}Usage
Step 1
Get a picture (requirement: 24-bit .bmp file. Personally, I DO NOT recommend resolutions larger than 100 * 100, unless you have a really powerful processor) which you want to convert. Copy the source code above and save it in a .cpp file.
Step 2
Put the picture and the cpp file in the same folder. Use Dev-Cpp to compile the code (I did not test the code using other compilers). Run the .exe file. Follow the instructions and you'll get a .xml file in the same directory.
Step 3
Put the .xml file in your craft data folder (generally at C:\Users\Username\AppData\LocalLow\Jundroo\SimpleRockets 2\UserData\CraftDesigns).
