If your processing pipeline looks like "grabbing -> transformation -> display" then you should look at some tv viewers (like xawtv) or one of the many paytv-decoders, which are designed for realtime performance. -- -==- | ==-- _ | ---==---(_)__ __ __ Marc Lehmann +-- --==---/ / _ \/ // /\ \/ / [EMAIL PROTECTED] |e| -=/_/_//_/\_,_/ /_/\_\ XX11-RIPE --+ The choice of a GNU generation | |

Currently the image processing is contained in something we call the core which isn't a library and can hardly be used without user interface. The only possibility you'd have to use it for your needs is to write some script which utilizes GIMP core. > 1) Is there any documentation on the gimp source above and beyond the > source itself? libgimp is documented in the source tree in the directory devel-docs and there's some misc documentation in docs but since libgimp can't be used for imageprocessing it possible isn't of much interest to you. > 2) Is there any reason to think this should be impossible?

The pixelconversions you mentioned would have to be VERY simple to achieve that speed. Maybe you should try some library like imlib gdk-pixbuf or imlib2 which are able to do simple transformations too and are a lot easier to utilize and faster for such a purpose. -- Servus, Daniel
