I was wondering how I can get my 110+ .png map tiles conveniently into a 1:1 pixel ratio size map .png. Ive been scrolling through google and such, and the forum's for the free ware game that I am modding, but the app im 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.

I'd probably roll my own, as that doesn't sound too complicated, and I could add any features I wanted. stb_image, for instance, is a free library that supports both loading and saving of pngs easily. – Jari Komppa Dec 19 '11 at 10:39

Such as this (free license for bloggers and framework developers) or this (completely free but a bit less flexible)?

D:< I spend 2 whole days looking for something and you just whip it out minutes after I ask? Don't get me wrong I am very grateful, but wow! – Tyler Dec 19 '11 at 4:48
The second will be more useful since I can edit the length and width with text. Thanks, you saved me time, sleep and headaches ;). – Tyler Dec 19 '11 at 5:04
No problem, glad it helped :) Finding stuff online is usually easy as long as you know what to search for. In this case I knew immediately that I needed some sort of texture packer or spritesheet maker so... – David Gouveia Dec 19 '11 at 6:05

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

As pointed out by bummzack, montage will work also good.

montage tile*.png -geometry +0+0 wholeImage.png

You could also use ImageMagicks montage command. As described here. – bummzack Dec 19 '11 at 9:37
@bummzack: Thanks, I'm not sure how I missed that. As an informational note only, that site has a very poor rating, I'm not sure why. – Bobby Dec 19 '11 at 9:41
never heard of that WOT reputation thing. The procedure outlined in the blog post works fine though. I have used it myself in multiple occasions. – bummzack Dec 19 '11 at 9:43
+1 for using montage. I've used that many times to make sprites from individual frames. Very handy. – stephelton Dec 19 '11 at 15:43
