Hi,
the scripts converts small bitmaps to gtk3 css gradient definitions - direction at the moment only from bottom to top.

Please downsize the icon before to 10 px heigth and remove border.

USAGE:
bash png2css yourimage.png> yourimage; bash yourimage > yourimage.css; rm yourimage; rm y.txt

Perhaps someone could add something to do automatic downsize.

requires awk imagemagick bash cat identify

Why this script ? to speed up development of gtk3 themes.

Do try to get the images gradient with gimp. Its an unexact and time intensive task.

Why no screenshot? well its an script.
