very slow to render #10

Closed keturn closed 3 weeks ago

It is very slow to open chapters and pages of this (kepub) on my Kobo Clara HD. Long enough that I thought it had completely frozen the device at first. Given that loading https://github.com/standardebooks/lewis-carroll_through-the-looking-glass_john-tenniel/blob/master/src/epub/images/illustration-2.svg severely lags my chromebook for at least a good five seconds or so, I think it's pretty safe to blame the large SVGs.

How were they vectorized? Is there a way to slim them down?

Yes, the SVGs are quite large. Open to suggestions on ways to slim them down.

I've turned up a couple packages that might be relevant:

But I think that before we go trying to wrangle these generated svg files to something manageable, it could be worth re-examining how they were generated in the first place. Are there parameters on that end for adjusting the number or complexity of the paths it spits out?

acabal commented 6 months ago

They were generated a long time ago and I don't remember how. Probably using trace path in Inkscape. I don't think how they were generated matters that much, if some tool can compress them without much or any fidelity loss, or if someone can recreate them in some better way.
