Preview logos by compositing onto the mockup at scale

To judge a merch logo at real scale, composite the trimmed transparent PNG onto the mockup screenshot with ImageMagick: magick base.png \( logo.png -resize 66x \) -geometry +X+Y -composite out.png, then save a zoomed crop. If the mockup has placeholder text such as "YOUR LOGO", remove it first by cloning nearby fabric: magick in.png \( +clone -crop WxH+X+Y +repage \) -geometry +X2+Y2 -composite clean.png. Choose the source region carefully and check the patch in a crop, because lighting varies across the fabric. In this case, a patch from below the text was visible, while one from directly above blended seamlessly.
