Folks,
I've run into an interesting little problem. I have reason to want to
know if the current PostScript device configuration is set up to make
encapsulated PostScript output or not.
I wrote a function that takes the output of the Help, /Device command
and parses the information contained in that output to discover the
"mode" of encapsulation. Here is the relevant line of output:
Mode: Portrait, Non-Encapsulated, EPSI Preview Disabled, Color Enabled
The problem is, in IDL 8.3.2 on Windows the encapsulation mode never
changes!
IDL> Set_Plot, 'PS'
IDL> Device, /Encapsulated
IDL> Help, /Device
Available Graphics Devices: CGM HP METAFILE NULL PCL PRINTER PS WIN Z
Current graphics device: PS
File: C:\IDL\tester.eps
Mode: Portrait, Non-Encapsulated, EPSI Preview Disabled, Color Enabled
I've confirmed the PostScript device *creates* an encapsulated
PostScript file when I configure the device like this. It just never
tells me it is doing so.
Is this the case in other versions of IDL, too?
Cheers,
David

Hi David,
you should check the device after opening the file (= after the first plot command):
IDL> set_plot, 'ps'
IDL> device, /encapsulated
IDL> help, /device
File: <none>
Mode: Portrait, Non-Encapsulated, EPSI Preview Disabled, Color Disabled
IDL> plot, dist(5)
IDL> help, /device
File: idl.ps
Mode: Portrait, Encapsulated, EPSI Preview Disabled, Color Disabled
regards,
Lajos

Yeah, too late by then. :-(
Cheers,
