gimp-texturize - 2.2-4+b1 main

Gimp-texturize is a plug-in for the GIMP, a famous picture editor and
manipulator.
.
A few images are designed to be copy-pasted one next to another and still
look natural, but the result is usually periodic and very monotonous. The
Texturize plugin allows you to have a realistic pseudo-periodicity.

After install, the plugin will be available at Filters > Map > Texturize.
