transform statement

[UlrichRe]

Hi Jeroen,

thank you for your work. I would like to use rsvg to convert an svg character string to a pdf file, but it looks to me that there is an issue with inner nodes transform statements.

F.i. look in the attached example svg.test.pdf at value 8,4 of node 'RND (Plan) [J]'. Value 8,4 should be right-aligned in column 'Total', but it is displayed too far left. File svg.test.pdf was generated by rsvg from svg character string in file svg.test.txt. file svg.test.safari.pdf was generated from svg.test.txt in Safari and looks correct. ( svg.test.txt also is presented correctly in Chrome.)

Regards, Ulrich

You have to ask rendering questions to the librsvg folks: https://wiki.gnome.org/LibRsvg. The R package only has bindings to librsvg2, it does not actually implement the rendering. I suspect that your svg file is malformed in some way though.

Hi Jeroen, thank you for your reply!  Regarding your suspect that the svg file is malformed:

• I copied the file 'svg test.txt' into webStorm (File -> New ... -> HTML file) and it showed up correctly in Chrome. See attachment 'Bildschirmfoto 2016-11-28 um 18.08.22.png'

• Then I left out a couple of unnecessary instruction in that file. Thus you can check rather easily the simplified file 'svg test02.html' in the attachment. The svg data is shown correctly shown in Safari and Chrome, but not in the attached file 'svg test02.pdf' which is generated by the attached R program 'svg test02.R' which uses package rsvg.

• I generated the svg file basically using d3.

Do you still think it is just a question of rendering which has to be addressed to the librsvg folks? Best regards,Ulrich

Yes you will have to ask this on the librsvg mailing list or bug tracker. The R package only has a bindings, it does not control the rendering in any way...

[UlrichRe]

ok, thanks for your hint.I reported an issue: Bug 775350 – incorrect text alignment in the rendering of an svg tree Regards,Ulrich

Hi Jeroen, there is a question from the librsvg folks:  André Klapper 2016-11-29 16:37:38 UTC Which exact librsvg version is used? https://bugzilla.gnome.org/show_bug.cgi?id=775350 Regards,Ulrich

Which operating system do you use? On Windows the package uses librsvg-2.40.16. On other systems it depends on what is installed on your system. But I think this problem appears with the latest version as well.

I am using macOS Sierra.

Do you have homebrew installed on your system?

[UlrichRe]

no, should I install homebrew?

That way you can controll the version of librsvg yourself. So you can do:

brew install librsvg

And then in R:

install.packages("rsvg", type = "source")

[UlrichRe]

Thanks.I installed librsvg-2.40.16_1 and reinstalled rsvg. PDF-output is stillthe same.

Note that the librsvg from brew also comes with a handy command line utility rsvg-convert. You can use this to convert the svg to png via the command line, to rule out a problem in R:

rsvg-convert svg.test.txt > out.png

[UlrichRe]

Is there also a way to convert directly from svg to pdf without using R?

Yes, try this

rsvg-convert svg.test.txt -f pdf -o test.pdf

[jeroen]

I am closing this issue here because this is a problem in librsvg that also happens without R.
