In Inkscape, resize both the document and its content at the same time

by

I’ve been struggling to do something that would seem pretty basic:

In Inkscape, how can I resize the document and its content (i.e. drawings) at the same time?

A little bit of context: I want to resize a fairly large number of SVG documents from The Noun Project (they are typically 100x100px docs) without having to explicitly resize the actual drawings.

N.B: If there’s a command line solution, I can work with that too!

Answer

You haven’t mentioned what OS you’re running. I’m using Ubuntu, and I’ve been able to use librsvg2 successfully.

If you have access to Ubuntu, here’s what you can do. First, install librsvg2:

sudo apt-get install librsvg2-bin

Then, cd to the directory that has your SVGs (make sure it only has SVGs!) and use a command like the following:

for old in *; do
    new="$(echo "$old" | sed -e 's/svg$/new.svg/')"
    rsvg-convert "$old" -w 160 -h 160 -f svg -o "$new"
done

This will create a new batch of SVGs with dimensions 200px by 200px, and saved as “original-file-name.new.svg”

Calculating dimensions is somewhat confusing. For converting SVG to SVG, you need to do a little bit of math. The “height” and “width” options in rsvg-convert use pt, not px, in such cases, so use 80 if you want 100px, 120 if you want 150px, and so on.

You can also use rsvg-convert to output PNGs. It is much better at rasterizing the file than ImageMagick, at least in my experience. Notice that you need to change -f to png, you need to change the output save pattern from 's/svg$/new.svg/' to 's/svg$/png/', and you enter the width and height that you want as the pixel values.

for old in *; do
    new="$(echo "$old" | sed -e 's/svg$/png/')"
    rsvg-convert "$old" -w 200 -h 200 -f png -o "$new"
done
