Hello,

I am using Coyote library in IDL. Is there a direct way to save the figure file in .PNG format instead of saving first in .PS format and then converting to a .PNG format?

cgPS_Open, FigFile

...
...
...

cgPS_Close
cgPS2Raster, FigFile, /PNG

Thanking you in advance,
Regards,
Madhavan

cgPlot, data, Output='myfile.png'

You can find the on-line help for these routines here:

There are options that can control what happens to the PS file, if that's your concern.

The question is _why_ you don't want the PS file first.

While we're here, this is a little more succinct:

cgPS_Open, FigFile
...
...
cgPS_Close, /PNG

which calls cgPS2Raster under the hood.

Thank you David & Philip. The reason why I don't require PS file first is that it is occupying more space and the file size is big sometimes.

Thanking you once again,
Regards,
Madhavan
