Page Image Manipulator | API for 1 & 2

Recommended Posts

Horst: Thanks for the very detailed explanation, It is just happening on the last image or two. It must be a PHP memory getting low (shared hosting account). I will use the PNG watermark method instead.  (thanks for the code example).

Update: my shared hosting account on this site is giving me 64mb of RAM memory limit. I think that might be the issue right there. I tried the PNG method of watermarking, but my site still hangs my server or larger batches 20 images@1,000px.

Have you tried to increase it in the .htaccess file?

Still looking for a workaround to my problem. I'm going to try running it on a slightly newer server configuration to see if it helps.

Does anyone know if would it be possible to implement this as a hook when I upload images using a certain field?

Hi, horst!

After updating PW to the latest dev yesterday, i've getting this on pimLoad():

Hello everyone,

New to PW and modules etc, so this is a steep learning curve for me at the moment but enjoyable

Using the code below I am getting images to display without problem, now I would like to add a watermark to the images

  • I have installed the PageImageManipulator
  • Have read through the postings on using it but still confused

Is the watermark image stored in the images file or does it have to form part of a template and page?

I have made a template called watermark

  • Should I know make a page called template and upload an image into it?
  • How do I get the watermark to work with the code below

<?php
$images = $page->new_images_field;
foreach($images as $image){

  echo "<img src='{$image->url}' />";
  echo "<br><br><br>";

}

?>

Thank you - Mel

@Mel: here is a post that describes how to use a watermark that is uploaded into a single image field (to make an image field a single image field you have to setup the field to only allow 1 file, otherwise, 0 or greater 1 it is a multiple files field): https://processwire.com/talk/topic/4264-release-page-image-manipulator/#entry41883

The general how to you can read in the initial post here in this thread:

* 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:

The $pngAlphaImage can be a filename (full path and not an url!) or a pageimage.

Example with filename, assumed you have uploaded a png watermark image per FTP to your server into a directory besides wire and site, called "_mystuff":

$png = $_SERVER['DOCUMENT_ROOT'] . '/_mystuff/' . 'basename-of-my-watermark.png';

foreach($images as $image) {
    $watermarked_image = $image->pimLoad('tw', true)->width(500)->watermarkLogo($png, 'southeast', 0)->pimSave();
    echo "<img src='{$watermarked_image->url}' />";
}

An example with png from an imagefield, assumed it is called 'watermarkfield' and is on a page with the name/url '/tools/'. The tools page isn't visible from the frontpage, it is only a page that holds some fields and stuff that I need around the site on different places:

// assumed the watermarkfield is a single image field:
$png = $pages->get('/tools/')->watermarkfield;

// assumed the watermarkfield can have multiple images and I want use the first one:
$png = $pages->get('/tools/')->watermarkfield->first();

foreach($images as $image) {
    $watermarked_image = $image->pimLoad('tw', true)->width(500)->watermarkLogo($png, 'northwest', 0)->pimSave();
    echo "<img src='{$watermarked_image->url}' />";
}

Hello Horst,

Thank you for the instructions on how to use the watermarkLogo it works really well, I used the second example above using the tools page - which also taught me a bit more about how templates and pages interact with each other.

Thanks again - Mel

Hi Horst

Got a little problem.

I have just upgraded my server to apache 2.4 and, more importantly, php 5.5.9

On one dev site I am suddenly getting the following error - it was fine on the old server and older version of php:

Error: Call to undefined function imagecreatefromstring() (line 837 of /home/sanglier/public_html/site/modules/PageImageManipulator/ImageManipulator.class.php) 

What do you reckon?

@Joss: you should not use the PHP 5.5.9 - it has a buggy GD-lib, (if has a installed one  :P )

You should use one greater than 5.5.11!

You should run processdiagnostics when starting with new server setups. This one would have told you everything at once.

I'm trying to use this module to convert a bunch of png files to jpg. It works fine with a handful of images, but then it get's slower and slower. Here is my testing code:

$images = $page->images;

if ($images) {
	foreach ($images as $image) {
		$jpg = $image->pimLoad()->setOutputFormat('jpg')->pimSave();
	}
}

And here are the debug times in seconds - every number at the beginning of the line shows the loop count (it equals the number of images converted):

1: 0.21
2: 0.41
3: 0.67
4: 1.08
5: 1.96
6: 4.42
7: 12.79

In fact it's always the same image with a different name (1.png, 2.png and so on).

Anybody facing the same?

Hi horst - great module (I'm a bit late to the party ;)).

Here's an example using Apeisa's Thumbnails module - I had trouble with this because the thumbnail URL is relative to the homepage and therefore doesn't contain the whole server path to load the thumbnail with.

// First we get the thumbnail - replace thumbname with your thumbnail name as set in the Thumbnails module
$relativePath = $page->images->first()->getThumb('thumbname');
 
// Then we add the root path (note: will not work in a subdirectory - not sure about localhost either - you may have to hardcode this bit unless someone has an idea?
$fullPath = $config->paths->root . $relativePath;
 
// Now do your nice manipulations if the image doesn't already exist (we only want to convert it once)
if (!file_exists($fullPath)) {
    $modules->get('PageImageManipulator')->imLoad($fullPath, array('outputFormat'=>'jpg', 'targetFilename' => '$page->images->path . 'test.jpg'))->save();
}
 
echo "<img src='" . $page->images->url . "test.jpg' />

This was typed in the browser and my actual code is for a different scenario so this may require some modification!

EDIT: Of course, once you've generated the file once then you will want to check for that rather than keep recreating the file - modified my example to show this.

EDIT2: It would probably be a good idea if you are using this example to have a module that clears any existing test.jpg files on page save (or image changes but not sure how) for the relevant templates so that if someone changes the image the PIM runs again when the image is next viewed on the site.

Possible bug?

If I use it on a normal PageImage and use the targetFilename option, it creates a new file whenever the code is run, appending _1, _2 etc to the end of the targetFilename. If I run the same code without the targetFilename option it creates the file once and doesn't overwrite or create duplicates.

Basically I want to name my file in a specific way, but I don't want to create it each time or create duplicates - to achieve this I have to use the if (file_exists... code from my example in the previous post but I'm not sure I should need to?

@Pete: I'm not sure if I have updated the Pim after that post here: https://processwire.com/talk/topic/4264-release-page-image-manipulator/page-5#entry60648

possibly not. So best you do not pass your options with the class-init but with the ->setOptions($options) method or with individual methods ->setTargetfilename ->setOutputformat,

Can you test it and report back please?

@Pete: regarding your "test.jpg", you only need to build a name that matches the new naming conventions of PW core Pageimage. That way all is fine because PW will do the dishes for you.

It takes care of all image variations belonging to an original image. You only need to tell the system that this is a derivative image. :)

The naming scheme now is aware of suffixes. You simply can use the original filename and add a suffix to it. (in fact it isn't limited to only one suffix, it can have multiple of them). Following the original image is named basename.ext

If you want create one or more derivatives you should go with this scheme:

      basename.-suffix.ext

      basename.-suffix1-suffix2.ext

following i change your above example in a detailed manner:


// define suffix, and fileformat if needed
$suffix = 'yoursuffix';               // allowed are: a-z 0-9 and underscore !! not more!
$ext    = 'png';                      // your desired outputformat

$image = $page->images->first();      // get the image
$info  = pathinfo($image->filename);

$dir   = $info['dirname'];            // dir to the page assets/files/ folder
$name  = $info['filename'];           // basename without extension
$ext   = $info['extension'];          // only if you want use the same fileformat as the original is !!

// build the targetfilename and the URL
$targetFilename = $dir .'/'. $name .'-'. $suffix .'.'. $ext;

$targetURL = dirname($image->url) .'/'. $name .'-'. $suffix .'.'. $ext;

$sourceFilename = $dir .'/'. basename($image->getThumb('thumbname'));

// Now do your nice manipulations if the image doesn't already exist (we only want to convert it once)
if (!file_exists($targetFilename)) {
    $modules->get('PageImageManipulator')->imLoad($sourceFilename)->setOutputFormat($ext)->setTargetFilename($targetFilename)->save();
    // or this way
    $modules->get('PageImageManipulator')->imLoad($sourceFilename)->setOptions(array('outputFormat'=>$ext, 'targetFilename'=>$targetFilename))->save();
}
 
echo "<img src='{$targetURL}' />";

.

.

Additionally, if you use Pia to assist you while developing a site, your code should ask her if you are actually online and like to refresh all images:

// Now do your nice manipulations if the image doesn't already exist or if you (Pete) are actually online, testing something and want force recreate images
if (!file_exists($targetFilename) || true === $config->imageSizerOptions['forceNew']) {
...
I love it when a plan comes together!    a-team-240x300.jpg

Horst - I'm experiencing this at the moment and have found the solution.

I think the line in your module here is problematic:

$a = wire('modules')->get('ProcessCropImage')->getModuleInfo();

That line will run fine when you are logged into ProcessWire, but I think it somehow loads into memory the actual page using the ProcessCropImage process module which is only accessible by admins so doesn't work when viewing as a guest (that's the only crazy theory I have for now :)).

It's a tricky issue to track down, but basically replacing that whole block of code with this stops it from happening (essentially turning thumbnail boost off!):

// check if we can be used to boost the thumbnail module, - is it installed?
            if(true === ($this->thumbnailBoost = (bool)wire('modules')->isInstalled('ProcessCropImage'))) {
                // now check that at least the minimum version number of ProcessCropImage is installed:
                $needed = '1.0.2';
                //$a = wire('modules')->get('ProcessCropImage')->getModuleInfo();
                //$actual = preg_replace('/(\d)(?=\d)/', '$1.', str_pad("{$a['version']}", 3, "0", STR_PAD_LEFT));
                //$this->thumbnailBoost = version_compare($actual, $needed, '<') ? false : true;
                $this->thumbnailBoost = false;
            }

@Pete: thanks for tracking this down! ^-^

I have updated the module and changed the code by adding a check for the permission 'image-crop' here.

(this needs further investigation, here it is a quick solution to stop the error.)

If you can find some time, would you be so kind and test it if this work at your end?

Hi.

I've got some problems after creating an PIM image. I'm using PHP 5.5.19 and tried it on the current 2.5.2 and on the latest dev from this morning. Server is lightning.pw, so usual this setup doesn't make any problems. I'm using the default 2.5 image settings in the config.php

Task: First, resize the image to a given width, then grayscale() it and then overlay a transparent gradient.  Afterwards use it on different position in the HTML code. This is my function to create this image variation:

function getBrandImage($image,$width=1080,$prefix='branded') {
	if($image->name != '') {
	
	//$image->pimLoad($prefix)->removePimVariations();
	
	//Path to the overlay png depending on orientation
	$overlay_path = wire('config')->paths->templates . 'assets/overlay-landscape.png';
	
	if($image->width < $image->height) 
		$overlay_path = wire('config')->paths->templates . 'assets/overlay-vertical.png';
	
	//Output
	$o = array('outputFormat'=>'jpg');
	
	// apply it together with other actions
	$result = $image->pimLoad($prefix,true)->setOptions($o)->width($width)->grayscale()->watermarkLogoTiled($overlay_path)->pimSave();	
	
	}
	return $result;
}

It will create an image variation that has the desired effect. But now starts the weird stuff I can't figure out.

1) On my homepage, I'm calling this function with the default width of 1080 and I get back the PageImage. I now pass this PI to a simple function that renders and srcset html output by generating 3 variations of this image with the PW image functions.  This function works when I just pass a regular $page->image->size(120,120) PI object.

//Renders an image as srcset
function renderImage($image,$class='',$sizes='auto',$sets=array(400,767,1080,2120)) {
	$out = '';
	
	if($image->name != '') {
		if($class != '') $class = ' ' . $class;
		
		$o = array( 'upscaling' => true, 'cropping' => true, 'quality' => 40);
		
		//Start
		$out .= "<img src='{$image->width(260,0,$o)->url}' alt='{$image->description}' data-srcset='";
		foreach($sets as $s) {
			$img = $image->size($s,0)->url;
			$out .= "{$img} {$s}w, ";	
		}		
		$out = substr($out,0,-2);
		$out .= "' data-sizes='{$sizes}' class='lazyload{$class}'/>";
	}	

The $image here is the $result from the function above. It will create the first image in srcset (inside the foreach). The other images will output with 0x0 in the filename and are not created. 

2) On another page, where I need smaller images but only in 1 resolution, I'm calling the getBrandImage() function again but this time with width of 400. It will create the image but I think it crashes because the file permissions are set wrong, so the files can only be seen directly on a file level. 

I get the same results when I resize the image before I pass it to PIM or try different combinations.

When I just leave out the PIM stuff and create the image inside PIM with PW (and without the gradient/grayscale) everything works. That why I think this is an issue with PIM but I can't figure out anymore. The errrors.txt file doesn't show anyting. When I turn on debug, those messages appear. They don't appear when I comment out the PIM part.

Hi Philipp,

ähm, may I say that this sounds confusing? :)

It will create an image variation that has the desired effect. But now starts the weird stuff I can't figure out.

You only need to double check here if it returns a valid pageimage and has created the derivative file. If both is yes, PiM has done it work successful.

If you further do not call PiM anymore, it has nothing to do with PiM! - Ready!

-------------------------------

Looking at your code:

$out .= "<img src='{$image->width(260,0,$o)->url}'

What is width 260, 0, $o ?

You have done the same things wrong like in earlier posts. Passing a zero as second option to width, what should be an array with options! Ryan has changed pageimage::size to silently fail with this instead of crashing the process. This was a wish by yourself!

Another thing is that you has run into timeouts with imagesizer in the past. I have posted a solution to you and maybe over 10 times more here in the forums: include a set_time_limit() in every loop that calls imagesizer. ( foreach($sets as $s)!

There are two options for the set_time_limit() now: please add it into your loops or only use PW >= 2.5.10 in the future, because PW since 2.5.10 has an own set_time_limit() call in ImageSizer! :)

Thanks for the answer. If I replace the single line where I call PIM

$result = $image->pimLoad(....)->pimSave()

with

$result = $image->size(123,123) 

all the following functions and stuff works. Yes, you've found a bug/problem in the rest of my code (thanks), but my question is, why does it totally fail with the PI object from PIM and not with the one from PWire? I rewrite all those image stuff this evening and try again.

I'm using the latest dev build (2.5.10 the latest version on the dev branch as of yesterday 18:00 GMT time) and the time limit is 60 seconds. A try with 120seconds did also fail (with a single image at 2000x1333). Memory limit is 128M.

_

I never requested it fo fail silently. The problem was, that an error a developer could made in the past and that is now fixed, affects all future operations with an image because a half-way created image exists on the file system.

Hhm, it wasn't clear to me that you have encountered differences between Pageimages derived from Pageimage or derived from PiM. (or I may have overlooked it in all that examples)
 
I think it would have avoided some confusion if you just have asked / told that the objects behave different, without (partly wrong) code and lots of error messages.
 
You are also speaking about filenames generated with .0x0 in its name.?! Pageimage::size generates the filenames before any manipulatiuon through ImageSizer and only according the passed values for width and height. So, at that point you may check what values you are passing to the functions.

------

But lets focus on that objects thing:

I will try to replicate and compare that. Just to clarify a few things:

  • You have checked that after your PiM call a Pageimage Object is returned?
  • Have you tried it with a PiM that does other manipulations, maybe just pimLoad()->pimSave(). Does it behave the same or is it different?

Pim generates the PageimageObjects this way: https://github.com/horst-n/PageImageManipulator/blob/master/ImageManipulator.class.php#L751
It looks the same like Pageimage::size does it: https://github.com/ryancramerdesign/ProcessWire/blob/dev/wire/core/Pageimage.php#L316

 
So, we need to compare the objects, first try with simple objects that only should differ in the name:

$size = $image->size($image->width, $image->height);

$pim = $image->pimLoad('test')->pimSave();

And then with a manipulated one from your example.

------
 

I never requested it fo fail silently. The problem was, that an error a developer could made in the past and that is now fixed, affects all future operations with an image because a half-way created image exists on the file system.


Ah, ok! Sorry for remember me wrong!

Finally found time so rewrite the thing. In short, it is now working but I can't figure out what didn't work before.

1) My $size was set to 0. This was my mistake. The width() options just ignored the $options array.

2) I manually removed all pages including the image files and re-upload them. This made PIM PageImage objects work as well as the ProcessWire ones.

Sorry, this seems like a fault on my side. PIM works fine once you get the things around right.

Horst, thanks a lot for this wonderful module. It is extremely useful to me and I'm impressed by its complex possibilities!

I've got a question regarding the caching and rendering: While regular images are cached, those images I process using PageImage Manipulator seem to be recreated on every access of the frontend page containing the image.

Is this a desired behaviour, or did I just miss setting the right parameters?

Here's the code used in my template to output an image with added watermark on the website:

        $img = $page->special_image;

        // choose file containing watermark sample
        $watermark = $pages->get("/special/watermark")->images->first();

        // add watermark to image
        $imagewithwatermark = $img->pimLoad('tw',true)->width(800)->watermarkLogoTiled($watermark->filename)->pimSave();

		// output image
        $content .= '<img src="'.$imagewithwatermark->url.'" title="'.$page->title.'" style="height: '.$imagewithwatermark->height.'px; width: '.$imagewithwatermark->width.'px;" /><br />';

      You can also enable the support for respecting the Do-Not-Track (DNT) header to don't annoy users, who already decided for all their browsing experience.
      Currently there are four possible cookie groups:
      - Necessary (always enabled)
      - Functional
      - Statistics
      - Marketing
      - External Media
      All groups can be renamed, so feel free to use other cookie group names. I just haven't found a way to implement a "repeater like" field as configurable module field ...
      When you want to load specific scripts ( like Google Analytics, Google Maps, ...) only after the user's content to this specific category of cookies, just use the following script syntax:
      <script type="text/plain" data-type="text/javascript" data-category="statistics" data-src="/path/to/your/statistic/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing" data-src="/path/to/your/mareketing/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="external_media" data-src="/path/to/your/external-media/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing">console.log("Inline scripts are also working!");</script> The data-attributes (data-type and data-category) are required to get recognized by PrivacyWire. the data-attributes are giving hints, how the script shall be loaded, if the data-category is within the cookie consents of the user. These scripts are loaded asynchronously after the user made the decision.
      If you want to give the users the possibility to change their consent, you can use the following Textformatter:
      [[privacywire-choose-cookies]] It's planned to add also other Textformatters to opt-out of specific cookie groups or delete the whole consent cookie.
      You can also add a custom link to output the banner again with a link / button with following class:
      <a href="#" class="privacywire-show-options">Show Cookie Options</a> <button class="privacywire-show-options">Show Cookie Options</button>  
      I would love to hear your feedback 🙂

      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.
      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 module both in the module directory and via github:

      If your module has a lot of config fields you might want to divide them into groups inside a tabbed interface. Here is a demonstration module showing how this can be done.

      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. Fluency can be used by users having roles given the fluency-translate 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.

      An inputfield module that brings EasyMDE Markdown editor to ProcessWire.
      EasyMDE is a fork of SimpleMDE, for which there is an existing PW module. Inputfield EasyMDE has a few advantages though:
      EasyMDE seems to be more actively developed than SimpleMDE, which hasn't seen any updates for several years. You can define options for Inputfield EasyMDE. Inputfield EasyMDE can be used in Repeater fields and in custom fields for File/Image fields.  
      Inputfield EasyMDE
      EasyMDE (Easy Markdown Editor) as an inputfield for ProcessWire.
      EasyMDE is a Markdown editor with some nice features, allowing users who may be less experienced with Markdown to use familiar toolbar buttons and shortcuts. More information is at the EasyMDE website.

      Installation
      Install the Inputfield EasyMDE module.
      Usage
      Create a new textarea field, and in the "Inputfield Type" dropdown choose "EasyMDE". Save the field and if you like you can then configure the EasyMDE options for the field as described below.
      To convert Markdown to HTML you can install the core TextformatterMarkdownExtra module and apply the textformatter to the field. Alternatively you can use $sanitizer->entitiesMarkdown() on the field value, e.g.
      echo $sanitizer->entitiesMarkdown($page->your_field_name, ['fullMarkdown' => true]); Configuration
      On the "Input" tab of the field settings you can define EasyMDE options for the field in JSON format. Refer to the EasyMDE documentation for the available options. Keys in the JSON must be surrounded with double quotes.
      Example:
      "toolbar": ["bold", "italic", "heading", "|", "side-by-side"], "sideBySideFullscreen": false
