    Help! How do I get this thingy to work properly? I ask it for a pixel and grab the return in a long, but it returns all these fruity values like -1 and -531 and things like 20 (which is absolutely not one of the pixels in my pic), and so on. How do I get it to work in 16-bit and 32-bit color modes? PLEASE HELP AHH!

    depends, what mode are you using, negative values might occur if you use 32 bit color mode. if you use palettes you get the palette index
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
