allenbham Posted November 19, 2019 Share Posted November 19, 2019 Is there any way to figure out how many pixels of a certain color exist in a jpg file? Or alternatively, what percentage of a file's pixels are a certain color? I'm trying to figure out the total surface area of a group of oddly curved, organic shapes.

firstdefence Posted November 19, 2019 Share Posted November 19, 2019 I doubt that's possible in any of the Affinity apps. There are image analysis/forensic apps that would be better suited to your question, namely ImageJ: https://imagej.nih.gov/ij/ this is another release of ImageJ: https://fiji.sc allenbham 1 Quote iMac 27" 2019 Somona 14.3.1, iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

allenbham Posted November 19, 2019 Author Share Posted November 19, 2019 v_kyr, thank you --- this was just what I was looking for and I had no idea it existed as its own separate service. It's easy and directly suited for what I'm doing here. Quote Link to comment Share on other sites More sharing options...
