Run 'make' to compile and then run 'imagejs option jsfile.js' The outcoming image file will be named like the input file + the image ending.. Options are currently bmp, gif, webp, pnm and pgf.
If you add -l as flag you your image is written to the file so that you can open it and view your code as a line of pixels.
This is currently only supported for bmp files.
$ ./imagejs bmp code.js -l
will return a file named code.js.bmp that is viewable.
Code can now be embedded into existing gif files by using the flag
-i with a gif file as argument.
$ ./imagejs gif code.js -i giffile.gif
