Hi, I have written some operations for my own use into gimp. Let me know if you are interested by some of them, I will write tests and push to master. * median-blur (quite fast, histogram based computation of individual RGB channels, using a "zigzag" sliding window) * component-extract (extract a component from RGB, HSV, HSL, CMYK, YCbCr or LAB color spaces, very useful in a mask production workflow) * lab-levels (like the current levels op, but in LAB color space) * shadows-highlights (lighten shadows and darken highlights) * waveform (produce a luminance waveform scope, RGB parade will come soon) * color-clip (clamp pixels values into 0.0 - 1.0 range) Thomas Manni _______________________________________________ gegl-developer-list mailing list List address: gegl-developer-list@xxxxxxxxx List membership: https://mail.gnome.org/mailman/listinfo/gegl-developer-list
