Hi Ian,

I never got around to finishing setting up gtk-doc for the glib
bindings.  Someday, I'll find the time.  There are doc comments in the C
code, though:

/**
 * poppler_page_render_to_pixbuf:
 * @page: the page to render from
 * @src_x: x coordinate of upper left corner
 * @src_y: y coordinate of upper left corner
 * @src_width: width of rectangle to render
 * @src_height: height of rectangle to render
 * @scale: scale specified as pixels per point
 * @rotation: rotate the document by the specified degree
 * @pixbuf: pixbuf to render into
 *
 * First scale the document to match the specified pixels per point,
 * then render the rectangle given by the upper left corner at
 * (src_x, src_y) and src_width and src_height.
 **/

Thanks,
-Jonathan
