[vwnc] CairoDemo 1.2.1 / LibRSVG

Karsten Kusche
Hi there,

i've come across the CairoDemo version 1.2.1 on the public store and i
wanted to try it out. Unfortunately it refers to LibRSVG which is not a
prerequisite and i can't find it in the repository either.

Does anyone know which package includes the LibRSVG, or can anyone
provide that package?

Kind Regards
Karsten

Ok,

Magnus pointed out a nice feature of Store that really helped here:

Store-Menu -> Browse Definitions -> Class named...

there i entered LibSVG and fount that it _was_ part of CairoGraphics. It
got removed in version 48, for undocumented reasons. I've loaded the two
SVG classes and it worked pretty well. Now i have SVG graphics rendered
in a Cairo window.

This well hidden feature of store got me thinking: why isn't that part
of the RB Text-Editor menu? Or the explain dialog?

Regards
Karsten

The reason it got removed was that it's original inclusion was an  
error of sorts. In the early days of Cairo development (the project  
Cairo itself, not the VW binding to it), they flirted with including  
svg capabilities and some of the demos included it. Over time, they  
decided/discovered that SVG really was another "layer", and did not  
belong in Cairo proper. There were a number of outlying reasons as  
well, such as it wasn't being actively developed at the time, had  
different xplatform goals, etc.

The VW binding development, as a result kind of followed the same  
route then. We saw the svg examples in some of the demos, and tried to  
make those work. Eventually learning that the above, that those demos  
were "old". So we removed it.
