I am working on image processing library in c#. want to improve performance/speed and better memory management. I am using Bitmap class and its just array manipulations. Can someone suggest me, how to improve it. any guidelines?
The first thing to do is to find out where your problem lies. I would suggest using the built-in Visual Studio profiler to figure out where your execution performance bottlenecks are.
There's an MSDN article here that explains how to use the profiler.
