lettergothic Posted June 16, 2019 Share Posted June 16, 2019 Because of black in an image abutting the black background—which I want to delete, I can't use the wand to select the black background. In situations where I can use the wand, however, I select the background, hit delete, black disappears and I've got the desired checkerboard. However, when I select the object w/the magnetic lasso, invert the selection and hit delete to get rid of the b'ground—nothing happens; it doesn't delete the black b'grnd. How come it doesn't delete the b'ground like the wand selection? How do I delete the b'ground with the lasso selection? Thanks again, as always. lettergothic Quote Link to comment Share on other sites More sharing options...
lettergothic Posted June 17, 2019 Author Share Posted June 17, 2019 Errka Petti, thanks for responding. I'm sorry but, unfortunately, I'm afraid that I don't understand your response . . . Could you please explain in more detail. thanks, lettergothic Quote Link to comment Share on other sites More sharing options...
Staff Callum Posted June 17, 2019 Staff Share Posted June 17, 2019 Hi Lettergothic, It should work if you have the layer rasterised and selected. Please could you provide a screen recording of you using the Lasso tool? Thanks Callum Quote Please tag me using @ in your reply so I can be sure to respond ASAP.

lettergothic Posted June 17, 2019 Author Share Posted June 17, 2019 Callum, thanks very much for responding. I appreciate it."...have the layer rasterised" — The image is a photograph on a black ground. It's already a bitmap when I open it in APhoto, no? One rasterizes vector images, no? There's only one layer."...provide a screen recording" — I don't know how to do that but I do know how to use the "wand" and the "lasso". I've attached the image in question—an open book on a black bg. I want to eliminate the bg. so I just have the irregular shape of the book. I've successfully done this on about 6 of them just like this one. I can't (don't know how to) use the wand on this one because of the B+W image (bottom center) abutting the blk. bg. The wand selection enters the image and I can't seem to get the "wand-subtract" setting to eliminate the inadvertent selection of portions of the image. With the magnetic lasso, I can switch to manual mode right before the problem area, trace the edge of the page across the problem area manually (sort of :-/ ) and them resume "magnetic" right after the image. When I close the selection, I get the marching ants around the book spread. I choose "invert selection" to select the blk. bg. I hit "delete" (as I do, successfully, with the wand) and nothing happens—the bg is not deleted. How do I get the bg. to delete? Why is this different that the wand "delete"? Is there a technique with the wand—that I'm unaware of—that I could use to solve this? In the end, of course, I just want a fast, non-manual way of outlining the spread (pretty well) and ditching the bg. I can do it, except in this case, because the wand can't distinguish the blk. in the image from the blk. bg. Thanks very much. I really appreciate your help.
