细节
Resizing can be done using PHP's internal image libraries, or using ImageMagick or another third-party converter, e.g. GraphicMagick.
These latter converters support more file formats than PHP, which only supports PNG, GIF, JPG, XBM and WBMP.
Set $wgUseImageMagick to true to use ImageMagick instead of the builtin functions.
For more information on how to set up ImageMagick, see Manual:Image administration#Image thumbnailing.

To fine-tune the output of ImageMagick, set $wgSharpenParameter and $wgSharpenReductionThreshold.
$wgJpegPixelFormat sets YUV chroma subsampling mode for JPEG thumbnails to reduce file size.
Some old MediaWiki installations may have $wgUseImageResize set to false.
ImageMagick requires that this setting be set to true, or else it will not work.
