>I understand better. >"What is visible" is really a flattenned stack of the visible layers >(with an eye in the Layer dialog). Not exactly flattened but merged Flatten will a remove the alpha channel, replacing any transparent area with the background color >The question is the interest of this command. >Alexia, please, could you detail your example? well i can not reply for Alexia but i may give a example. On a hypothetic image add a duplicate layer on top in Overlay mode give me excellent result to enhance details and contrast on some area But terrible result on others On the other hand a similar process but in Multiply mode will do the opposite ,improving that part (i.e under-saturated and too pale sky and clouds)that overlay mode will screw up ,but worsening the rest, with NEW from visible i may save, and then merge the best of both combination easily apply new from visible for combination-1,(overlay) toggle off visibility of that new layer, repeat the process to save result of combination-2(multiply) then i may erase with more on less opacity what i do not like on the New merged top layer and when happy of the combination , save you will not able to get the same using "merge visible layers" once merged will become impossible to recombine the layers in a different mode, You may not need that feature But if you would need it , without NEW from visible,you would need to get trough 5 no too much intuitive steps instead then a single click _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
