Thanks so much for your article on installing Imagick for PHP7 on Windows 10. I used it for Windows 7 and it worked a charm with one small oddity. I kept getting the CLI has stopped working message. A debug of actual ImageMagick showed that it was trying to open a delegates.xml file in the ImageMagick directory that didn’t exist. WordPress supports both ImageMagic and GD Library for PHP image processing extensions to resize and crop images in your website. By default WordPress will try to use ImageMagick. If it is not available or it doesn’t support the requested mime-type, WordPress will use GD extension. . This is a WordPress specific implementation of Imagick::thumbnailImage,. which resizes an image to given dimensions and removes any associated profiles. WordPress Image Editor Class for Image Manipulation through Imagick PHP Module. /. Efficiently resize the current image. This is a WordPress specific.

WP_Image_Editor is an abstract class, so it can’t be called directly. It is used for implementations like WP_Image_Editor_GD and WP_Image_Editor_Imagick. It has some base functionality that can be used by those implementations.

You shouldn’t call an implementation directly. Instead, use wp_get_image_editor(), which looks at which implementation is the best.

• Quick & easy to use: Install, activate, configure and start uploading new media images!
  To (re)compress existing media images use “Regenerate Thumbnails Plugin” or “WP CLI media regenerate” command.

• New in 1.3.13 – “Full size Compressed”.
  Original file will be compressed to ‘filename’-(Width)x(Height).’ext’. Original image remains unchanged. Due to PHP-imagick resource limits, only if upload/original is not larger than 2500×2500 pixels.

• New in 1.3.13 – “Sharpen JPEG Image”.
  Dual setting to sharpen full-size and thumbnail/sizes JPEG images.

• New in 1.3.13 – “Transparent WebP”.
  Both transparent and opaque PNG images are converted to Webp.

• After activation, only settings you maybe want to change is JPEG Compression Quality and SharpenImage Sigma.
  Choose your compression quality from 30% to 95%. Sharpen Image from 0.5 to 1.5 Sigma. For the rest of the settings, use defaults or feel free to experiment and have fun with. 😇

• Automatic image optimization to thumbnails and conversion to WebP clones:
  No limits in number or size of images. No external service required. Compress better or keep higher image quality than WordPress does by default. Images will be automatically compressed on upload or on “regenerate thumbnails”. Uploaded image is always preserved in original state. Image Compression will always start from original image quality. You can’t “overoptimize”. Reoptimize existing images with “Regenerate Thumbnails plugin” single or batch process, or with “WP CLI media regenerate” command.

• Compatible with “WP CLI media regenerate” command and/or with “Regenerate Thumbnails” plugin.
  Important Note: Since WordPress 5.3, BIG JPEG images reduced to 2560×2560 (by “Big Image Size Threshold” feature) and then manually edited by user, on regenerate, will be restored back to original (unedited) version. User edited modifications will be lost. See GitHub issue. Same bug/issue applies both to “WP CLI media regenerate” command and “Regenerate Thumbnails plugin”. To fix that bug/issue, install or upgrade Warp iMagick plugin to version 1.3.13 or above.

• Compatible up to PHP 7.4.9 and tested against coding standards.
  Tested with PHP_CodeSniffer (phpcs) using WordPress Coding StandardsGitHub rules and PHPCompatibility rules.

• Improve your site performance, Google PageSpeed score and SEO ranking when serving better compressed JPEG/PNG or WebP images.
  Every JPEG and every non-transparent PNG media image or thumbnail found during image optimization process is converted to WebP and saved as copy with .webp extension added. Default PNG&JPEG to WebP images compression quality is 75% (configurable). In addition, JPEG to WebP compression quality can be set to use & follow compression quality set for JPEG images.

• WebP Delivery Note
  Due to variety of hosting server software, cache pugins or CDN used, this plugin even does not try to automagically configure your server to deliver WebP images. You will find instructions on how to configure server and deliver WebP images on the settings page. Click on HELP at the top right of the plugin SETTINGS PAGE. Serving WebP images requires manual (DIY) configuration of Apache .htaccess file or NGinx configuration & restart, or IIS or LiteSpeed …

• Warp-iMagick – Image Optimizer gives you full control over images, file size and quality in image optimization process.
  Images optimization is customizable with advanced image compression settings. See the plenty of options used to optimize images in the Features section below.

• Multisite support
  Designed to work on WP multisite. No known reason to fail on WP multisite, but not extensively tested yet!

• Clean uninstall
  By default, no plugin settings are left in your database after uninstall. Feel free to install and activate to make a trial. However, you can choose to preserve plugin options after uninstall. For detailed uninstall info related to added WebP images, see the FAQ section below.

• Privacy
  Warp-iMagick plugin does not collect nor send any personally identifiable data from your server. WordPress builtin cookies are used to store admin-settings page-state.

• Known conflicts
  Due to use of bfi_thumb library which completely takes over wordpress WP_Image_Editor classes, in Ajax Search Lite plugin and in Circles Gallery plugin, Warp iMagick plugin will fail to activate while those plugins are active. Activating those plugins after Warp iMagick may cause malfunction of Warp iMagick.

سوالات متداول

1. PHP-Imagick to compress JPEG/PNG files (required).
2. PHP-GD for WebP files (optional, but usually installed).

In order to modify/resize/crop photos or images, WordPress requires at least PHP-GD. When both extensions are installed, WordPress prefers PHP-Imagick over PHP-GD.

1. WordPress 5.2 and above: Administrator: Menu -> Tools -> Site Health -> Info -> Expand “Media Handling” and check if “ImageMagick version string” and “GD version” have values.
2. WordPress 5.1 and below: Install Health Check & Troubleshooting plugin. Open “Health Check” plugin page and click on “PHP Information” tab. You will find there all PHP extensions installed and enabled. Search (Ctrl-F) on page for “Imagick” and “GD”.
3. WordPress Editor class must be WP_Image_Editor_Imagick (or Warp_Image_Editor_Imagick) but NOT WP_Image_Editor_GD.
4. PHP-Imagick extension must be linked with ImageMagick library version 6.3.2 or newer.
5. PHP-GD extension version must be at least 2.0.0 to be accepted by WordPress Image Editor.

1. WPEngine: Both by default.
2. EasyWP: Both by default.
3. DreamHost: By configuration.
4. SiteGround: Must enable.
5. Ask your host-service provider.

Wordpress Imagick Vs Gd

1. Debian/Ubuntu: “apt-get install php-imagick”.
2. Fedora/CentOs: “yum install php-imagick”.
3. Ask your host-service provider.

See the settings page HELP for instructions on how to configure server to redirect .jpg/.png to .jpg.webp/.png.webp, if such file exists and browser suports WebP image format.

To prevent overwriting duplicate “WebP” files. With single extension, when you upload “image.png” and “image.jpg”, second “image.webp” would overwrite previous one.

Because your server has no PHP-GD graphic editing extension or your PHP-GD extension has no WebP support.

1. Existing images remain optimized. If you run “Regenerate Thumbnails” batch process, after plugin is deactivated or deleted, batch process will restore original file-size and quality of WordPress thumbnails.
2. If you have WebP images, they won’t be deleted. You can delete all WebP images while plugin is active. To delete WebP images, disable WebP option and then batch-run “Regenerate Thumbnails” for all media images.

Because your server has no PHP-Imagick installed or has too old version of PHP-Imagick.
