Description

Currently, all these command line tools check for the following options as being mutually exclusive (although it is not apparent for the user since it this fact is not documented anywhere):

  +Sxf  --scale-x-factor  [f]actor: float
          scale x axis by factor, auto-compute y axis

  +Syf  --scale-y-factor  [f]actor: float
          scale y axis by factor, auto-compute x axis

  +Sxv  --scale-x-size  [n]umber: integer
          scale x axis to n pixels, auto-compute y axis

  +Syv  --scale-y-size  [n]umber: integer
          scale y axis to n pixels, auto-compute x axis

However, in case the aspect ratio is ignored (option -a), it should be possible to specify a scaling factor or a particular size in pixels independently for both axes, e.g. use "+Sxv 128 +Syv 128" to scale the input image to a fixed size.
It should also be checked whether combinations like "+Sxv 128" (pixels) and "+Syf 0.5" (scaling factor) are possible...
