## Description

Extend the REST-API to work with WordPress Media-Library. Organize images in Folders.
Add and Update images including Metadata and Posts using the images. Access with
Authorization only.
 This plugin extends the REST-API of WordPress to directly access
the Media-Library for Images. It is intended to be used together with a Lightroom
Plugin or as a stand-alone interface for headless WordPress. The new REST-API endpoints(
functions) allow to add additional metadata to images, update existing metadata 
or update images completely without changing the WordPress-ID. Images may be added
to the standard directory hierarchy of wordpress or to an additional folder which
allows better organization and searching for images. NEW FUNCTION : See 3.2

## Installation

 1. Visit the plugins page on your Admin-page and click ‘Add New’
 2. Search for ‘wp_wpcat_json_rest’, or ‘JSON’ and ‘REST’
 3. Once found, click on ‘Install’
 4. Go to the plugins page and activate the plugin
 5. Go to Admin Settings and activate what you prefer.

 * PHP-Compatibility check with phpcs. Compatible from PHP 5.4 – 8.0. But keep PHP

#### 0.0.14

 * Readme and docblocks updated.
 * Added functionality to handle webp images as well. Tested with WP 5.8-RC4 test
   version.

#### 0.0.15

 * Update function updated! The update includes now also ALL posts that are using
   the updated image. All links are changed to the new links.
 * The plugin is partly re-using the great work of ‘Enable Media Replacer’ that 
   solved the task already for manual updates via the frontend.
 * Aditionally the ‘alt-text’ and the ‘caption’ are updated if the are used in gutenberg
   blocks ‘image’, ‘gallery’ and ‘media-with-text’.
 * Important: There are many, many other blocks, images, galleries around. For these
   I couldn’t realize the update of ‘alt-text’ and ‘caption’.
 * BUT: The links are updated!
 * Code quality check with phpstan: level 5 is OK except 19 remaining Errors. These
   were carefully checked and regarded as OK. Minor changes to reach level 5.

   successfully tested.

*Code-Rework:
 * loaded updated emrFile.php from github * split helper functions
in several files and renamed /inc to /includes * simplified loading of WP-Error 
class * added a programatical filter for image quality. Standard is now 80 for jpeg
and 40 for webp. * tested the whole bunch of changes with the python-test-suite 
and Lightroom. * The further code rework acc. to: https://carlalexander.ca/designing-
system-wordpress-rest-api-endpoints/ or * https://torquemag.io/2018/03/advanced-
oop-wordpress-customizing-rest-api-endpoints-improve-wordpress-search/ looks very
promising but won’t be done.

#### 0.0.19

 * Rework of the image update function (endpoint of POST-Request /update/): The 
   function updates the image FILE only and the filename if provided in POST request.
 * Content, description, alt-text, parent ASO are now kept and no longer overwritten.
 * Change the modified date, only and not the published date on changes. Valid for
   image and post that uses it.
 * Set the slug and permalink according to title, if the title is changed.
 * If the title of the old image was different from the filename than title will
   be kept. All other meta-data remains unchanged including post-parent.

   quality for image resizing. Increased minimum versions of WP and PHP.

#### 1.1.0

 * EXPERIMENTAL !!!
 * Added an own class to generate the image-sizes with ImageMagick. This produces
   smaller files as expected where AVIF is 0.5 Jpeg-size and -30% of WebP-size.
 * The calculation times are roughly:
 * JPEG : 2.0 s, WEBP : 3.0 s, AVIF : 4.8 s on my local machine. Without my Image_Editor
   its 2.6s for AVIF only! Tested with 1 image only!

   is used always! For every upload!
 * Added new routes and functions to handle local generated images.

#### 2.0.0

 * Updated minimum PHP-Version to 8.0 (8.3 would be even better)
 * Updated method doMetaReplaceQuery() in replacer.php as start of update to new
   WP and PHP principles. (Old code works but is very old fashioned)

 * Update method doMetaReplaceQuery in replacer.php. Used Copilot to review and 
   update replacer.php for PHPStan Level 8.
 * Added a new hook for the standard media upload to have Metadata for webp and 
   avif identical to jpg. Rework of Metadata Extractor.
 * Rework of ‘trigger_after_rest’ for PHPStan Level 8 and removed the update of 
   the slug in title change. Implemented the usage of the new setting to update 
   content with caption and title.
 * BREAKING CHANGE: Minimum PHP is now 8.x. Minor Updates in almost all PHP-Files.
 * Added simple Admin Settings page mainly for the new Hook (AdminSettings.php.)
   and some for the existing REST-API.
 * Test with WP 7.0
 * Rebranding: Plugin renamed to “Media Library Extension”
