Page Image Manipulator | API for 1 & 2

Recommended Posts

Hi Horst,

pim2 v0.2.9 running on PW 2.8.62 overwrites the original image instead of making a variation.

I'm using the canvas method

<img src="<? echo $image->pim2Load('pim')->setQuality(90)->setOutputFormat('png')->canvas(240,160)->pimSave()->httpUrl; ?>">

chears,
JFN.

 

Is this thread abandoned??

Good day, @horst!

Was messing with an old site of mine. I did not even remember I used pim2 on this one. And getting to use this powerful tool once again was a pleasure. Thank you for your work!

I had to make a overblurred version of an image for a background. So I used smooth(255) about a 10 times in a row. That did the trick, but the code looks kind of ugly. Am I missing some shortcut way to do it in a more beautiful manner?

Hi @Ivan Gretsky, thanks for the nice words.

To make an image overblurred, there is only the "blur" and the "smooth" functions. But maybe you can experiment with using "pixelate" before "smooth"?

pixelate(2) or pixelate(3) and then smooth(255), (regarding your desription, maybe 2-3 times smooth(255))

Or isn't that what you are asking for?

@Ivan Gretsky, if you have Imagick installed you could use this function I wrote a while back for easy ImageMagick effects:

It does quite a nice blur. But now that supporting IE is less of an issue you could also try a CSS filter.

Hi Jonathan, sorry, I completly missed that one. 😳

Will looking into it next week. 🤞

And thanks for showing the issue by video, what makes it very clear to follow!

@Jonathan Lahijani Hmm, there is no fast fix possible ATM. BUT you may use this code, passing the options array as second param to pim2Load, what works as expected:

$image1->pim2Load('i1')->setOptions(['outputFormat'=>'jpg'])->pimSave(); // FAILES (with outputFormat, all other settings work as expected)
$image2->pim2Load('i2', ['outputFormat'=>'jpg'])->pimSave();  // works!!

Summary: all option settings work in both ways, BUT changing the outputFormat only works correctly when passed as options argument into pim2Load().

(I think it needs a massive rewrite to fix that properly, for that I have no time atm 😞)

There are serious issues with this module running PW 3.0.123+. Didn't have time to debug properly, but on different sites the pim2load didn't work anymore.

Two different examples that didn't work anymore:
$img->pim2Load('img_name')->width(640)->grayscale()->setQuality(80)->pimSave()->url;
$img->pim2Load('img_name')->setQuality(90)->setOutputFormat('png')->canvas(240,160)->pimSave()->httpUrl;

I ended up disabling the module and using core image manipulations (except for the grayscale... it looks much better in color anyway 😎)

@JFn I cannot confirm this. I tested with different newer PW versions up to 3.0.131. Everything is working as expected and like with older PW versions.

Only thing from your examples that did not work, is to use the ->setOutputFormat(). How to handle this, please read my post directly above yours.

Just a heads up, I'm getting this warning on PHP 7.3.6 :

Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /home/zzzzzz/dev/site/assets/cache/FileCompiler/site/modules/PageImageManipulator/ImageManipulator02.class.php on line 525

@Macrura thanks for the hint.

Have you tried to change that continue into break at line 525? Does it solve the Warning?

yes, it solves the warning for sure.

On a separate topic – is there anyway to set the color of watermark text?

Sorry, no. The current text watermark method analyzes the images and decides between white, gray and black in a automated way. The reason behind that is, you can apply text to any images without knowing which colors it includes.

I am using this module (v0.2.9) to generate low quality previews for use with lazysizes js using following code

$imgLow = $img->pim2Load('lowq', true)->setOptions(['quality' => 20])->pixelate(3)->smooth(255)->pimSave();

This is working fine but I quite frequently get a warning:

PHP Warning: rename(/home/m1698/Sites/processwire/site/assets/files/14172/p1010866_geschnitten-1.780x0-pim2-lowq.jpg.tmp,/home/m1698/Sites/processwire/site/assets/files/14172/p1010866_geschnitten-1.780x0-pim2-lowq.jpg): No such file or directory in /home/m1698/Sites/processwire/site/assets/cache/FileCompiler/site/modules/PageImageManipulator/ImageManipulator02.class.php:715

It seems that the warning is thrown by rename() because it is being executed on a non existing file ($dest). Somehow $dest must have been deleted.

But strange enough, the renamed file exists. So the rename operation seems to have been run successfully.

Any idea what might be causing this?

Thank you for this great module.

In the log I find multiple of these exceptions:

Error when trying to resize watermarkLogo to fit to the MemoryImage. (in /site/assets/cache/FileCompiler/site/modules/PageImageManipulator/ImageManipulator02.class.php line 1986)

My guess is that some of the images that I am trying to resize are too large (but I am not sure).

Any suggestion how to fix this, so I can avoid fatal exceptions?

Some infos may help. How are the dimensions of the images (orig images and the watermark image) How much is the dedicated memory for PHP on your server / account?

ProcessWire 3.0.98
Pageimage Manipulator 2    0.2.9

Some files(?) put pim2 in endless loop . Loop in ImageManipulator02.class.php :

        public function __construct($entryItem=null, $options=array(), $bypassOperations=false) {

            // version check module == class
            $m = wire('modules')->get('PageImageManipulator02')->getModuleInfo();
            $m = preg_replace('/(\d)(?=\d)/', '$1.', str_pad("{$m['version']}", 3, "0", STR_PAD_LEFT));
            $c = preg_replace('/(\d)(?=\d)/', '$1.', str_pad("{$this->version}", 3, "0", STR_PAD_LEFT));
            if(!version_compare($m, $c, '=')) {
                throw new WireException("The versions of Module PageImageManipulator02 ($m) and it dependency classfile ImageManipulator02 ($c) are inconsist
ent!)");
                return;
            }

            $this->bypassOperations = true===$bypassOperations ? true : false;
            // validate PageImage, FileImage, MemoryImage

            if($entryItem instanceof Pageimage) {

                $this->pageimage = $entryItem;
                $this->entryItem = 'page';
                $this->filename = $entryItem->filename;
                $this->isOriginal = $entryItem->original===NULL ? true : false;

                if(!$this->isOriginal) {
                    // traversing up 'til reaching root reference
                    $this->originalImage = $entryItem->original;
                    while(null !== $this->originalImage->original) {
					// !!!!!!!!!!!! ENDLESS LOOP HERE !!!!!!!!!!!!!!!!!!!!!!!
                        $reference = $this->originalImage->original;
                        $this->originalImage = $reference;
                    }
                }

Thanks for the replies.

I use PW 3.0.148 and PIM2 0.2.9.

Here is my code:

$imgWidth = 255;
$imgHeight = 312;
$imgPadding = 5;

$image->pim2Load($product->title)->setOutputFormat('png')->canvas($imgWidth, $imgHeight, array(255, 255, 255, 0) ,'center', $imgPadding)->pimSave();

Actually @ak1001 suggestion of a endless loop, sounds more plausible than it is caused by a too large image.

I use a function to selected random images to display, so currently I do not know which source-images are causing the exception.

Investigating further, in my case problem i think with some file names.  For example one page with three images break down on image named 30x30.jpg. I think processwire thinks that it is a variation image forewer.

mysql> select pages_id, data, sort from field_tovarimages where pages_id = 9771;
+----------+--------------+------+
| pages_id | data         | sort |
+----------+--------------+------+
|     9771 | 30_belyi.jpg |    0 |
|     9771 | 19480.jpg    |    1 |
|     9771 | 30x30.jpg    |    2 |
+----------+--------------+------+
3 rows in set (0.00 sec)

So in  pim 

$this->originalImage == $this->originalImage->original
                       

and it makes loop ?

So,  public function ___isVariation in class Pageimage have a regexp 

$re1 = '/^'  ..
   '(\d+)x(\d+)' .>    // 50x50 
   '([pd]\d+x\d+|[a-z]{1,2})?' . <>// nw or p30x40 or d30x40
   '(?:-([-_a-z0-9]+))?' .   // -suffix1 or -suffix1-suffix2, etc.
   '\.' . $this->ext() . <>  // .jpg
   '$/';

that will match names like 30x30.jpg and always says this is a variation image. And this will cause the pim go in endless loop. Don't know is there some consequnces for processwire, seems only pim react abnormally.

I will rename all images for now, and will ask users to not use such type names, but some prevention methods must be used i think

Hi @ak1001, many thanks for your investigations.

Please can you provide me with some informations, so that I can test it locally here, and try to update the ___isVariation stuff to fit with recent PW versions?

(When pim was build, we don't have had imge-rendering-engines and the image structures as it is today. We only have had the imagesizer.php and the pageimage.php, where I copy pasted that method from.) 

Which version of PW are you using:

Do you use Pim1 or Pim2:

Which module version of Pim:

What is the exact full URL of the image(s) in question:

Hi @horst
ProcessWire 3.0.98

exact urls something like site/assets/files/9771/30x30.jpg
pim image : site/assets/files/9771/30x30.-pim2-wm3.jpg

Also i was lazy to rename images so i just count loops in PageImageManipulator02.class.php

Hi! I just found a problem adding a watermar when 2 different images have the same name but the extensions are jpg and jpeg the result is only one image.

I fixed it commenting lines 554 to 556 on ImageManipulator02.class.php file.

Eg: "photo1.jpg" and "photo1.jpeg"

foreach ($images as $img){
     $img->pim2Load("wtmd", true)->height(480)->watermarkLogo($watermark, $position = 'center', $padding = 2)->pimSave()->httpUrl;
} // The result is photo1.jpg

Hello @horst me again with problems. Tried to enable webp support and get this error:

imagen.thumb.png.beeb29d31bef03ab15da546108263571.png

"Error when trying to save the MemoryImage: we have no Targetfilename!
In /site/assets/cache/FileCompiler/site/modules/PageImageManipulator/ImageManipulator02.class.php line 674"

I'm using your implementation with the Strategy 1 from this post:
https://processwire.com/blog/posts/webp-images-and-more/#strategy-1-automatically-delivering-webp-for-jpg-png-images

Everything works until I need to create the image with the watermark.

The code for the watermark is:

$image_url = $prop->images->eq(0)->pim2Load("wtm",true)->height(480)->watermarkLogo($watermark, $position='center', $padding=2) ->pimSave()->url;

Thank you!

      Hey folks,
      for a module (a pagebuilder based on PageTable) I need to save some settings as JSON. The values are saved for each page table item (a pw page). It's working well, but I am looking for ways to improve the structure I have. As I'm not that experienced with JSON, maybe someone more experienced can take a look and tell me if my approach is good practice. 

      My goal is to make all the items accessible by page id, without looping over them (using objects instead of arrays):
      // access from template with pw page var $jsonObject->items->{$page}->cssClass; Her is an example of my JSON structure:
      { "items": { "3252": { "id": "3252", "cssClass": "pgrid-main", "breakpoints": { "base": { "css": { "grid-column-end": "auto", "grid-row-end": "auto", "grid-column-start": "auto", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "60px", "padding-right": "60px", "padding-top": "60px", "padding-bottom": "60px", "background-color": "rgb(255, 255, 255)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } }, "3686": { "id": "3686", "cssClass": "test_global", "breakpoints": { "base": { "css": { "grid-column-end": "-1", "grid-row-end": "span 1", "grid-column-start": "1", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "0px", "padding-right": "0px", "padding-top": "0px", "padding-bottom": "0px", "background-color": "rgba(0, 0, 0, 0)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } }, "3687": { "id": "3687", "cssClass": "block_editor-3687", "breakpoints": { "base": { "css": { "grid-column-end": "span 2", "grid-row-end": "span 1", "grid-column-start": "auto", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "0px", "padding-right": "0px", "padding-top": "0px", "padding-bottom": "0px", "background-color": "rgba(0, 0, 0, 0)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } }, "3696": { "id": "3696", "cssClass": "block_editor-3696", "breakpoints": { "base": { "css": { "grid-column-end": "span 2", "grid-row-end": "span 1", "grid-column-start": "auto", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "0px", "padding-right": "0px", "padding-top": "0px", "padding-bottom": "0px", "background-color": "rgba(0, 0, 0, 0)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } } }, "breakpointActive": "base", "breakpointActiveSize": "@media (min-width: 576px)" }

      Fieldtype Page Table Grid
      This is a sneak preview of a side project I've been working on for quite some time now. A lot of work and thought has gone into this, so I will most likely release this as a commercial module at some point in the near future. 

      As a designer (and developer) I get the appeal of a WYSIWYG editor. After playing around with some WYSIWYG page builder tools, I always felt something was wrong about them. So I decided to build my own PW version based on PageTable.

      Here is a small demo (using AdminThemeCanvas, but its working with other admin themes as well) :
      There is also a complete website that I built for a friend of mine using this module and some custom blocks.
      Concept
      This fieldtype shares a lot of features with PageTableExtended: it's also an extension of PageTable and renders the block templates in the backend and frontend (native PW templates and fields). You can also add your own css via module settings.
      The difference is, this fieldtype also gives you the ability to rearrange and resize elements in a visual way as well as enable inline editing for text, ckeditor and file fields. Similar (and promising) attempts have been made, but I wanted something based on native CSS grid instead of a CSS framework...so I built my own version. Most CSS frameworks are based on flexbox, which is great for layouting elements horizontally. With CSS grid, you can place elements horizontally and vertically, allowing for layouts that were not previously possible with CSS. Similar to webflow, this fieldtype uses javascript (in the backend) to let you manipulate CSS grid in a visual way to design fully responsive websites (or parts of them). It should still be possible to include a CSS framework if you like (just add the classes to your block markup and include the CSS via module settings).
      The CSS grid layout manipulations are saved in a single field as a JSON array and used to generate a dynamic stylesheet that you simply include in your main template (no inline styles). The styles are saved within the breakpoint you select and cascade down to smaller breakpoints. That means you can specify just the basic breakpoint and adjust other breakpoints if needed. The exception is the mobile breakpoint which will display everything in one column as a default (you can change the layout here too).
      The fieldtype also comes with an optional style panel to manipulate some additional CSS properties directly on the page. You can customize the panel or disable it completely from the module settings (and just use a CSS file that you include via module settings). The style panel is based on inputfields (nothing is saved to the database). This means that you just have to install the module and all fields are available to all blocks automatically (this can be customized). It also has the benefit that your installation is not flooded with fields; this module only installs one field.
      Don't want to give your customer all that power? Design features can be disabled for certain roles. The grid editor role can just edit the content and use the inline editing feature to edit content quickly. You can then also grant access individually to the style panel, resize or drag functionality.
      Features
      Blocks are just pages Blocks are defined by native PW templates and fields Manipulate CSS grid in a visual way to design fully responsive websites (or parts of them) Design features can be disabled for certain roles Inline editing of text, ckeditor and file fields The layout is 100% CSS grid (very small css file size) Simply drag and resize to manipulate grid items directly inside the backend Manipulate grid columns and rows directly on the page (use any number of columns you want) All style manipulations are saved as JSON and used to generate a dynamic stylesheet that you just include in your main template (no inline styles) Nested groups/grids (child pages of nested blocks are created under group parent) Global blocks work with page reference field (changes on one page, changes all blocks on all pages) Manual and auto placement of grid items Define custom icons for your blocks via native template settings (template -> advanced -> icon) Option to load lazysizes in the backend to enable lazy loading of assets with class lazyload Works with all default and ui-kit based admin themes If you have any questions or feedback, let me know.

      I built this module because I needed a versatile solution to replace tags and simple if-blocks in some E-Mails and PDF documents.
      If you only need to replace static tags (no if-conditions), then you can use default PW api and need no module:
      $str = "My favourite color is {color}."; $texttools = $sanitizer->getTextTools(); echo $texttools->populatePlaceholders($str, ['color' => 'red']); // output: My favourite color is red. Usage:
      See the two example Files in the folder /replacements

       
      Methods:
      replacementsTable()
      Renders an overview of all available replacements (see the example in the Module's config file:
       
      Create new Replacements:
      Simply copy the sample file and adopt to your needs.

      DEPRECATED
      I'm using this module in several projects, but it will likely not see any updates in the future. I'm not happy with it and I'm looking for ways to develop better solutions. RockTabulator was my first try, but I'm also not 100% happy with that. The tabulator library is great, but my module implementation is not. I hope to get a good solution soon, but it will be a lot of work...
      ---
      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.
       
      WHY?
      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 😉 
       
      Features/Highlights:
      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)  
      Limitations:
      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.

      Note that every installation and uninstallation sends an anonymous google analytics event to my google analytics account. If you don't want that feel free to remove the appropriate lines of code before installation/uninstallation.
       
      Contribute:
      You can contribute to the development of this and other modules or just say thank you by
      testing, reporting issues and making PRs at gitlab liking this post buying me a drink: paypal.me/baumrock/5 liking my facebook page: facebook.com/baumrock hiring me for pw work: baumrock.com  
      Support: Please note that this module might not be as easy and plug&play as many other modules. It needs a good understanding of agGrid (and JavaScript in general) and it likely needs some looks into the code to get all the options. Please understand that I can not provide free support for every request here in the forum. I try to answer all questions that might also help others or that might improve the module but for individual requests I offer paid support (please contact me via PM).
       
      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:

      Hi there. I wrote a custom module for one of my projects. In fact I maybe want to use my module in other projects too. In order to be variable and customizable  I need to implement some custom hooks into my module. So I can afterwards hook into the my functions in order to modify them to match the needs of the new project.
      I tried simply defining functions with the '__' prefix. But that did not work. I'm imagining something like the following:
      <?php class MyClass { public function ___someFunction() { // Do something } } // ready.php $this->addHookBefore('MyClass::someFunction', function($event) { // some customization }); Is there a way to accomplish that?
