In reply to: Alain 's message, "Double buffering and tiling" on 23:49:45 08/03/05 Wed


Hello Alain,

There is no double buffering, but on the later versions of Windows, the TImageScrollBox is very smooth when panning. Try the Demo.Dpr project and see how it goes.

There no "tiling" where a large image is broken down into smaller images for display purposes. This would involve major changes to the TImageScrollBox. I have successfully loaded images 15000x15000+ plus, on Windows 2000/XP.

Best regards,

Michel
