In the new symbology, when opening layer properties>Symbol properties, the CPU goes up for several minutes, and the system becomes unresopnsive. From the shell I get several warnings:

Warning: QFont::setPointSize: Point size <= 0 (0), must be greater than 0
Warning: QColor::setNamedColor: Unknown color name 'character_n'
Debug: couldn't create image from  "pastedpic_10102008_233747.png"

yes, I also noticed this recently on trunk/Ubuntu.

Replying to [comment:1 lutra]:

yes, I also noticed this recently on trunk/Ubuntu.

Looks like some of the new SVG symbols produce these errors.

#3 Updated by Giovanni Manghi over 12 years ago

it is possible to reomove this symbol? on slow computers the lag is very annoying.

#4 Updated by Borys Jurgiel over 12 years ago

I can confirm it too. +1 for removing it before the 1.6 release, as it makes the new symbology usage extremaly painful (on Core2Duo/4GB ).

#5 Updated by Martin Dobias about 12 years ago

Recently (cca 2 weeks ago) I have improved the loading time of the symbol properties dialog. Is it acceptable now?

Anyway if there are any svg files that cause troubles, it would be good to repair or remove them.

#6 Updated by Borys Jurgiel about 12 years ago

  • Status changed from Open to Closed
  • Resolution set to fixed

Now everything seems to work. Only opening the SVG marker list for adding one of them as a symbol level takes about a second, but I think it's acceptable. I'm closing the ticket now, please test it and open if necessary.

#7 Updated by Paolo Cavallini about 12 years ago

Tested, it works, thanks.
BTW: how could check which SVG symbol causes problems? Perhaps we should automatically check their validity before the inclusion in the standard set?

#8 Updated by Martin Dobias about 12 years ago

I've committed a further improvement in 34e9fc5b (SVN r14500). Opening symbol properties should be instantaneous now.

The warnings/debug statements in console regarding the SVG files can be ignored.
