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
