I think I posted about this about 4 or 5 months ago and I think someone applied a patch, but it seems this bug is back.
When 1 bitmap which is say 24bit, is assigned to another bitmap which is say 32bit, the second bitmap seems to preserve its 32bitness, when it should not, because an assign has taken place. The following example illustrates the issue... var thebitmap : TBitmap; undoimg : TBitmap; begin thebitmap := TBitmap.Create; thebitmap.PixelFormat := pf24bit; // definitely 24bit undoimg := TBitmap.Create; // default bit depth undoimg.Assign(thebitmap); //undoimg is now not 24bit! it is whatever the default is when a new Bitmap is constructed. end; I can submit this as another bug report, if necessary. This was tested in Mac OS X 10.5.8, using Lazarus revision 22631.
