Subject: Re: Have TBitmap, want TBitmapGraphic (and others)
In reply to: Jarle Stabell 's message, "Have TBitmap, want TBitmapGraphic (and others)" on 17:18:10 03/26/00 Sun


Dear Jarle,

I have a feeling this is palette related. Is your source bitmap 16 or 256 colors? I would appreciate if you could try this,

l_bitmap.PixelFormat := pf24bit;

Just before,

l_bmpGraphic.Assign(l_bitmap);

and let me know if that still has the same behavior.

Best regards,

Michel
