Currently we only plan on supporting vector data. If you see the need for raster data please enter a request with Esri technical support or on the ArcGIS Ideas site (http://ideas.arcgis.com/). Please provide the business justification for raster data support being added to the File Geodatabase API. Please include an example of the typical workflows where raster support is required.
Thanks for the tip. I have done as you asked. The documentation says rasters will be in future releases, but your comment here suggest otherwise. This is a bit confusing. I am sure many folks are patiently waiting for raster support in the new version
Thank you for posting your request to the Ideas site. We do not have any near-term plans to add support for raster access, but we do closely watch the votes that requests for new functionality get on the Ideas site. Please add a business justification and/or possible workflows to your Idea site posting.
