Resizer is an extra by jgrant, first released on 2019-09-15.

Package Description

[Requires PHP 5.3.2 or higher]

Resizer is a PHP class for use within snippets.  If you're not developing your own snippet what you probably want is not Resizer by itself, but a higher-level package which uses it, like pThumb.

See the GitHub page for documentation, bugs, feature requests and all that.

Resizer implements a subset of phpThumb's options, at the moment mostly those relating to sizing and cropping.

Advantages to phpThumb / modPhpThumb

  • Considerably faster.  In a test of zoom cropping I found it to be 56% faster than modPhpThumb while using only 39% of the memory.
  • All zc options work even with GD.
  • The wl, hl, wp, hp, ws, hs dimension parameters work properly.
  • Doesn't have problems finding and using Imagick. It's not uncommon that phpThumb won't use ImageMagick even though it's installed.
  • Will use Gmagick if available.
  • Offers a few new options, like scale and variable quality.


  • Only supports a subset of phpThumb's functionality.
  • Requires PHP 5.3 or higher.
  • Doesn't work with the command-line version of ImageMagick, only the PHP extension.
