I think it would be worth a try to use the SVG symbols directly - or at
least offer the option to use them.

Scaling SVG in Inkscapes is known to be problematic. Are you sure

this applies to Qt SVG scaling too?

Hi Andreas,
I made fast SVG downscaling test. Rendered with Inkscape.
Second column is shifted vertically by 0,5px.
As you can see main problem is "travelling blur" effect. Perhaps
there are some smart renderers to overcome this.
I would also like to have just one SVG file...

Hi Robert,
Thanks for the reply.
Do you have a side-by-side comparison of SVG vs. png and the
rendering
quality somewhere? I wonder if this is still an issue and if it
is - how
much of a problem it really is.
Having just one icon size instead of n different sizes also has a
lot of
advantages. Think about all the new high-dpi devices. These would
benefit a lot from SVG instead of PNG.

Regarding the discussion around the icons?
How about using SVG icons instead of fixed size png icons?
That way one
could easily scale the icon sizes on different devices to the
preferred
scale and taste of the user.
From my test and literature I found that simple vector scaling
for
small size icons (16x16 - 24-24) is not recommended. For higher
images
blur effect is not so visible and important.
Are there any technical reasons for using PNGs instead of
SVGs? I
believe the source of the icons is SVG anyway?
For my own in house python plugins I always use the SVG
icons.
The main technical reason was image quality. We decided to use
already rendered images in "native resolution". I know it
sounds
stupid in Scalable Vector ... context, but that's the reality.
Whole version 0.1 of GIS icons was designed in just one SVG
file. In
version 0.2 I save them in separate files. So most of the icons
is at
the moment available as one file per icon.
regards,
Robert
