svg displays wrongly in map paint style (transform matrix)

[SanderH]

What steps will reproduce the problem?

1. Configure paint style ​http://duinoord.home.xs4all.nl/OSM/JOSM/NL_traffic_signs/Styles_Traffic_signs-style.mapcss
2. Load this part of the map into JOSM: ​http://www.openstreetmap.org/#map=17/51.45683/3.88451
3. Look at the rendered icons for node: 311166052, 3167097354, 3167412965

What is the expected result?

At the position of the nodes with the tag traffic_sign=NL:L1030 an icon is displayed, representing a white circle with a red border and the picture of a dog inside.
​http://duinoord.home.xs4all.nl/OSM/JOSM/NL_traffic_signs/traffic_signs/NL/NL_L1030.svg

What happens instead?

The circle with the red border is displayed correctly, but the dog is displayed only partly (only the dogs back is displayed in the bottom right corner.

Please provide any additional information below. Attach a screenshot if possible.

It appears that the svg renderer within JOSM cannot handle the

   <g id="g3809" transform="matrix(0.13389816,0,0,0.18045415,21.156818,24.705262)">

within the svg which should scale that part of the svg down and reposition it in the center of the icon.
Other applications (Chrome, Firefox, IE, Inkscape) properly display the image.

I don't see what the problem is. The icons are correctly displayed, although being rotated to follow the orientation of the way. Could you please attach a screenshot?

currently displayed

should be displayed

Attached 2 screenshots with how JOSM currently displays the icon and an manually modified version of how JOSM should display the icon.

Mmmm it still works for me, maybe it's a strange combination of map paint styles?

[SanderH]

OK, I think I get to understand why it fails. I was updating the image to add the dog. JOSM does some caching to the images and doesn't detect changes directly when resources are on the internet. In the earlier stages of developing the style was stored locally, JOSM immediately refreshes the display.

Until now I tried removing the paint style, restarting JOSM and adding the paint style to see if that might resolve it. But apparently the old cached icon wasn't purged from cache when the associated paint style was removed.
Now I looked up the cache folder, deleted the icon (luckily it's easily recognisable) and it's now displaying OK after JOSM has downloaded a fresh copy.

I was not looking for an option to easily purge the download cache, but apart from the 'Flush tile cache' I don't see an option for that. I guess I'll have to do it manually then.

This was user error unfortunately. Thanks for the prompt responses and sorry for bothering you.

You're welcome :) Nice you have found the bug, your icons are great by the way :)
