Gaussian DropShadow

Post by stOrM! »

Well I hope I'm right here to ask a special question because of a feature I've seen in XNView.

As I could see the thumbnails are drawn with a really nice gaussian dropshadow.

While I'm writing a small Application currently, so I would like to know how I could implement this nice feature.

Do you use a special component to draw the thumbs with dropshadow or is it a procedure which draws the shadow?

btw.
I'm writing my Application using Delphi7 Enterprise Enviroment...

kindest regards
s!

Hi

Does anyone have an example of how to use gflDropShadow? Prefer Delphi, but other languages ok. I have tried, but get "access violation". Is it allowed to have dst-bitmap set to NIL, like for gflRotate?
