I was interested in using ICE simply as a tileset generator (without the stitching) and could not figure out how to do it. For example, if one wanted to generate a tile set from a single large image such as a 110MB 13k by 9k pixel jpg from eso.org (eso1208a.jpg).
ICE will not load the file because it expects more than one to stitch. I tried finding a sufficiently close second image to fake it into stitching the two so I could then crop the second, but that wasn't going anywhere ... thoughts?
