Thank you for your very quick answer. I have some other questions. First, I couldn't manage to get it work with the standard input. I tried with - with '-' and with "-" like that: cat Dimocarpus_longan_fruits.jpg | gegl -o - -x "<gegl><node operation='gegl:c2g'><params><param name='radius'>384</param><param name='samples'>3</param><param name='iterations'>23</param><param name='rgamma'>1.8</param><param name='strength'>1</param><param name='gamma'>1</param></params></node><node operation='gegl:load'><params><param name='path'>-</param></params></node></gegl>" | display - cat Dimocarpus_longan_fruits.jpg | gegl -o - -x "<gegl><node operation='gegl:c2g'><params><param name='radius'>384</param><param name='samples'>3</param><param name='iterations'>23</param><param name='rgamma'>1.8</param><param name='strength'>1</param><param name='gamma'>1</param></params></node><node operation='gegl:load'><params><param name='path'>'-'</param></params></node></gegl>" | display - cat Dimocarpus_longan_fruits.jpg | gegl -o - -x "<gegl><node operation='gegl:c2g'><params><param name='radius'>384</param><param name='samples'>3</param><param name='iterations'>23</param><param name='rgamma'>1.8</param><param name='strength'>1</param><param name='gamma'>1</param></params></node><node operation='gegl:load'><params><param name='path'>\"-\"</param></params></node></gegl>" | display - Another question: is there a way to blend layers by combining the HSV or HSL values (ie. take hue and saturation from one layer and light from the other one)? ImageMagick calls these modes: Luminize or Colorize; Gimp calls them Color or Value: http://www.imagemagick.org/Usage/compose/#hue http://www.linuxtopia.org/online_books/graphics_tools/gimp_advanced_guide/gimp_guide_node55_004.html Thank you by advance, best regards, -- Thomas Baruchel _______________________________________________ Gegl-developer mailing list Gegl-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer
