GraXXoR Posted November 9, 2024 Posted November 9, 2024 Hello people, forgive me for posting a question without first contributing anything myself but I have been banging my head searching Google for a few days (not continuously, obviously...) and am unable to find a suitably quick solution. I have an image that I need to cut out a dozen squares of the same size from random locations within the image. In Photoshop, I can just do this: M sets Marquee tool One click with the mouse places the presized marquee int he correct location. Ctrl-X cuts out the square. Ctrl-V pased the square as a new image. Move the cut out to the correct place with mouse. -- Repeat 12 times and the image is complete: Total time about a minute and a half. In GIMP, the flow is the same except that after Ctrl-V, I have to click the "create new layer from selection" icon in the layers panel. In Affinity Photo 2, I cannot find a way to fix the size of the marquee for cutting out a shape... Of course, I can drag the cut tool to the correct size each time or type in the size each time in the transform panel, but this makes the task significantly slower by a factor of about 3. Am I stuck in a photoshop way of thinking, is there an Affinity workflow that can be just as clean and fast? Thank you so much for any help you can provide. I'm certain I'm missing something fundamental. Quote

I am not familiar with how this works in Photoshop but how does it set the size of the marquee before you click & drag it out to some desired size, & how does it determine what the correct location is?

GarryP Posted November 9, 2024 Posted November 9, 2024 You can create a precisely-sized pixel selection in the first place by creating a Rectangle (or other shape) and making the pixel selection from that (use a black-filled shape with no Stroke for a good clean selection). In Photo only, you can save a pixel selection to a Spare Channel and then use it again whenever you need to, moving it (if necessary) via the Quick Mask functionality. See attached video for a quick example of both. (It might be possible to omit some of the steps in the video to make the process quicker, I just did it the way I did it so that the process was clear.) 2024-11-09 09-11-10.mp4 GraXXoR 1 Quote

Using layers and converting to outlines removing the layer then being left with the outline then creating a marquee from the outline then use the marquee to cut the shape out. I fear that this will take significantly longer than 90 seconds to cut out a dozen shapes. 8 hours ago, R C-R said: I am not familiar with how this works in Photoshop but how does it set the size of the marquee before you click & drag it out to some desired size, & how does it determine what the correct location is? R C-R Thank you for the reply. In Photoshop: Set up: Press M for marquee Set the marquee tool to exact pixel mode type 200 x 200 (or whatever) in the parameter box Here's the loop click on where you want to cut (the marquee will appear centred around the mouse). Ctrl-X to cut the shape. Move mouse to desired location. Ctrl-V to dump cut square to new layer. Press A and drag the cut layer to the correct place by mouse. Press M to cut a new hole. repeat In GIMP it's the same but press R to select the rectangle and M to move the cut layer. Total time 8~10 seconds per cut.
