usually the stuff displayed on the screen, minus any widgets. The

file exists, it will be replaced.

white
- use white background (default is current display setting)
     
xNNN
- horizontal size in NNN pixels
     
yNNN
- vertical size in NNN pixels
     
-t NN
- color number NN is transparent
     
-b bgImage
- Image file bgImage
is included in the background of the output.
     
-f fgImage
- Image file fgImage
is included in the foreground of the output.
One or more options
may be given in any order. bgImage
and fgImage
must be PNG format.
printim

printim

The following command produces a 1000x800 PNG image into file out.png:
printim out.png x1000 y800
This command produces a 800x600 GIF image, with a white background, into file gifimage.out:
printim gifimage.out gif x800 y600 white
This command produces a GIF image with transparent color 0 and a background image mybkg.png. This means that in image.gif, the background image mybkg.png will be seen wherever the color 0 (background) appeared in the current display.
printim image.gif -b mybkg.png -t 0
