Re: [Inkscape-devel] Icon sizes

Indeed that solves the scaling issue (well sort of, since rendering
the vectors at a size they were not intended for makes them look
funny, but that's a whole other debate).
Not following sizing from the GTK+ theme settings is one key thing
that the external icons are blocking.
The good news, however, is that the changes Krzysztof did included
one that cleared the last bugs complicating external themes. So now
all those files that are under "hicolor" can be dropped in to user
directories or system ones as an external theme. So now these can be
delivered independent of the official Inkscape release install.
I guess by "external icons" you mean getting them from a directory
with bitmap icons at different sizes, as all other GTK apps do. So, if
I understand correctly, removing the hicolor dir (hence the external
icons) falls back on rendering them on the fly from the SVG source (as
was done before). This currently has several "drawbacks":
- it uses the old icon theme, not the new tango-like one on which many
people worked to make it better. I don't want to start another
flamewar between tango/old theme, but I am just saying that switching
from one icon rendering method to the other should not change the theme.
- it adds a lag to startup: 6-7 seconds with external icons, 11-12
without. And this is increased when the rest of the machine is busy
already. I understand that icons have to be rendered from the SVG but
was there not some kind of caching that Mental introduced? Doesn't it
persist between startups?
So for both compatibility purposes (with the regular theming mechanism
of GTK apps) and from a performance point of view, external icons seem
better. The drawback is that they put more strain on the icon
designers. But there is some kind of script that should allow to
export all icons at all sizes from a common document by leveraging the
export all groups feature of Inkscape.
So then, what is needed to have the external icons work properly?
"Just" design some at bigger sizes (32 and 48) and export them
together with the currently existing sizes (24, 16) in hicolor? If the
tango icons look good as they are, then I guess the people that worked
on them could scale and touch them up a bit at these large sizes to
complete the icon set.
[Note: I am perfectly happy with 24 and 16 because we ship with a
custom theme on OS X and I can set the sizes there (and I have a small
screen so 24 and 16 are nice). But I guess people with external GTK
themes and/or big screens might what bigger ones]
