NotMyFault Posted June 2, 2023 Posted June 2, 2023 Hi, in case you want to scale a pixel layer containing pixel art, you often run into the issue of unwanted and unexpected blurriness, even if you scale by integer factors. contrast may get reduced (black becomes25% grey, white becomes 75%grey) Edge pixels become partially transparent As example, I try to scale a 32x32px layer to a 64x32px layer (x-axis factor 2, y-axis factor 1) 1. a 32x32px checkered board used as source 2. stretched to 64x32px: gets blurry, reduced contrast, including transparent edge pixels 3. You scale to double target size instead: 128x64, and rasterise 4. Then reduce again by factor 2 to target size 64x32px, and rasterise again: no blurriness This is intended as workaround until Affinity might provide a better out-of-the-box way to rescale pixel art, amoraleite 1 Quote Mac mini M1 A2348 | Windows 10 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps. My posts focus on technical aspects and leave out most of social grease like „maybe“, „in my opinion“, „I might be wrong“ etc. just add copy/paste all these softeners from this signature to make reading more comfortable for you. Otherwise I’m a fine person which respects you and everyone and wants to be respected.
