Do we have existing use cases where existing articles rely on them to have white background?

Unknown.  I don't think this is known.  We could change it and wait for people to complain.  Alternatively, I'm pinging Brandon in case he has some input.

All hieroglyphs images are under wikihiero/img directory.
If someone can adding transparency using a script, you are welcome.

Alternate wikihiero images with (more or less) transparent backgrounds

Script to remove white background from behind hieroglyphs:

#!/bin/bash
for f in img/*
do
	echo "Editing $f .. "
	convert $f -background none -fuzz 10% -transparent white -flatten $f
done

an image of a hieroglyph on grey background

This is how the suggested image looks on a grey background.

The images aren't great quality, so editing them is a bit of a hack to begin with.

Some other ideas:
* Just extracting the black-ness, then dropping it on a transparent background. There would be no artefacts, but the pixels would be even more visible than they are currently.
* Re-generating them all from a free font (such as Aegyptus as found in Debian's ttf-ancient-fonts) on a transparent background. This is probably preferable in the long-run.

I've redone this doing the transparency properly; see https://gerrit.wikimedia.org/r/#/c/63363/ in gerrit.
