Is there a way to center the whole drawing to the page in Inkscape with just a Terminal command? I need to do this for a couple hundred images. Manually, you do this by hitting "CTRL+A", "CTRL+ALT+H", "CTRL+ALT+T".

Halfway through writing this question, I figured it out. I'll post the answer.

With "foo.svg" as the image to edit:

inkscape --verb=EditSelectAll --verb=AlignHorizontalCenter --verb=AlignVerticalCenter --verb=FileSave --verb=FileQuit foo.svg


To edit all svg images in the current directory:

inkscape --verb=EditSelectAll --verb=AlignHorizontalCenter --verb=AlignVerticalCenter --verb=FileSave --verb=FileClose *.svg


But this second command opens a ton of windows, which will make your computer crash if you're editing too many images. For Linux only, this command will work better:

for img in *.svg; do inkscape --verb=EditSelectAll --verb=AlignHorizontalCenter --verb=AlignVerticalCenter --verb=FileSave --verb=FileQuit $img ; done


For the above command, if any of the files are symlinks, Inkscape will edit the target file that the symlink points to. If you don't want Inkscape to do this, you can filter out any symlinks with this command:

for img in *.svg; do if [[ $(readlink $img) == "" ]] ; then inkscape --verb=EditSelectAll --verb=AlignHorizontalCenter --verb=AlignVerticalCenter --verb=FileSave --verb=FileQuit $img ; fi ; done



While I'm at it, I might as well post the bash script I made for this:

#!/bin/bash
# inkscape-center <file-or-directory>...

_analyse() {
if [ -d "" ] ; then
_centerAll "" ;
else
_center "" ;
fi
}

_centerAll() {
cd "" ;
for img in *.svg; do
_filterSyms "${img}" ;
done
}

_filterSyms() {
if [[ $(readlink "") == "" ]] ; then
_center ""
fi
}

_center() {
inkscape --verb=EditSelectAll --verb=AlignHorizontalCenter --verb=AlignVerticalCenter --verb=FileSave --verb=FileQuit ""
}

for arg ; do
_analyse "${arg}" ;
done


I called it inkscape-center and run it like this:

inkscape-center <file-or-directory>


It takes as many arguments as you want, so you can do something like this:

inkscape-center 1st.svg 2nd.svg 3rd.svg 4th.svg


Be careful- If you specify a directory instead of a file, it'll edit every svg file in that directory.
