- The 'background' csh script changes the screen background color/image via pft
-
- Usage background -reset
- background -gray GrayShade
- background -RGB Red Green Blue
- background -{file, center, scale, minscale, tile, debug} FileName
-
- 0.0 <= GrayShade, Red, Green, Blue <= 1.0
- FileName = Encapsulated PostScript file.
-
- Options can be shortened to just their first letter, eg. 'background -g 0.666'
- The 'gray' & 'RGB' options can be combined with 'file', 'center' and 'minscale'
-
- The 'file' option just puts up an image at {0,0}, the 'center' option centers
- the image on the screen instead. The 'scale' and 'minscale' fit the image to
- the screen -- 'scale' maintains aspect ratio, 'minscale' doesn't. The 'tile'
- option tiles the screen with an image. Only one of these options should be
- used at a time.
