...is a simple command-line program (written in Java) designed to convert image files to NFP (the "standard" ComputerCraft image format). Despite it's name, it should be capable of converting from any image format natively supported by Java - even... JPEG... *shudder*.

v0.1b2: Dropbox
v0.1b1: Dropbox

Seeing as this is a command-line program, I'm going to assume you know how to unzip files and stuff.

Usage (v0.1b2 and up)
For detailed usage instructions, run
java -jar PNGNFP.jar --help

For reference, to perform a pixel-for-pixel conversion, run
java -jar PNGNFP.jar nf Tux.nfp Tux.png
If you don't want a ridiculously large image, run
java -jar PNGNFP.jar snf 12 18 Tux.nfp Tux.png
If you want to test drive the new CIE94 colour matching algorithm (still in "beta"), run
java -jar PNGNFP.jar sdnf 12 18 Tux.nfp Tux.png
All of the above commands will convert Tux.png to Tux.nfp.

Just released v0.1b2.
Removes the unnecessary "c" option and adds a new "d" option to use the new (still in testing and kinda glitchy for some reason I can't figure out) Delta E (CIE94) colour matching algorithm (for more "accurate" colour matching).

It would be nice to have a small gui launcher for this tool... running jars in command line is messy!

If you don't like the "messyness" of running the jar, you can use this. http://db.tt/XnY4Y6Je
It's a batch file I made which I put into the "computer" folder of my save. To use it, just drag the image to convertImage.bat.

BTW If you don't put it in "computer," then don't use the computer ID part, leave it blank.

You might want to add export to CCPNG.
