Hi Wanze,

Sorry for the late reply but I have since uninstalled the module and have used a plain 'file' field to solve my problem.

Thank you,

Matt

Whoops, Ultra-PEBDAC.

(I was asking about the font issue that adrian kindly resolved below, but my real issue was that I was uploading files to the wrong server - we are in the midst of switching hosts!)

I'm getting the error "mPDF Error - cannot find TTF TrueType font file

I just installed this on a site a couple of days ago and got the same error. I took the lazy approach of just adding all the fonts from the mpdf github repo:

Thanks adrian! I've saved this folder for future installations to make it faster. I was certain it was a cache issue but my real issue was webhost related. I fixed it and it works like the charm I knew it would!

(I'm sure I'll be back as I customize these files, but hopefully I'll think through all my possible user-errors first!)

Thanks for the great plugin!

I'm trying to put a piechart in a PDF page. I understand using Javascript is not supported in PDF but with Google Charts it's possible to create an image for print/PDF. So i thought maybe in my template i can first run the Javascript to render an image and use that image in de PDF. This unfortunately doen't work. Is there a way to run some javascript to render an element before the PDF is created?

do you have some user input or are you creating the pdf completely on the server side (like cronjob)? if you have some user input you could create an image of the chart first (eg on button click) and then post this image to your php script and integrate it in your pdf

You would need to store the piechart as image somewhere and use a regular HTML <img> tag to display it in the template of your PDF. Is it possible for Google Charts to store images on the file system? Though a server side app generating the piechart would probably be simpler in this case.

I am able to create the image on a button click but how would I post it to the PDF template. I tried using $.post but when i try to var_dump the $POST in the PDF it returns an empty array.

As mentioned in my post, as far as I know, you need to render your image in a regular <img> tag inside the PDF template. This means that you'd need to save the image before on the disk or use a base64 encoded string, though I don't know if the latter works in mpdf.

Hi @Wanze

I am using the WirePDF module which works great! The only Problem I have is setting the path to a css fille inside the module settings. Somehow the css file didn't get load no matter which path I type in inside the "CSS File" textfield. 

At the moment my code to generate the pdfs looks like this (working):

$pdf = $modules->get('WirePDF');

if($urlpage->template->name == "jobs"){
	$template = wireRenderFile("partials/pdf_layouts/pdf_jobs_template.php", array(
								"urlpage" => $urlpage
							));
}else{
	$template = wireRenderFile("partials/pdf_layouts/pdf_doctors_template.php", array(
								"urlpage" => $urlpage
							));
}

$pdf->markupMain = $template;
$pdf->setTitle($urlpage->title);
$pdf->download($urlpage->title.".pdf", "D");

ok i could make it to work when I remove this from the header of my css file:

@charset "UTF-8";
/* CSS Document */

And also changed the code to this:

$pdf = $modules->get('WirePDF');
$pdf->setTitle($urlpage->title);
$stylesheet = file_get_contents($config->paths->templates. "styles/pdf_styles.css"); // external css
$pdf->WriteHTML($stylesheet,1);
$pdf->WriteHTML($template,2);
$pdf->download($urlpage->title.".pdf", "D");

I got it to work! The problem was that I was using $.post in jQuery to sent the data to de PDF template. Since $.post doesn't actually goes to the page i added an extra event to load the page. But by doing this i emptied the $POST session... stupid. 

What i'm doing now is first creating a form and setting the img as value and then submitting the form.

        $("body").append($("<form></form>").attr({ "action": PDFurl, "method": "post", "id" : "postForm" })
            .append($('<input>').attr({ "type": "hidden", "name": "img", "value": imgChart.prop("outerHTML") }))
        ).find("#postForm").submit();

A little help if someone has the same problem: images on develpment site were included, but not on live site.

There is no error or any hint, but only a red "x" as placeholder for the image. Try to convert to base64 string included the image to the PDF. For me it even reduced the filesize :D

$imagedata = file_get_contents( "../assets/img/logo-pdf-invoice.png"); // alternatively specify an URL, if PHP settings allow
$base64Img = "data:image/png;base64," . base64_encode($imagedata);

Hi @Wanze,

I am trying something like this but am getting into one error. What I am doing is:

$markupMain = wireRenderFile( 'partials/pdf_invoice', [ 'invoice' => $invoice ] );
$pdf->markupMain = $markupMain;

The error I get is this:

PHP Warning: is_file(): File name is longer than the maximum allowed path length on this platform (260): ...

I looked into the WirePDF.module file and found out, that a check on the markup is tested with if/else on this steps:

  1. $markup instanceof TemplateFile?
  2. is_file($markup)?
  3. is_string($markup)?

Of course my markup is a long HTML string, but check on the markup at point 2 comes up with the warning. PDF is generated, so no problem at this end. Maybe I can ignore this?

Oh, and is it possible to update to a newer version of mPDF, so there could be a better PHP 7 compatibility? I tried to just copy the newer version into the folder, but it was not working, so I wonder what to change on the files.

@godmok

Thanks for the hint on this, I will update this check with a threshold on the string length.

Regarding a newer version of mPDF: Actually the dev brach of the module already contains mPDF 6.1.0, thanks to the work of @gingebaker

However, I didn't find time to test it out yet. I really want to support a more recent mPDF version in the master.

Cheers

Is there an easy way to remove the space occupied by the header? It's probably me or my setup but I can't seem to remove the space.

Hello @Wanze and everyone else,

i'm trying to get pages2pdf with @apeisas Padloper. They way I want to use it is:

 

$t = $this->modules->get("PadRender")->getPadTemplate("invoice.php"); # this simply returns a TemplateFile
$t->set("order", $order);
$pdf = $this->modules->get("WirePDF");
$pdf->pageOrientation = 'P';
$pdf->pageFormat = 'A4';
$pdf->markupMain = $t->render();
$pdf->save($this->config->paths->assets.'/pdf/'.$order->rechnungsnummer.'.pdf');

I'm having problems with the images in the template. Only a red "x" is displayed. I tried full httpUrl and even including the base64 data. No success.

Can anyone help out?

Thanks,

thomas

@thomas

Can you show the code how you output the images in the PDF template? It should work fine to use $image->url.

Do you use pagefileSecure by any chance?

      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

       
      Limitations:
      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.
      Requirements:
      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.


      How to Install

      Page Image Manipulator - Methods

      * pimLoad  or  pim2Load, depends on the version you use!

      pimLoad($prefix, $param2=optional, $param3=optional)
      param 1: $prefix - (string) = mandatory! param 2: mixed, $forceRecreation or $options param 3: mixed, $forceRecreation or $options return: pim - (class handle) $options - (array) default is empty, see the next method for a list of valid options! $forceRecreation - (bool) default is false It check if the desired image variation exists, if not or if forceRecreation is set to true, it prepares all settings to get ready for image manipulation
      -------------------------------------------------------------------

      * setOptions

      setOptions(array $options)
      param: $options - (array) default is empty return: pim - (class handle) Takes an array with any number valid options / properties and set them by replacing the class-defaults and / or the global config defaults optionally set in the site/config.php under imageSizerOptions or imageManipulatorOptions.

      valid options are:
      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

      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

      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

      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

      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

      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

      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

      sharpen($mode='soft')
      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

      smooth($level=127)
      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

      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

      flip($vertical=false)
      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

      brightness($level)
      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

      contrast($level)
      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

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

      * sepia

      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

      colorize($anyColor)
      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

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

      * pixelate

      pixelate($blockSize=3)
      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

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

      * edgedetect

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

      * getMemoryImage

      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

      setMemoryImage($memoryImage)
      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

      watermarkLogoTiled($pngAlphaImage)
      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.

      PageImage Manipulator - Example Output


    • By d'Hinnisdaël
      Format Datetime fields as Carbon instances.
      You can find the latest release and the complete readme on Github.
      Installation
      composer require daun/datetime-carbon-format Usage
      All Datetime fields will now be formatted as Carbon instances instead of strings. Some examples:
      // $page->date is a Datetime field // Output format: j/n/Y echo $page->date; // 20/10/2020 echo $page->date->add('7 days'); // 27/10/2020 echo $page->date->format('l, F j'); // Monday, October 20 echo $page->date->year; // 2020 echo $page->date->diffForHumans(); // 28 minutes ago Frontend only
      The ProcessWire admin seems to expect datetime fields to be strings. This module will only return Carbon instances on frontend page views.
      Date output format
      When casting a Carbon instance to a string (usually when outputting the field in a template), the field's date output format will be respected.

      PS. I remember reading about a Carbon module in a recent newsletter, but couldn't find it anywhere. Was that you, @bernhard?
