I have a SVG image here which is generated with 'empty space', i.e. only in the top-left corner is image content, whereas the rest is blank. I think it should be trivially possible to have an automated way to crop the image size to the bounding box of the objects - at least for some svg tooling like rsvg. However I am unable to find the 'command line trick' for this, etc.
I would like to do this on the command line (i.e. as part of a build script)
In principle I would be interested in a solution to the same problem but for pixel-based formats such as PNG as well.
