Subject: From Tiff to Bmp


I just purchased this component and started to make my first application with it which coverts Tiff image to Bmp.

How do I use that SaveToStream function correctly? I keep getting access violations no matter what I do. SaveToStream requires that the file format is registered with RegisterDibGraphic function, right? But the third parameter is a mystery to me. What do I have to put in the third parameter?

I believe that this code is enough to use SaveToStream:

TImageScrollBox *t = new TImageScrollBox(this);
t->LoadFromFile("image2.tif", 1);
RegisterDibGraphic("bmp", "Bitmap image", ???);
t->SaveToStream(stream, "bmp");
delete t;

Is this code correct and what do I have to put in the third parameter (replaced here with ???) of RegisterDibGraphic function? Correct if I'm wrong.

Thank you in advance,
