[Inkscape-user] Keep line width when scaling

I am using Inkscape from the command line to batch process a large number of svg's to png's. Some of the svg's need to be scaled before they are converted to png's. The commands for scaling are as follows.

-w, --export-width=WIDTH -h, --export-height=HEIGHT

The problem I am running into is that I do not want the stoke-width to change (scale) when I perform the scaling operation. Is there anyway to accomplish this from the command line? Or can someone recommend another library that can help me out.

Regards,

Joshua
