Jpeg Rotation

[Indodokhazi]

I am looking for any ideas, suggestions or code which can enable me to load a JPEG, then rotate it on the fly (ie must not save to rotate). The JPEG are very large hi-res images, so the code(control etc) must be very efficient at rotation. I have come acrosss one bit of code which sort of rotates but was way too slow to be of any use. If any knows of a such code or has any ideas, your help would be most appreciated. (I could maybe include an ack of your contribution in the app!)

Thnx Indodo.

Go to
http://www.planet-source-code.com/xq...HallOfFame.htm

and get the Advanced Graphics Routines DLL. It contains functions for fast rotation (with antialiasing) and many ohter image processing tasks. It is a real gem. You can have a peek into the source code (sadly, it is only partial), to see how the stuff is really working.

PS. The page takes quite some time for loading. You can stop midway, because it is at the very top.
