I want to visualize what an image(768x1024) looks like when it's scaled down and tiled. I use
Gimp, so I select, ctrl-scale to something small (whateverx180), select, copy, edit/paste as../new pattern (give a name, save), then I open a blank white canvas, and fill with the pattern:
Is it the expected behavior of the tool that I see those seams (the background color filters through) on the edge of the individual pattern?1
1. It doesn't happen with the default patterns supplied. And I can fill the canvas with blue first to avoid it. The affected area parameters don't change the result. I made a comparison using Imagemagick's montage, and it tiles without those seams. I am a beginner.
