cgblendimage without a window? - a bit stuck! [message #83758]

Hi there,

I have 2 snapshots which I'm blending using cgblendimage. It works fine with this:

window,xsize=580,ysize=590
cgBlendImage, snapshot2, snapshot, ALPHA=0.3
void = cgSnapshot(FILENAME='test.png',/nodialog)

BUT .... I don't want to instantiate any 'window' - I want this all to be an offline batch process.

This works (or seems to):

set_plot,'Z'
cgBlendImage, snapshot2, snapshot, ALPHA=0.3
void = cgSnapshot(FILENAME='test.png',/nodialog)

EXCEPT that the final image has been rescaled to 640 * 480.

So, how do I get this to work without a window - but with the correct xsize and ysize values ?

Cheers

George.
