I would not worry too much about backward compatibility: they say rsvg "has long been deprecated and replaced by rsvg-convert". So your patch should be fine even on rather old systems. Also rsvg(-convert) is not a hard dependency; if absent I guess texmacs falls back to longer paths suchs as svg->eps->png (if possible, of course).

However, while fixing this we should also address bug #30806, increasing the dpi with an extra -d option

"rsvg-convert -f png -d 300 -o " to from

300 dpi is maybe too high if this is only for on-screen, but on the other hand, as noted in the othe bug report, the required dpi depends on the final size of the image that convert doesn't know about.

I attach a patch which should work with rsvg-convert, but someone has to think how to handle both rsvg and rsvg-convert:

What about backwards compatibility? Does this command rsvg-convert exist in previous versions of the library and does it conflict in any way with the modern one?

I mean: if we must handle several versions, is it "safe" (to a certain degree) to assume that whenever rsvg is present in the path, then we have the old tool and whenever rsvg-convert then the new one?

In this case we need only check for these in the path. However, I don't think it's possible to overload converters in TeXmacs with the current infrastructure, so we cannot just add two converters for the same format with different (:require ) clauses (this feature would probably be suboptimal because most conditions are not mutually excluding, but anyway...).

This bug is originally reported by Michael Biebl [1] . The rsvg tool has long been deprecated and is replaced by rsvg-convert. In a recent upstream commit, rsvg was removed from librsvg package [2].

The calls to rsvg-convert, rsvg are similar except that rsvg-convert requires -o option for the output file name, rsvg does not. For e.g.

> rsvg -w 64 -h 64 foo.svg > foo.png # works
> rsvg-convert -w 64 -h 64 foo.svg > foo.png # FAILS
> rsvg-convert -w 64 -h 64 -o foo.png foo.svg # works

The other parameters (-w,-h,-d,-p,-x,-y,-f) behave the same across the two.

Could you please update the rsvg calls to rsvg-convert?
