Matthew, Neil, and I have been talking about how to resolve the
dependency problem. I think that the our thinking was that the best
plan is to break out a "pict" library that both slideshow and drracket
can safely depend on, and have the icons library depend on that.
Yes. Then DrRacket could build its icons as it currently does, by
combining primitive icons. Updating the primitive icons would only
require changing the SVG sources and re-rendering the PNGs.
We didn't consider putting some of it into 'meta', tho. That makes a
lot of sense to me. Neil, Matthew, how does that sound?
It could be the wrong thing to do in the future.
I don't think it would help much now with size, if that's the issue,
because the SVGs are only 400-800K uncompressed. (As XML, they compress
well.) PNG renderings of the SVG icons in various colors and at various
sizes take up almost all the space, and these have to be in any
distribution that includes icons/main.rkt.
If Racket could render SVGs, we could save space in every distribution,
allow icons to be arbitrarily colorized, and render them at arbitrary
sizes instead of just sizes between 8 and 64. This would also make it
wrong to move the SVGs to `meta'.
I briefly looked into rendering SVGs just now. Apparently, Cairo can't
do it natively. We'd need to use a third-party library like librsvg.
Alternatively, I could make partial support for SVG rendering into a
holiday project, for after the FLOPS deadline. I think our dc<%>s and
brushes can handle everything in the icon SVGs except blur, which isn't
strictly needed.
At any rate, SVG-backed picts would be useful for more than just icons.
Name: I think it is called the icons collection because that's where
the icons were before when Neil generalized things.
Right. The logos were already there.
We could make a
'sprites' collection and then move maybe even move planetcute into
that collection?
I'd be okay with a `sprites' collection: `sprites/planetcute',
`sprites/icons', `sprites/logos', etc.

I agree. It's on my to-do list now.

"magnifying-glass-left-shiny.svg" and
"magnifying-glass-left-diffuse.svg", they are both cropped at the
top (at least the way that they're rendered in Emacs),
That's odd. They shouldn't be. Their page sizes are the same as every
other icon, so I'd say the problem is in whatever library Emacs uses to
render them.
but in
addition they're at different places (which is visible in the PNG
rendered files too). I wouldn't have pointed it out, but it might
be some bug in your rendering script.
I centered the icon using the entire picture, but centering it using
just the magnifying glass (without the handle) is worth trying.
