hello,
I am trying to better my bitmap scanning code and cant seem to find a solution to do it. Right now I am using unsafe code (C#) to accompolish this and its not working out.
What I want is to be able to compare two bitmaps and it return the differences. Not as a whole bitmap, but by region. Right now I scan 128x96 regions of the bitmap, if its not the same it clones it and saves it then moves to the next 128x96 region. its just slow..
I looked at one dll that was written in VC6 and tried to port it over to C++.Net but couldnt seem to successfully pass the BYTE [] from the dll to my code after I compiled.
Does anyone here have any code that can scan a bitmap region by region for changes, and it be fast? The dll I looked at was using ASM to grab changes. Wish C# would do that.
Any help or information would be appreciated.
