saving bitmaps from graph control

buzzard — Fri, 28 Apr 2000 19:07:03 GMT

I have a graph which plots data in a LabWindows/CVI program. I would like
to be able
to save a "snapshot" of the graph to my harddrive at any given time. I have
setup
a callback which does the "GetCtrlDisplayBitmap" function and takes the snapshot,
but I don't know how to then save this particular
snapshot as an image file for future reference. Any advice?
Thanks in advance

This FP for CVI 5.5 will save it to a compressed PNG file:
