- DESCRIPTION
- Reads a portable pixmap as input. Scales it by the speci-
- fied factor or factors and produces a portable pixmap as
- output. You can both enlarge (scale factor > 1) and reduce
- (scale factor < 1). You can specify one dimension as a
- pixel size, and the other dimension will be scaled
- correspondingly. You can specify one dimension as a scale,
- and the other dimension will not be scaled. Or, you can
- specify different scales for each axis, either as scale fac-
- tors or as pixel sizes.
-
- All flags can be abbreviated to their shortest unique pre-
- fix.
