Picture manipulation with GS

Tue May 23 16:23:59 CEST 2006


I am interested in knowing if it is possible to pull in the information from a bitmap, manipulate the information, and display the new bitmap.  

My goal is to take an arbitrary bitmap, read it in, pull the last line of information out of the bitmap, shift all the other rows down by one, and place the previous last line at the top of the bitmap.  This would be placed in a loop and the picture would look like it was wrapping as it scrolled.  

I would appreciate any suggestions for being able to perform this function strictly in erlang and not having to depend on any C (or other) APIs.
