Hi,

Can anyone please recommend a package for generating images from a
bitmap vector. e.g. If I have an list of integers, each representing a
colour on the bitmap, and I want to build a GIF from it (along with some
other meta-info like dimensions).

The main options seem to be RMagick and RCairo, but neither seems to
take a bitmap input. I'd have to create a blank canvas and draw each
pixel. Do-able but inefficient.

Thanks,
Michael
