VideoLab GaussianBlur filter

[jh_]

I am trying to apply GaussianBlur filter on bitmap, like:

Bitmap bmDest = gaussianBlur1.ProcessBitmap(bmSource);

where bmSource is a bitmap with pixel format Format32bppRgb.

All I get, is the exception "Attempted to read or write protected memory."

When testing for example with MorphFilter instead of GaussianBlur, it works correctly inside the same program code.


What might I do wrong?
Thank for any help,
