(gimp-selection-float drawable offx offy) i think if you use x1 and y1 from (gimp-selection-bounds image) it will work. then make a new layer of that. > 7) clear the selection (in translation layer) > (gimp_context_set_background (gimp_image_pick_color img clickX clickY)) > (gimp_drawable_fill (gimp_selection_save img) GIMP_BACKGROUND_FILL) if you make sure the layer transparency is toggled (gimp-layer-set-lock-alpha layer lock-alpha) you should be able to fill the original pixel region without a lot of extra steps. to do this, float your selection first and make that into a new layer. then invert the selection and fill that. then toggle the transparency and fill the whole layer. > 8) open a box to edit text and then render it to the new selection in tlayer > (gimp_textget_extens_fontname)/(gimp_text_fontname) ?? > How do I get the dimensions of the "useful" area? > How do I get the text inteh first place?

Sounds like you're trying to erase the contents of a speech bubble and fill it with new text. The magic wand will select the white inside the bubble (assuming it is actually closed, which isn't guaranteed in comics, so you may get some bleeding which would ruin the entire thing) but you'll have to delete the text by doing some sort of combo-selection which will be kinda finicky. > 3) Clear the region to a specified colour. > 4) Edit a (possibly long) string and fit it into the cleared region > (eventually scaling the font to make it fit). > > Nice to have: > - save the "original" region contents in a layer before killing it. > - render the string to a different layer than the background (this would > enable to see either the "old" or the "new" content simply marking the two > layers visible/not-visible. 2.x text tools put text in a seperate layer... > I need this in order to translate some comics I scanned. Maybe you want to make a background later, select the area(s) with the magic tool (click magic tool, shift click-click-click as necessary), cut, paste in a new layer, hide the cutout's layer and then create a text layer with your text. I'm not sure if I'm being clear though, so it might not be helpful enough. -- ~Mike - Just my two cents - No man is an island, and no man is unable. ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

Select by color would be better to use in automation. it will find more than one region though, if more than one exists on the image. i wrote a script that used fuzzy selection on a directory of images. i knew that i could pick from this one location and it would always work, though. carol ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
