LIBKML: units for style should be set to pixel

[assefa]

When using the libxml driver some style elements (such as the width in a Pen tool) should have the units set to pixel (instead of the default, which I believe is mm). Something like this should be the expected result: PEN(c:#FF00007F,w:4.000000px)

Without the unit element, I run into issues when trying to use MapServer with OGR (and auto styling).

patch for the pen tool (partial patch)

[assefa]

I have applied the partial patch to allow unit settings on pen tools. With that change I was able to dsiplay the my kml properly in MapsServer. I believe it also make sense to do it on the symbol tool but I have not yet tested it.

pen style is supposed to default to pixel width, but apparently this is not the case?

Pen Width - Expressed in a valid unit type (g, px, pt, mm, cm, in) Suggested default: 1 pixel Examples: PEN(c:#FF0000,w:5px), PEN(w:3pt), PEN(w:50g)

assefa I would be interested in seeing what you come up with for point style

if your tests are decent please file another ticket

Thanks Brian

[assefa]

Thanks. I will report on symbols or other things as I continue using the driver.
