%description
This module implements several resizing algorithms with a focus on low
overhead, speed and minimal features. Algorithms available are:

GD's copyResampled (floating-point)
  GD's copyResampled fixed-point (useful on embedded devices/NAS devices)
  GraphicsMagick's assortment of resize filters (floating-point)
  GraphicsMagick's Triangle filter in fixed-point

Supported image formats include JPEG, GIF, PNG, and BMP for input, and JPEG
and PNG for output.

This module came about because we needed to improve the very slow
performance of floating-point resizing algorithms on platforms without a
floating-point unit, such as ARM devices like the SheevaPlug, and the
Sparc-based ReadyNAS Duo. Previously it would take many seconds to resize
using GD on the ReadyNAS but the conversion to fixed-point with a little
assembly code brings this down to the range of well under 1 second.

GD is also incredibly difficult to build on platforms such as Windows so we
needed a replacement.

Normal platforms will also see improvement, by removing all of the GD
overhead this version of copyResampled is around 3 times faster while also
using less memory.

The fixed-point versions have an accuracy to around 4 decimal places so the
quality of floating-point vs. fixed is essentially identical.
