Hi. I get exit code 15 when memory is not enough. ImageMagick has -limit param for example

Yes, there is a limit functionality:

Note that by default it's set to 64MB of memory + size of decoded RGBA image. So either image you're working on is larger than your memory, or there's something very broken with your setup if 64MB is too much.
