Putting Graphic in TextSymbolizer of Geoserver SLD Style

Question

I tried to add external graphic element in TextSymbolizer of point layer as Geoserver 2.19, I got the following result

<?xml version="1.0" encoding="UTF-8"?>

Is there any workaround to fix offset label from the graphic symbol?

Answer 1

What you are trying to do is usually solved using the label-obstacle vendorOption which is applied to a vector symbolizer to tell the label drawing code to avoid those features.

There is a detailed example in the GeoServer manual.

However, you could probably make your way work if you set displacement to be a simple negative Y (so you place the label below the graphic) with the anchor at the top middle of the label (X=0.5, Y=1) and remove the <se:VendorOption name="maxDisplacement">10</se:VendorOption> line as that allows the labelling code to move the label about (undoing the control you had). But you will have to move the graphic to a PointSymbolizer other wise it will always be drawn under your label (as that is the purpose of the graphic in a TextSymbolizer).
