[Qgis-user] Textual representation of styles ?

Tue Aug 7 23:11:45 PDT 2018

Thanks all,

No, SLD is layer based, and I'm looking into something that's feature based.

As I wrote, I'm aware of SLD (and QGIS' own QML), but that's not what I'm looking for.

Good morning,

Wait, so I can't straight away use an SLD file generated in QGIS for styling my layers in Geoserver? Is there any more info about his somewhere?

Thanking you in advance,

Hi Lars,
Would SLD be what you ar looking for?

http://www.opengeospatial.org/standards/sld

QGIS can save its styles to this format, be aware, its not a full implementation of SLD, so it takes a little tweaking to make it work with other SLD compliant software line GeoServer.
Hope it helps,

Richard.

Hi list.

Does QGIS utilize and support textual styles, e.g. as read from data ?

OGR has a feature style specification (https://www.gdal.org/ogr_feature_style.html ), with some examples shown below.

Has anyone used QGIS to facilitate such style representation ?

Here are some example style definition strings:

  *   A 5 pixels wide red line:
PEN(c:#FF0000,w:5px)
  *   A polygon filled in blue, with a black outline:
BRUSH(fc:#0000FF);PEN(c:#000000)
  *   A point symbol:
SYMBOL(c:#00FF00,id:"points.sym-45,ogr-sym-7")
  *   A text label, taking the text string from the "text_attribute" attribute field:
LABEL(f:"Times New Roman",s:12pt,t:{text_attribute})"
Here is what a style table that contains all the above styles could look like:
    road:      PEN(c:#FF0000,w:5px)
    lake:      BRUSH(fc:#0000FF);PEN(c:#000000)
    campsite:  SYMBOL(c:#00FF00,id:"points.sym-45,ogr-sym-7")
    label:     LABEL(f:"Times New Roman",s:12pt,t:{text_attribute})

I know that QGIS supports its own XML style format, and supports some form of SLD. Both are layer based, though, not feature based.
