Printing large images from cmgui
There is information in the FAQ about printing large images in cmgui. http://cmiss.bioeng.auckland.ac.nz/development/help/cmgui/faq.html
However there seems to be a little problem with some of the tiles getting the incorrect amount of transparency sometimes on NVIDIA graphics. So far it always seems to work if the printed area in both directions is multiples of 1024 (the tile size). There is a collector bug on this issue http:/hello/CMISSFolder/CMISSfeatures/91/base_view
