Not really, well, they might need to be PNG's to work the way Leo uses
them, but from the point of view of generating them with the script, no.

The script really does two things, runs a loop with these values:

(0, ('clean', 'no_clone', 'unmarked', 'empty'))
(1, ('clean', 'no_clone', 'unmarked', 'content'))
(2, ('clean', 'no_clone', 'marked', 'empty'))
(3, ('clean', 'no_clone', 'marked', 'content'))
(4, ('clean', 'clone', 'unmarked', 'empty'))
(5, ('clean', 'clone', 'unmarked', 'content'))
(6, ('clean', 'clone', 'marked', 'empty'))
(7, ('clean', 'clone', 'marked', 'content'))
(8, ('dirty', 'no_clone', 'unmarked', 'empty'))
(9, ('dirty', 'no_clone', 'unmarked', 'content'))
(10, ('dirty', 'no_clone', 'marked', 'empty'))
(11, ('dirty', 'no_clone', 'marked', 'content'))
(12, ('dirty', 'clone', 'unmarked', 'empty'))
(13, ('dirty', 'clone', 'unmarked', 'content'))
(14, ('dirty', 'clone', 'marked', 'empty'))
(15, ('dirty', 'clone', 'marked', 'content'))

and demonstrates their use to make simple 4-color square PNGs using
PIL.  But you could certainly use that loop to generate SVG files in
various ways, maybe hiding / showing pre-drawn elements in an SVG file.

Still the SVG files may need to be rendered to a bitmap format for Leo
to use them, but that's a separate issue.

Do the icons have to be .pngs? I had to make something similar a while ago 
and ended up using  svgwrite to create .svg files,
and then converting these to .png files. This was the best quality route 
for my purposes. If Qt can accept .svg icons directly they
might come out nicer, in case this makes any difference.

color icons

[Terry Brown]

https://github.com/leo-editor/snippets/blob/master/examples/tests/make_icons.py

make the simple icons attached.  Intended for dark rather than light
background.  Might be useful for other automated icon generation
things, seeing it iterates the 16 states in the correct 00..15 order.

Maybe it could be added to .../leo/extensions/

Still "eating my own dog food" to see if I actually like the icons.  I
went with an indicator for nodes with no content, rather than an
indicator for nodes with content, seeing the latter's more common and
I'm not really sure how important that indicator is anyway... maybe
I'll try not indicating that state.  Of course then there's a wasted
slot in my 2x2 icon design :-)

Cheers -Terry
