[feature] .. despeckle

[frissenm]

Hi, it would be a good idea (IMHO) to add: - despeckle - remove jpg artefacts - dust removal algorithm in GC Also, the levels dialog could be enhanced (the little arrows under the histogram are very hard to move) and: split channels.. this function would be more useful if it actually split the channels into 3 different images (or layers.. ).. oh, and CMYK would be nice as well..

Maybe something can be found in the 'gimp' sourcecode? I'd help out, but it's been too long I've written a single line of code thanks for considering, Marco PS: I'm a switcher (yep, one of those), and loved the features in photobrush for windows platform (http://www.mediachance.com).. maybe you can take a look for inspiration?

thorsten, check out the usenet group: comp.graphics.algorithms (through google http://groups.google.com/groups?hl=nl&l ... hics.algo= rithms) I've seen requests for the despeckle algo (and others) on there. Grua�, Marco
