I tried to 'montage' 15000 small PNG images (about 10kb each) in order to make them all into one big image, but midway through the process I get a warning that I have no disk space left. I have 30gb left in my SSD.
The command I'm running:
montage -mode concatenate -background none -tile "101x" "${X}_*.png" out.png
Why does this happen and how much disk space would I need for such a task?
