Notty.RenderDump images to string buffers.
to_buffer buf cap (x, y) (w, h) i writes the string representation of i to buf, as interpreted by cap.
It renders the w * h rectangle of i, offset by (x, y) from the top left.
val pp : Cap.t -> Format.formatter -> image -> unitpp cap ppf i renders i to the pretty-printer ppf.
Note pp is generally meant for development and debugging. It tries to be reasonable, but dedicated IO modules handle the actual output better.
