Label anchor

[pelord]

Description

When setting an anchor point for a text symbolizer, the geostyler style object property seem to have no effect on text placement.

Expected behaviour

Respect the anchor point of the text symbolizer.

How to reproduce

On https://geostyler.github.io/geostyler-demo/

Load a point example and add this geostyler object

{
  "name": "Basic Circle",
  "rules": [
    {
      "name": "Rule 1",
      "symbolizers": [
        {
          "kind": "Mark",
          "wellKnownName": "circle",
          "color": "#FF00AA"
        },
        {
          "kind": "Text",
          "label": "Your Label",
          "size": 12,
          "anchor": "bottom-left"
        }
      ]
    }
  ]
}

The text symbolizer stay a the same place.

Am I alone to encounter this issue?

Hi @pelord , sorry that we did not yet react to this issue.
You're right the anchor property is not respected by the preview. As the preview is rendered via the openlayers parser this is porbably an issue of the openlayers-parser.

I'll transfer this issue.

After further investigation i can say that there seems to be no equivalent in openlayers for this. So i guess we wont be able to support this. I added the "anchor" to the unsupported properties in #827 .

The is no ways to infer label placement?

[KaiVolland]

The anchor in geostyler-style is described as:

The anchor position of the label referred to the center of the geometry.

After checking out the example the closest we get to this is openlayers textAlign.

This would at least have support for 'center' | 'left' | 'right'.
