   Hi, is there a library for Emacs that would allow me to use
   elisp to generate an image file? E.g. a function that takes
   an array of RBGA color values and outputs a PNG file?

I (wrote and) use xpm.el (et al):

 http://www.gnuvola.org/software/xpm/

You can generate XPM and convert to PNG (or any other format).
In the source repo, see flower.el for an example program (that
shows the Code Enhancement Opportunity that lies ahead.  :-D).
