Bart,

Ah, I didn't realize you were trying to render input rasters to a 24bit
result.  24bit raster input is only supported with GDAL enabled.  But
you should be able to render vector data to png24 without GDAL.

I would add that raster input capabilities are very limited without
GDAL enabled.

Best regards,
