Hello Agossa, > the GridCoverage got from VectorToRasterProcess cannot be resampled or > saved to tif. It has no ColorModel. > What's wrong?
Ah, you're quite right. The image backing the output grid coverage doesn't has a null ColorModel. The cause is the flattenXXX methods in VectorToRasterProcess which convert the 4 band ARGB image that the vector data are drawn on into a single band int or float image. A color model could be assigned at that stage but will there always be an appropriate choice ? I'm not clear on that. For instance, see this post on the JAI forum... http://forums.java.net/jive/thread.jspa?messageID=137752𡨘 Although the context for that post is multi-band images, I think the point about the difference between GIS data and graphic images still applies. I'd like to defer to Simone and the other image savvy developers for advice about this.
