Ubuntu – How to render SVG files with subpixel hinting for text

image-viewersinkscapesvg

I need to render an SVG image with very small text, so I would like to use subpixel hinting, like so:

enter image description here

Inkscape doesn't provide an option to use subpixel hinting for PNG export, neither does the GIMP. However, I get excellent results when I view the image in EOG, the Gnome Image Viewer.

How do I use whatever Image Viewer uses to render my SVGs to PNG files with transparency?

Since subpixel hinting depends on the order of red, green and blue subpixels, EOG disables it when I use the Save As button. I can take a screenshot, but then I don't have transparency in my images. Is there any piece of software that can render text to raster images with anti-aliasing and subpixel hinting?

This blog post advises to select File → Save a Copy → Cairo PNG for cairo-based rendering.

If you want to make a copy of them all in to one directory try the following:

sudo updatedb
mkdir $HOME/svg
locate *.svg | awk -F'/' '{X=NF-1;Y=NF-2;Z=NF-3}{ system("cp "$0" '$HOME'/svg/"$Z"\"-\""$Y"\"-\""$X"\"-\""$NF) }'

That will copy all SVG files into an svg folder in your home. You can of course adjust those paths as needed. Since a lot of the System SVG's (Icon sets) are the same name among theme. This will copy them into the SVG folder like so:

This /usr/share/icons/Humanity/actions/22/mail-read.svg becomes ~/svg/Humanity-actions-22-mail-read.svg meaning you can view them in one Nautilus folder without having to traverse often cumbersome directory structures.

Another alternative - to keep all your SVGs in the same location, but have them update when theme icon-sets get updated - would be to symlink them all to that folder. As long as you performed a "Save-As" instead of overwriting icons when working on them:

sudo updatedb
mkdir $HOME/svg
locate *.svg | awk -F'/' '{X=NF-1;Y=NF-2;Z=NF-3}{ system("ln -s "$0" '$HOME'/svg/"$Z"\"-\""$Y"\"-\""$X"\"-\""$NF) }'

To smooth the edges you could create the PNGs 10x larger than your target size, then resize with anti-aliasing to JPG. I have done this using Python and the Python Imaging Library to good effect, but I'm not sure how to do it using other tools.
