Description: Since the installation of MapServer version 8.6.0, SVG symbol processing no longer yields the expected results when rasterized.
Observed Behavior:
- The anomaly is visible during rendering via OpenLayers and when exporting to image formats (JPEG).
- Interestingly, when the map is exported to PDF format, the symbols are processed correctly.
- It appears that the symbol is not being resized correctly during the rasterization process.
Environment & Versioning: Tests were performed on the same machine (Ubuntu 24.04) using compiled versions of MapServer. Rolling back to version 8.4.1 restores the expected behavior.
Output of mapserv -v:
