- Reads a portable anymap as input. Scales it by the
- specified factor or factors and produces a portable anymap
- as output. If the input file is in color, the output will
- be too, otherwise it will be grayscale. 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.
-
- You can specify different sizes or scales for each axis.
-
- Or, you can use the special ----xxxxyyyyssssiiiizzzzeeee flag, which fits the
- image into the specified size without changing the aspect
- ratio.
-
- All flags can be abbreviated to their shortest unique
- prefix.
-
- If you enlarge by a factor of 3 or more, you should probably
- add a _p_n_m_s_m_o_o_t_h step; otherwise, you can see the original
- pixels in the resulting image.
