You were almost there :-). paintlib includes a bitmap viewer as a sample program. Use it as base for your own implementation.
Oh, and in response to Francois: paintlib won't read complete postscript files, but if you only need the tif previews embedded in some (most?) postscript files, paintlib will decode them for you.
