QSvgWidget not displaying file completely
-
Hi
Qt only supports a subset of SVG. called mini or something like that.
It might be its simply not support if it uses something advanced.@mrjj said in QSvgWidget not displaying file completely:
called mini or something like that.
You make me curious. So I looked into the doc. It's called Tiny :)
Qt supports the static features of SVG 1.2 Tiny. ECMA scripts and DOM manipulation are currently not supported.

Well, that's disappointing,.. I wasn't expecting that. I guess I will have to abandon the idea of using SVG after all.
Thanks to both of you.

Yeah it kinda sucks since it just looks like some text etc so I would have guessed it was covered by the Tiny specs.Could i get the image to have a look at?

Hi
It seems the texts are not real text objects but some sort of path pr letter. (maybe the glyphs)Maybe there is some options in Cairo package that allows to use text object instead ?

and https://cran.r-project.org/web/packages/svglite/index.html
can be used to export as text but not sure it fit rest of your use case :) -

My knowledge of graphics files, including SVG, is next to non-existant, so I wasn't exactly shocked. Furthermore, just thinking about something called vector graphics, the ignorant me imagines that the file does not contain letters but relative positions of pixels or whatever... I'd better shut up, because I don't know what I am talking about haha.

@mrjj Ok, I will have a look. I have already produced PNG files and will be working with them, unless I find a solution that will give me SVG in Qt without much extra work.
Thank you a lot, either way. :)

Hi
Well a hires PNG should also work nicely.
Just for info. SVG is vector which means its not pixels but drawing functions so it can scale
without becoming pixellated. However, Cairo seems to not excatly insert the letters as letter but some form of another drawing thing that Qt cant draw.SVG would look better if you were to print it on really hires printer or in A3 but in other cases, the PNG will look just as fine if you make sure its not lowres.

Just in case somebody stumbles upon this thread and also tried to use the Cairo SVG package with QSvgWidget - forget about Cairo as nice as it sometimes could be, as there is an R package ggiraph with a simple function dsvg(filename,...) and it produces a SVG file that is fully supported by Qt.
