@RazrFalcon Sorry for suggestion other software in your project, but I recommended svgcleaner very often on other projects.

leeoniya commented 4 years ago

+1 for flattening transforms. a lot of svg editors leave them in - sometimes many nested layers of them.

RazrFalcon commented 4 years ago

In most cases you cannot do this (due to referenced paint servers) or it will make the file bigger. So the current algorithm is working correctly. The problem is that it's mostly useless.

@JoKalliauer I don't mind, especially since svgcleaner is dead for now.

that's too bad :(

i haven't found any better alternatives. any recommendations? i've used svgo, and like that i can reduce numeric precision, but i know that's antithetical to this project. either way, i think svgcleaner is better and faster at structural simplification than svgo (which this issue touches on).

RazrFalcon commented 4 years ago

any recommendations?

Only time. Eventually I will find the time to rewrite it.

JoKalliauer commented 4 years ago

@lencioni : As long as SVG1.1 is the golden standard not developed svg-optimizers don't get outdated (that fast).

At https://commons.wikimedia.org/wiki/User:JoKalliauer/Optimization#Using_Optizatiors I discuss several optimizers. The three comon comand-line svg-optimizers/cleaners/scubbers are svgcleaner,svgo,scour but none of them is developed actively any more see https://commons.wikimedia.org/wiki/Help:SVG#Tidying_up for references (Refs [16,17,18]).

If you do not want to wait, I see three more soulutions

  1. You could donate to inkscape (for scour) or to svgo or hire RazrFalcon (for svgcleaner). (I would guess if you donate ~10€/hour it will be implemented quite fast.)
  2. You code it yourself and make a pull-request. (That's maybe the most expensive option, since time is imho expensive.)
  3. You hire someone else to make a pull-request. ( I would guess you have to pay ~70€/hour (for an unexperienced austrian developer). )
