Crop-Thumbnails

• The plugin will only crop image-sizes where crop is set to “true” (hard crop mode – see: https://codex.wordpress.org/Function_Reference/add_image_size).
• If you had set one image dimension in add_image_size() to “0“, the plugin will crop it in the ratio of the original image.
• If you had set one image dimension in add_image_size() to “9999“, the plugin will change the 9999 to the actual size of the current original image.
• You are able to crop all images with the same ratio at once (default) or and any imagesize (and ratio) seperate.

The “Adavanced Custom Fields” plugin has a functionality to add images to taxonomies. To add cropping functionality on these images you have to add a small code-snippet to your functions.php
Have a look on the github readme-page for details.

If you had viewed your image on the site before, your browser has cached the image. You can hard refresh the page by hitting:
* “CTRL + F5” (on Windows)
* “Apple + R” or “command + R” (on Mac/Apple)

No. The purpose of this plugin is to provide control for the wordpress automatic crop. If you want to crop let’s say the full-size image you should

• a) upload it in a better format in the first place
• OR b) use the Standard WordPress-Image editor to crop the image.

A documentation with a list of all actions and filters can be found on the Github page of the project.

You can add the following filter in the functions.php of your theme to adjust the ratio of one or more specified image-sizes.
CAUTION: use only when the ratios are really close.

add_filter( 'crop_thumbnails_editor_printratio', 'my_crop_thumbnails_editor_printratio', 10, 2); function my_crop_thumbnails_editor_printratio( $printRatio, $imageSizeName) {     if($imageSizeName === 'strange-image-ratio') {         $printRatio = '4:3';//do override ratio     }     return $printRatio; } 

Yeah, there is a way. After the crop-thumbnails-modal closed it triggeres a javascript event on the body element. You could use jQuery to cache-break your cropped thumbnail (in backend-view).
The event called “cropThumbnailModalClosed”. The plugin also provides a global function that could be called (only in post-edit-view and mediathek) to do the cache-break.
Example-Code:

$('body').on('cropThumbnailModalClosed',function() {     CROP_THUMBNAILS_DO_CACHE_BREAK( $('.your-image-selector') ); });

Fantastic, i published the code on github. But be warned, i am carefully evaluate new features.

If you fork and planning to publish the forked plugin, please contact me.
