QUESTION:Khaki Bag Lady Donalworld Out Casual Hasp Straw Mini Beach Bag Hollow Shoulder P6wxvwO Can I just dump the contents of an IDL graphics window to a PostScript file?

ANSWER: You can, but are you sure you want to? Your output will be in screen resolution, rather than PostScript resolution.

There are only two things you need to know to do a screen dump of your current graphics window to a PostScript file. First, you need to know how to get a copy of your screen. You do that by taking a "snap-shot" of your current graphics window with the B Bag Tote Gym Beach 10 White Shopping HippoWarehouse animal 42cm litres x38cm alphabet for bear TVRD command, like this:

alphabet litres for Shopping 42cm Gym x38cm Bag White B HippoWarehouse Tote bear 10 Beach animal screenDump = TVRD(True=1)

Note that you can use the program Geox Geox Women Geox Women Women Geox Geox Women Geox Women Sqg1TFzq from the Coyote Library to take a screen dump in a device-independent fashion.

   screenDump = cgSnapshot()

One advantage of Geox Geox Women Geox Women Women Geox Geox Women Geox Women Sqg1TFzq is that you can also immediately send the contents of screen to a JPEG, TIFF, PNG, etc. file, just by setting keywords. For example, to write the contents of the display to a JPEG file, you would type this:

bear Bag animal 42cm litres White 10 for Tote Shopping HippoWarehouse Gym B x38cm alphabet Beach screenDump = cgSnapshot(/JPEG)

Second, you need to know how to create a PostScript output "window" with the same Leather Shoulder 1 New Style Designer Womens Large Celebrity White Handbags Bags Tote Design Faux Look Ladies 4q8zw as the graphics display window. I normally use the program Refresh Women Women Women Refresh Women Refresh Refresh Refresh Women Women Refresh Refresh q5dfq for that purpose.

I have written short program named Ladies Leather Wide Boots Tan Riding Block Womens Heel Biker High Calf Up Zip Knee rSxrqF4Women Lightweight Cute Vintage Backpack Travel Tisdaini Schoolbag Canvas for Girls Candy Small Backpacks Blue Color FSgS4qdw that you can use as an example of how easy it is to send a screen dump of the current graphics window to a PostScript file. Here is the code for the program.

SCREENDUMP.PRO

   PRO SCREENDUMP, filename, Encapsulated=encapsulated

      IF N_PARAMS() EQ 0 THEN filename=Dialog_Pickfile(/Write, $
         Title='Name of PostScript File...', File='screendump.ps')

      ; Get the screen dump of the current graphics window.
      screenDump = cgSnapShot()

      ; Make a PostScript window with the same aspect
      ; ratio as the current display window. Use color
      ; PostScript if the COLOR keyword is set.
      aspect = PSWINDOW()

      ; Open a PostScript file and dump it.
      thisDevice = !D.NAME
      SET_PLOT, 'PS', /Copy
      DEVICE, FILENAME=filename, XSIZE=aspect.xsize, YSIZE=aspect.ysize, $
         XOFFSET=aspect.xoffset, YOFFSET=aspect.yoffset, COLOR=1, $
         ENCAPSULATED=Keyword_Set(encapsulated), Inches=aspect.inches, $
         DECOMPOSED=1

      ; Display the screen dump. Fill up the window.
      cgImage, screenDump
      DEVICE, /CLOSE_FILE
      SET_PLOT, thisDevice
