API Design about samp-bitmapper

[Hual]

I suggest having the open function end with varargs for the colours whose data (position) you want to extract, like open(filename [[[, colour1], colour2], ...]) to make caching more efficient.

Yes that would make sense, and no args would result in all colours being cached I guess.

I say that because I have an image that literally only has 4 colours in it, white and 3 shades of green for 3 different types of trees. I know the colours already so I wouldn't need to specify them again.

This could also be used to assert if the colours actually exist in the image. If I specify Red Green and Blue but there are no Blue pixels, the open function could return some nonzero code.
