If I want to write a transparent bit map and, for this, I use TImageList
in this mode:
TempList := TImageList.CreateSize(Picture.Width, Picture.Height);
Try
TempList.AddMasked(Picture1, TransColor);
TempList.Draw(BCanvas.Canvas, X, Y, 0, Enabled);
finally
TempList.Free;
end;
Where Picture is the source BitMap, BCanvas is the destination bit map
and Picture1 is a support bitmap, during the execution of the line
TempList.Draw(BCanvas.Canvas, X, Y, 0, Enabled); i have an error like
this "External: SIGSEVG"
Bye,
David
