GID Release 013

  • Quality of progressive JPEG and overall performance of JPEG decoding have been improved.
  • There are also two new tools shipped with GID (and of course using it):
    • comp_img: an image comparison tool (result is from 0: identical, to 1: black/white)
    • benchmark: a performance test between GID and ImageMagick, an open-source library. Test images are incorporated in the repository and the .zip release files. Some results: GID is significantly faster than ImageMagick for the GIF and PNG formats! More details here.

GID Release 06

Minor issues were fixed:

  • TGA: transparency hint correctly detected
  • GIF: workaround for an encoding bug in some animated GIF's

In the "tools" area, we've added two image processing examples:

  • Recurve, a tool for retrieving sets of (x,y) points from several curves plotted on a chart
  • Is_opaque, a tool for determining whether an image is fully opaque (not a single pixel with transparency), or not
