HuwR Posted January 29 Posted January 29 I wonder could anyone enlighten this novice on how to stop layers and cut/paste blurring. Any help will need to assume I have no real understanding of the technicalities. I am an illustrator and use Photo to create art work. Thanks Huw Screen Recording 2025-01-29 at 13.06.40.mov Quote
GarryP Posted January 29 Posted January 29 (edited) Select the Move Tool, then select a Pixel Layer (one of the layers you pointed out in your video), then look at the Transform Panel. If the values there are not measured in Pixels then you need to change the Document Unit of Measure to Pixels (one way is via menu "Document -> Document Resize"). Then go to Settings / User Interface (via the Edit menu) and make sure that the Decimal Places for Unit Types for Pixels is greater than 2 (see attached image). Once that’s done, with the same layer selected as before, look at the X, Y, W and H values again in the Transform Panel. If any of them are not integers (whole numbers) then that is probably where the problem lies. If this is so then tell us and someone can explain the next part. Once you have been through all of the above, if you give us a full-screen screenshot where you have the Move Tool selected, and one of your layers selected, with the Transform Panel visible, then that would be useful.

HuwR Posted January 30 Author Posted January 30 Hello and thank so much for your patience with my requirement for very step by step basic and fully described explanations. What you wrote made sense and I hope I have understood the process. I have attached 3 screen shots which I hope describe where I am. They appear as full screen this end. Huw Quote
GarryP Posted January 31 Posted January 31 Thanks for the screenshots. In your third screenshot you can see that the X/Y/W/H pixel values in the Transform Panel (bottom right) are not integers. This means that at least one of the selected layers is not aligned to the document’s pixel grid, I suspect that it’s the one with the ‘white fill’ (the man). Because of this, when you attempt to merge or rasterise that layer, or a combination of layers containing that layer, the software will have to ‘smush’ the pixels from the non-aligned layer ‘into’ the pixels of the document. Imagine trying to use a square piece of greaseproof paper to make a lining for a round cake tin; there will be parts of the paper which don’t fit nicely into the shape of the tin so you need to ‘crease’ the paper to get it to fit. The same sort of thing happens with the pixels here as the software needs to come up with a compromise where the pixels of the non-aligned layer don’t quite ‘fit’ the pixels of the document – parts of some pixels don’t align with other pixels. Because there’s no such thing as a part of a pixel – a pixel is an ‘atomic’ thing – the software has to guess as to what colour to make each pixel and the result isn’t always as clean as we might expect/hope because the software doesn’t ‘know’ what we expect because it doesn’t ‘know’ what the pixels represent, they’re just numbers. The only way to get round this (under most circumstances) is to make sure that your pixel layers have integer numbers for all of the X/Y/W/H values, and that’s usually done by changing the X/Y values to integers manually (or moving the layer while snapping to the pixel grid) and then resizing the layer, if necessary, but resizing might also cause the same problem. Basically, when working with pixels, make sure you have integer X/Y/W/H values (i.e. have alignment with the pixel grid) and things should be easier. Alfred 1 Quote
HuwR Posted February 1 Author Posted February 1 Hello Gary Thanks for the explanation. As I confessed my understanding is very basic so sorry if I'm asking stupid questions here. I have screen recorded my next set of questions. Any help appreciated. Huw Screen Recording 2025-02-01 at 10.27.08.mov Quote
carl123 Posted February 1 Posted February 1 @HuwR Can you upload that document to the forum so we can see what's going on? Please upload before you do the merging of the layers Quote To save time I am currently using an automated AI to reply to some posts on this forum.

HuwR Posted February 1 Author Posted February 1 Hi - Hope this helps. The layers I'm referencing are towards the top of the layer stack. Many thanks. WINSTON PAGE 16.afphoto Quote
carl123 Posted February 1 Posted February 1 Try this... Select both layers, then... Layer > Rasterise & Trim Layer > Merge Selected Is that better?

HuwR Posted February 1 Author Posted February 1 Whoah! Yes indeed it is!!! No worsening in the existing blur and the un-blurred layer remains un blurred. Many thanks Huw Quote
carl123 Posted February 2 Posted February 2 Great, and just to mention... In the file you sent me you had already corrected the non-integer values as mentioned by GarryP The Rasterise command does this automatically so you could have possibly skipped this step in this example but it's always best to try to work with only Integer values when merging layers. The snapping setting "Force Pixel Alignment" can help with this so best to switch it on as I can see it is not set in your screenshots Quote To save time I am currently using an automated AI to reply to some posts on this forum.
