Subject: Pixel specification for ascent in image descriptors
Date: Fri, 19 Jul 2024 13:35:49 +0000	[thread overview]
Message-ID: <CAP0Bsmd_VoS9LnWh9kQKGzA0GK22HyZOawcDVbmqUYWY4=P=Xg@mail.gmail.com> (raw)

I am working on a package which requires overlaying some glyphs with an svg
image.  This image should appear as the original glyph, but may be taller
than one as I am rendering small indicators above them.  To appear as the
regular glyph, I need to specify the :ascent image property to be the same
as for the glyph it replaces.  However, this seems to only be possible to
do as a fraction of the image height (expressed as an integer percentage).
This seems to sometimes cause small jitters from off-by-one pixel errors.

Is it possible to specify the ascent of the image in the amount of pixels
instead, similar to how one can with pixel specifications for spaces?
