內容簡介
his plugin automatically generates a thumbnail for PDF files when they are uploaded to the WordPress Media library. It can also generate missing thumbnails or regenerate all thumbnails for old PDF files in the library. The Imagick library must be installed on the server for the plugin to function.
The plugin works on all types of WordPress installations, including domain, subdomain, subdirectory, and multisite/network, and is compatible with Apache and NGiNX servers. Users can set the maximum width, maximum height, image quality, and image file type of the PDF thumbnail.
The plugin also includes several shortcodes and functions that return information about the PDF thumbnail, such as the URL, path, image source, and image tag. Users can also use hooks to change the global PDF thumbnail settings for specific files.
