imgtools

Imgtools provides functionality that is missing in Tk, most notably the ability to rotate images and to scale images by any factor.

Source tarball and a few precompiled Tcl Modules are available at: tkimgtools.sourceforge.net

Features

  • Scale images
  • Rotate images
  • Manipulate alpha channel
  • Get transparency information from an image
  • Apply a transparency mask to an image
  • Three interpolation methods: nearest neighbor, linear and bicubic (the Catmull-Rom flavor)
  • Create linear color gradients
