Hi folks,
I enjoy working with objects graphics when I can... Today I'm trying
to export an IDLgrScene to PS using the IDLgrClipboard. I've a problem
with one image that I added to some models using the ALIAS keyword.
When I call the Draw method of the clipboard I've the error you can
find at the end of this message.
If I delete the image, all works good !
Testing my code I realized that the problem is the size of the image
[3,2304,2048]. I don't visualize all the image because the viewplane
is smaller so, actually, the visualized part is something like [*,
0:300,0:300]. I can't cut the image because I implemented a camera and
the user can move the viewplane (PAN the camera) in order to see other
parts of the image. Also, the user can zoom in/out and visualize more
area.
The only problem is when I try to export to PS. Any suggestions to
solve this ?
thanks
nata
