The VipsScaler extension creates JPG and PNG thumbnails faster and at low memory usage. The extension replaces MediaWiki core's Media handlers for bitmaps, which default to ImageMagick. It is powered by the free image processing software VIPS, which speeds up resizing of large PNGs, and it improves the appearance of shrunken JPEGs.

The extension shells out to the VIPS binary. By configuring $wgVipsOptions, it can be configured to scale only certain files (for example, big PNG files).

Yapılandırma

$wgVipsCommand

Path to the "vips" command (default: /usr/bin/vips).

$wgVipsOptions

Options and conditions to scale images with this scaler (default: empty). Set to an array of arrays. The inner array contains a condition array, which contains a list of conditions the image should pass for it to be scaled with VIPS. Conditions are mimeType, minArea, maxArea, minShrinkFactor, maxShrinkFactor. The other items in the array are options. Options available are:

• sharpen - Set to an array with keys 'radius' and 'sigma', parameters to the Gaussian sharpen matrix.
• preconvert - Convert the file to a .v file first, which costs some space but saves memory on the actual downsize
• bilinear - Use im_resize_linear instead of im_shrink
• convolution - Apply specified convolution matrix
• setcomment - Add an EXIF comment specifying the source of the file. Requires $wgExiv2Command to be set properly.

Example

$wgVipsOptions = [
  // Sharpen jpeg files which are shrunk more than 1.2
  [
    'conditions' => [
      'mimeType' => 'image/jpeg',
      'minShrinkFactor' => 1.2,
    ],
    'sharpen' => [
      'radius' => 0,
      'sigma' => 0.8
    ],
  ],
  // Other jpeg files
  [
    'conditions' =>[
      'mimeType' => 'image/jpeg',
    ],
    'sharpen' => false,
    'bilinear' => true,
  ],
  // Do a simple shrink for PNGs
  [
    'conditions' => [
      'mimeType' => 'image/png',
    ],
  ],
];

$wgVipsExposeTestPage

Allow testing via "Special:VipsTest", which lets you verify it is working and see the difference in output quality. (default: false).
