 The manpage says:
    Image formats may support sub-options, which are specified using
   additional words in the value to the -format option.
 This sounds to me as if you need to specify the additional options like
-scaletowidth *with* the -format option, like so:
    -format [list svg -scaletowidth 24]
 instead of
    -format svg -scaletowidth 24
 R'

Mark,
sorry for the odd format. It is always bad, if internals expose on user level. This is an internal issue. There is only the "-format" string which is communicated to the image format driver. Instead of adding something like "driver options", this format string was extended to a list.
I would love to change this one day...
Thank you for your understanding,
Harald
