I was wondering how I can get my 110+ .png map tiles conveniently into a 1:1 pixel ratio size map .png. I've been scrolling through Google and forums for the free ware game that I am modding, but the app I'm using recognizes only .png files, and I want more than 1% of the map. If you guys know of a program I would be very appreciative.
ImageMagick with it's convert -append can also be used for this. Though, it only does appending into one direction, but if your tiles are named ascending (f.e. tile001.png) it can still be used in a loop:
convert tile00*.png +append line1.png convert tile01*.png +append line2.png convert line*.png -append wholeImage.png
montage tile*.png -geometry +0+0 wholeImage.png
