Did you set a feature color to the vertex? Is required.

If you need to create a single-band raster based on 3D points, consider using the NumericRasterizer.

ImageRasterizer requires a color value. You can use FeatureColorSetter.

As @takashi said the NumericRasterizer only requires a z value. Should work for you.

 

Your error log can not be opened by me.

I always think MapnikRasterizer is an easy to use transformer for creating raster from vector (and/or raster).
