How does aurigma handle garbage collection? Under .NET anytime you use an unmanaged resource, like a handle or a file, you should call the Dispose() function to release the memory for the object. This help the GC but giving it less to do. I was wonder why the BitmapClass object doesn't have a Dispose() method. Is it implemented privately and taken care of that way? Thanks, Brian Fluid Media

BitmapClass is not written by us, it was generated by tlbimp utility. So it is not our fault that wrapper does not have a destructor method. :) I think the absence of this method was made with Microsoft by design. COM components has different cleaning mechanism and forcing destroying of the object may be unsafe if this component is used somewhere else. So if you need to reduce memory load the only think you can do is to use Unload method to free raster data (the most heavy block of memory) and endure that all the rest object remains in memory. You also should try to avoid creating bitmaps more than it is necessary. For example do not create bitmap objects in loop. Instead of that create bitmap outside of loop and call LoadFromFile inside loop, etc. Hope this helps.
