The code writing out the format is very different in these three formats, PNG writes using Java2D, PDF using iText and SVG using Batik. > Geoserver version is 2.14.0. > Stack trace is here : https://pastebin.com/EHq0Lmau >From the trace I see: 1. Caused by: java.lang.NullPointerException 2. at org.apache.batik.svggen.ImageHandlerBase64Encoder.encodeImage(ImageHandlerBase64Encoder.java:157) 3. at org.apache.batik.svggen.ImageHandlerBase64Encoder.handleHREF(ImageHandlerBase64Encoder.java:133) 4. at org.apache.batik.svggen.DefaultImageHandler.handleImage(DefaultImageHandler.java:91) 5. at org.apache.batik.svggen.SimpleImageHandler.handleImage(SimpleImageHandler.java:126) 6. at org.apache.batik.svggen.SVGGraphics2D.drawRenderedImage(SVGGraphics2D.java:1023) 7. at org.geotools.renderer.lite.StyledShapePainter.renderImage(StyledShapePainter.java:747) 8. Making a guess, maybe the style is pointing to an image that cannot be located, and SVG will throw an NPE instead of silently skipping it? Or, if this is the actual code (lines number might not match, but it seems they do) it could be that for some reason Batik is not finding a PNG encoder (the writer variable), but I would not know why or how: https://github.com/apache/batik/blob/trunk/batik-svggen/src/main/java/org/apache/batik/svggen/ImageHandlerBase64Encoder.java#L152 This would need someone running a debugger inside the Batik encoding (and possibly initialization of that registry) and figure out what happened. A first step would be to open a bug report on Jira with reproducible steps (including data and style needed). Also, make sure you've tried the generation on the latest stable version (2.14.1) as we have been upgrading Batik a few times recently.
