[Gimp-developer] Dithering

2004-01-07 Thread David Gmez
Hi all, Just installed gimp-2.0pre1 ;) I've scanned some jpeg images with a 24bit depth. Some of them are old photographies in blackwhite that show 'bands' when are displayed on a 16 bit depth display. After digging in the menus i noticed that the image could be transformed to a indexed pallete,

Hi David ;), This is a normal phenomenon when moving to higher bitdepths. Unless you're talking about 16 bits in total, and not 16 bits per channel, in which case I'd be a bit mystified... Yes, i meant 16 bits per channel ;) Floyd-Steinberg dithering is basically a way to approximate more

Hi Yosh ;), The GIMP display canvas uses the dithering routines from GdkRGB which is probably what you are refering to. Of course this does only affect the display, not the image data. I am not sure but I think I remember a plug-in that could apply dithering to RGB images w/o converting
