugins are working on the frontend yet and I don't plan to support it as long as I don't need it myself)  
      While there is an option to retrieve data via AJAX the actual processing of the grid (displaying, filtering, sorting) is done on the client side, meaning that you can get into troubles when handling really large datasets of several thousands of rows. agGrid should be one of the most performant grid options in the world (see the official example page with a 100k row example) and does a lot to prevent problems (such as virtual row rendering), but you should always have this limitation in mind as this is a major difference to the available lister options that do not have this limitation.
      Currently it only supports AdminThemeUikit and I don't plan to support any other admin theme.

      Use Cases / Examples:
      Colored grid cells, Icons, Links etc. The Grid also has a "batcher" feature built in that helps communicating with the server via AJAX and managing resource intensive tasks in batches:

      Filters, PW panel links and instant reload on panel close:

      You can combine the grid with a chart library like I did with the (outdated) RockDataTables module:

      As we often use Matomo (former known as Piwik) instead of Google Analytics we wanted to embed Matomo not only in the template code but also via the ProcessWire backend.
      That's why I developed a tiny module for the implementation.
      Right now it's not heavily tested, so I would call it an "alpha" status.
      The module provides the possibility to connect to an existing Matomo installation with the classical site tracking and also via the Matomo Tag Manager.
      If you have also PrivacyWire installed, you can tell MatomoWire to only load the script, if the user has accepted cookies via PrivacyWire.
      To offer an Opt-Out solution you can choose between the simple Opt-Out iFrame, delivered by your Matomo installation, or a button to choose cookies via PrivacyWire.
      You'll find the current (alpha) state in this git repo: https://github.com/blaueQuelle/matomowire
      As soon as it's better tested, I'll add it to the module repo.
      I'm looking forward to hear your feedback!

      Hello community!

      I want to share a new module I've been working on that I think could be a big boost for multi-language ProcessWire sites.

      Some background, I was looking for a way for our company website to be efficiently translated as working with human translators was pretty laborious and a lack of updating content created a divergence between languages. I, and several other devs here, have talked about translation integrations and have recognized the power that DeepL has. DeepL is an AI deep learning powered service that delivers translation quality beyond any automated service available. After access to the API was opened up to the US, I built Fluency, a DeepL translation integration for ProcessWire.
      Fluency brings automated translation to every multi-language field in the admin, and also provides a translation tool allowing the user to translate their text to any language without it being inside a template's field. With Fluency you can:
      Translate any plain textarea or text input Translate any CKEditor content (yes, with markup) Translate page names for fully localized URLs on every page Translate your in-template translation function wrapped strings Translate modules DeepL offers translations to the following languages: English (US), English (UK), German, French, Spanish, Portuguese (EU), Portuguese (Brazil, Italian, Dutch, Polish, Russian, Japanese, Chinese (Simplified)
      Installation and usage is completely plug and play. Whether you're building a new multi-language site, need to update a site to multi-language, or simply want to stop manually translating a site and make any language a one-click deal, it could not be easier to do it. Fluency works by having you match the languages configured in ProcessWIre to DeepL's. You can have your site translating to any or all of the languages DeepL translates to in minutes (quite literally).
      Let's break out the screenshots...
      When the default language tab is shown, a message is displayed to let users know that translation is available. Clicking on each tab shows a link that says "Translate from English". Clicking it shows an animated overlay with the word "Translating..." cycling through each language and a light gradient shift. Have a CKEditor field? All good. Fluency will translated it and use DeepL's ability to translate text within HTML tags. CKEditor fields can be translated as easily and accurately as text/textarea fields.

      Repeaters and AJAX created fields also have translation enabled thanks to a JavaScript MutationObserver that searches for multi-language fields and adds translation as they're inserted into the DOM. If there's a multi-language field on the page, it will have translation added.

      Same goes for image description fields. Multi-language SEO friendly images are good to go.

      Creating a new page from one of your templates? Translate your title, and also translate your page name for native language URLs. (Not available for Russian, Chinese, or Japanese languages due to URL limitations). These can be changed in the "Settings" tab for any page as well so whether you're translating new pages or existing pages, you control the URLs everywhere.

      Language configuration pages are no different. Translate the names of your languages and search for both Site Translation Files (including all of your modules)

      Translate all of the static text in your templates as well. Notice that the placeholders are retained. DeepL is pretty good at recognizing and keeping non-translatable strings like that. If it is changed, it's easy to fix manually.

      Fluency adds a "Translate" item to the CMS header. When clicked this opens up a modal with a full translation tool that lets the user translate any language to any language. No need to leave the admin if you need to translate content from a secondary language back to the default ProcessWire language. There is also a button to get the current API usage statistics. DeepL account owners can set billing limitations via character count to control costs. This may help larger sites or sites being retrofitted keep an eye on their usage. This tool is available for all users with the page-edit permission.

      It couldn't be easier to add Fluency to your new or existing website. Simply add your API key and you're shown what languages are currently available for translation from/to as provided by DeepL. This list and all configuration options are taken live from the API so when DeepL releases new languages you can add them to your site without any work. No module updates, just an easy configuration. Just match the language you configured in ProcessWire to the DeepL language you want it to be associated with and you're done. Fluency also allows you to create a list of words/phrases that will not be translated which can prevent items such as brands and company names from being translated when they shouldn't

      No "translate page" - Translating multiple fields can be done by clicking multiple translation links on multiple fields at once but engineering a "one click page translate" is not feasible from a user experience standpoint. The time it takes to translate one field can be a second or two, but cumulatively that may take much longer (CKEditor fields are slower than plain text fields). There may be a workaround in the future but it isn't currently on the roadmap. No "translate site" - Same thing goes for translating an entire website at once. It would be great, but it would be a very intense process and take a very (very) long time. There may be a workaround in the future but it isn't on the roadmap. No current support for Inline CKEditor fields - Handling for CKEditor on-demand hasn't been implemented yet, this is planned for a future release though and can be done. I just forgot about it because I've never really used that feature personally.. Alpha release - This module is in alpha. Releases should be stable and usable, but there may be edge case issues. Test the module thoroughly and please report any bugs via a Gitlab issue on the repository or respond here. Please note that the browser plugin for Grammarly conflicts with Fluency (as it does with many web applications). To address this issue it is recommended that you disable Grammarly when using Fluency, or open the admin to edit pages in a private window where Grammarly may not be loaded. This is an issue that may not have a resolution as creating a workaround may not be possible. If you have insight as to how this may be solved please visit the Gitlab page and file a bugfix ticket.
      ProcessWire  3.0+ UIKit Admin Theme That's Fluency in a nutshell. A core effort in this module is to create it so that there is nothing DeepL related hard-coded in that would require updating it when DeepL offers new languages. I would like this to be a future-friendly module that doesn't require developer work to keep it up-to-date.
      It's Free
      This is my first real module and I want to give it back to the community as thanks. This is the best CMS I've worked with (thank you Ryan & contributors) and a great community (thank you dear reader). The only cost to use this is a subscription fee for the DeepL Pro API.

        when working with PW version 2.6+, please use Pim2, not Pim!
        read more here  on how to change from the older to the newer version in existing sites
      PageImage Manipulator, API for version 1 & 2

      The Page Image Manipulator is a module that let you in a first place do ImageManipulations with your PageImages. - And in a second place there is the possibility to let it work on any imagefile that exists in your servers filesystem, regardless if it is a 'known PW-image'.

      The Page Image Manipulator is a Toolbox for Users and Moduledevelopers. It is written to be as close to the Core ImageSizer as possible. Besides the GD-filterfunctions it contains resize, crop, canvas, rotate, flip, sharpen, unsharpMask and 3 watermark methods.

      How does it work?

      You can enter the ImageManipulator by calling the method pim2Load(). After that you can chain together how many actions in what ever order you like. If your manipulation is finished, you call pimSave() to write the memory Image into a diskfile. pimSave() returns the PageImage-Object of the new written file so we are able to further use any known PW-image property or method. This way it integrates best into the ProcessWire flow.

      The three examples above put out the same visual result: a grayscale image with a width of 240px. Only the filenames will slightly differ.

      You have to define a name-prefix that you pass with the pimLoad() method. If the file with that prefix already exists, all operations are skipped and only the desired PageImage-Object gets returned by pimSave(). If you want to force recreation of the file, you can pass as second param a boolean true: pim2Load('myPrefix', true).

      You may also want to get rid of all variations at once? Than you can call $pageimage->pim2Load('myPrefix')->removePimVariations()!

      A complete list of all methods and actions are at the end of this post.
      You may also visit the post with tips & examples for users and module developers.

      quality = 1 - 100 (integer) upscaling = true | false (boolean) cropping = true | false (boolean) autoRotation =true | false (boolean) sharpening = 'none' | 'soft' | 'medium' | 'strong' (string) bgcolor = (array) css rgb or css rgba, first three values are integer 0-255 and optional 4 value is float 0-1, - default is array(255,255,255,0) thumbnailColorizeCustom = (array) rgb with values for colorize, integer -255 - 255 (this can be used to set a custom color when working together with Thumbnails-Module)
        outputFormat = 'gif' | 'jpg' | 'png' (Attention: outputFormat cannot be specified as global option in $config->imageManipulatorOptions!) set {singleOption} ($value)
      For every valid option there is also a single method that you can call, like setQuality(90), setUpscaling(false), etc.

      * pimSave

      return: PageImage-Object If a new image is hold in memory, it saves the current content into a diskfile, according to the settings of filename, imagetype, targetFilename and outputFormat. Returns a PageImage-Object!

      * release

      return: void (nothing) if you, for what ever reason, first load image into memory but than do not save it, you should call release() to do the dishes! 😉 If you use pimSave() to leave the ImageManipulator, release() is called automatically.

      * getOptions

      return: associative array with all final option values example:
      ["autoRotation"] bool(true) ["upscaling"] bool(false) ["cropping"] bool(true) ["quality"] int(90) ["sharpening"] string(6) "medium" ["targetFilename"] string(96) "/htdocs/site/assets/files/1124/pim_prefix_filename.jpg" ["outputFormat"] string(3) "jpg" get {singleOption} ()
      For every valid option there is also a single method that you can call, like getQuality(), getUpscaling(), etc. See method setOptions for a list of valid options!

      * getImageInfo

      return: associative array with useful informations of source imagefile example:
      ["type"] string(3) "jpg" ["imageType"] int(2) ["mimetype"] string(10) "image/jpeg" ["width"] int(500) ["height"] int(331) ["landscape"] bool(true) ["ratio"] float(1.5105740181269) ["bits"] int(8) ["channels"] int(3) ["colspace"] string(9) "DeviceRGB" -------------------------------------------------------------------

      * getPimVariations

      return: array of Pageimages Collect all pimVariations of this Pageimage as a Pageimages array of Pageimage objects. All variations created by the core ImageSizer are not included in the collection.

      * removePimVariations

      return: pim - (class handle) Removes all image variations that was created using the PIM, all variations that are created by the core ImageSizer are left untouched!
      * width

      width($dst_width, $sharpen_mode=null)
      param: $dst_width - (integer) param: $auto_sharpen - (boolean) default is true was deleted with version 0.0.8, - sorry for breaking compatibility param: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you prioritize the width, like with pageimage. Additionally, after resizing, an automatic sharpening can be done with one of the three modes.

      * height

      height($dst_height, $sharpen_mode=null)
      param: $dst_height - (integer) param: $auto_sharpen - (boolean) default is true was deleted with version 0.0.8, - sorry for breaking compatibility param: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you prioritize the height, like with pageimage. Additionally, after resizing, an automatic sharpening can be done with one of the three modes.

      * resize

      resize($dst_width=0, $dst_height=0, $sharpen_mode=null)
      param: $dst_width - (integer) default is 0 param: $dst_height - (integer) default is 0 param: $auto_sharpen - (boolean) default is true was deleted with version 0.0.8, - sorry for breaking compatibility param: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you have to set width and / or height, like with pageimage size(). Additionally, after resizing, an automatic sharpening can be done with one of the three modes.

      * stepResize

      stepResize($dst_width=0, $dst_height=0)
      param: $dst_width - (integer) default is 0 param: $dst_height - (integer) default is 0 return: pim - (class handle) this performs a resizing but with multiple little steps, each step followed by a soft sharpening. That way you can get better result of sharpened images.

      * sharpen

      param: $mode - (string) possible values 'none' | 'soft'| 'medium'| 'strong' return: pim - (class handle) Applys sharpening to the current memory image. You can call it with one of the three predefined pattern, or you can pass an array with your own pattern.

      * unsharpMask

      unsharpMask($amount, $radius, $threshold)
      param: $amount - (integer) 0 - 500, default is 100 param: $radius - (float) 0.1 - 50, default is 0.5 param: $threshold - (integer) 0 - 255, default is 3 return: pim - (class handle) Applys sharpening to the current memory image like the equal named filter in photoshop.
      Credit for the used unsharp mask algorithm goes to Torstein Hønsi who has created the function back in 2003.

      * smooth

      param: $level - (integer) 1 - 255, default is 127 return: pim - (class handle) Smooth is the opposite of sharpen. You can define how strong it should be applied, 1 is low and 255 is strong.

      * blur

      return: pim - (class handle) Blur is like smooth, but cannot called with a value. It seems to be similar like a result of smooth with a value greater than 200.

      * crop

      crop($pos_x, $pos_y, $width, $height)
      param: $pos_x - (integer) start position left param: $pos_y - (integer) start position top param: $width - (integer) horizontal length of desired image part param: $height - (integer) vertical length of desired image part return: pim - (class handle) This method cut out a part of the memory image.

      * canvas

      canvas($width, $height, $bgcolor, $position, $padding)
      param: $width = mixed, associative array with options or integer, - mandatory! param: $height = integer, - mandatory if $width is integer! param: $bgcolor = array with rgb or rgba, - default is array(255, 255, 255, 0) param: $position = one out of north, northwest, center, etc, - default is center param: $padding = integer as percent of canvas length, - default is 0 return: pim - (class handle) This method creates a canvas according to the given width and height and position the memory image onto it.
      You can pass an associative options array as the first and only param. With it you have to set width and height and optionally any other valid param. Or you have to set at least width and height as integers.
      Hint: If you want use transparency with rgba and your sourceImage isn't of type PNG, you have to define 'png' as outputFormat with your initially options array or, for example, like this: $image->pimLoad('prefix')->setOutputFormat('png')->canvas(300, 300, array(210,233,238,0.5), 'c', 5)->pimSave()

      * flip

      param: $vertical - (boolean) default is false return: pim - (class handle) This flips the image horizontal by default. (mirroring)
      If the boolean param is set to true, it flips the image vertical instead.

      * rotate

      rotate($degree, $backgroundColor=127)
      param: $degree - (integer) valid is -360 0 360 param: $backgroundColor - (integer) valid is 0 - 255, default is 127 return: pim - (class handle) This rotates the image. Positive values for degree rotates clockwise, negative values counter clockwise. If you use other values than 90, 180, 270, the additional space gets filled with the defined background color.

      * brightness

      param: $level - (integer) -255 0 255 return: pim - (class handle) You can adjust brightness by defining a value between -255 and +255. Zero lets it unchanged, negative values results in darker images and positive values in lighter images.

      * contrast

      param: $level - (integer) -255 0 255 return: pim - (class handle) You can adjust contrast by defining a value between -255 and +255. Zero lets it unchanged, negative values results in lesser contrast and positive values in higher contrast.

      * grayscale

      return: pim - (class handle) Turns an image into grayscale. Remove all colors.

      * sepia

      return: pim - (class handle) Turns the memory image into a colorized grayscale image with a predefined rgb-color that is known as "sepia".

      * colorize

      param: $anyColor - (array) like css rgb or css rgba - but with values for rgb -255 - +255,  - value for alpha is float 0 - 1, 0 = transparent  1 = opaque return: pim - (class handle) Here you can adjust each of the RGB colors and optionally the alpha channel. Zero lets the channel unchanged whereas negative values results in lesser / darker parts of that channel and higher values in stronger saturisation of that channel.

      * negate

      return: pim - (class handle) Turns an image into a "negative".

      * pixelate

      param: $blockSize - (integer) 1 - ??, default is 3 return: pim - (class handle) This apply the well known PixelLook to the memory image. It is stronger with higher values for blockSize.

      * emboss

      return: pim - (class handle) This apply the emboss effect to the memory image.

      * edgedetect

      return: pim - (class handle) This apply the edge-detect effect to the memory image.

      * getMemoryImage

      return: memoryimage - (GD-Resource) If you want apply something that isn't available with that class, you simply can check out the current memory image and apply your image - voodoo - stuff

      * setMemoryImage

      param: $memoryImage - (GD-Resource) return: pim - (class handle) If you are ready with your own image stuff, you can check in the memory image for further use with the class.

      * watermarkLogo

      watermarkLogo($pngAlphaImage, $position='center', $padding=2)
      param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW,
      - or: north, east, south, west, center, northeast, southeast, southwest, northwest
      default is 'center' param: $padding - (integer) 0 - 25, default is 5, padding to the borders in percent of the images length! return: pim - (class handle) You can pass a transparent image with its filename or as a PageImage to the method. If the watermark is bigger than the destination-image, it gets shrinked to fit into the targetimage. If it is a small watermark image you can define the position of it:
      NW - N - NE | | | W - C - E | | | SW - S - SE  
      The easiest and best way I have discovered to apply a big transparency watermark to an image is as follows:
      create a square transparent png image of e.g. 2000 x 2000 px, place your mark into the center with enough (percent) of space to the borders. You can see an example here! The $pngAlphaImage get centered and shrinked to fit into the memory image. No hassle with what width and / or height should I use?, how many space for the borders?, etc.

      * watermarkLogoTiled

      param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency return: pim - (class handle) Here you have to pass a tile png with transparency (e.g. something between 150-300 px?) to your bigger images. It got repeated all over the memory image starting at the top left corner.

      * watermarkText

      watermarkText($text, $size=10, $position='center', $padding=2, $opacity=50, $trueTypeFont=null)
      param: $text - (string) the text that you want to display on the image param: $size - (integer) 1 - 100, unit = points, good value seems to be around 10 to 15 param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW,
      - or: north, east, south, west, center, northeast, southeast, southwest, northwest
      default is 'center' param: $padding - (integer) 0 - 25, default is 2, padding to the borders in percent of the images length! param: $opacity- (integer) 1 - 100, default is 50 param: $trueTypeFont - (string) systemfilepath to a TrueTypeFont, default is freesansbold.ttf (is GPL & comes with the module) return: pim - (class handle) Here you can display (dynamic) text with transparency over the memory image. You have to define your text, and optionally size, position, padding, opacity for it. And if you don't like the default font, freesansbold, you have to point to a TrueTypeFont-File of your choice.
