Hardness 075 / Size 5.00) - merge path layer layer with the black bird - done [attachment=7707] RE: Creating an "opposite" image - tmanni - 03-30-2022 Another three steps workflow : 1. Colors > Curves... - select channel Alpha - inverse the curve : move the bottom left point to the top left and the top right point to the bottom right 2. use Fuzzy Select with these settings - Mode: add to current selection - Select transparent areas checked - Diagonal neighbors checked - Threshold 255.0 - Select By : Alpha to select the exterior areas of the subject 3.

PixLab, I had problems with the image provided by the OP. Image as seen after fuzzy select a transparent area. In addition to the lack of uniformity in the background transparency, the contour always presented a pixelation not shown in the other results exposed here on the forum. So I changed the image before testing the steps.

Click on the OP's image ➤ a new window/tab opens, right click ➤ copy image, then in GIMP 'File ➤ Create ➤ From clipboard` you got the original from the OP which has no defect or here directly https://www.gimp-forum.net/attachment.php?aid=7673 RE: Creating an "opposite" image - Krikor - 03-30-2022 By superimposing the final result (the opposite image) over the contours of the initial image, with a red layer in the background, it is possible to see a small gap generated in this process. At least in my tests, only the procedure suggested by Denzjos did not present this gap. RE: Creating an "opposite" image - PixLab - 03-30-2022 denzjos and tmanni, always good to see a different thinking/solution, thanks a lot for your input. |
