All Implemented Interfaces:

Format

public class ImageMosaicJDBCFormat
extends AbstractGridFormat
implements Format

AbstractGridFormat sublass for controlling ImageMosaicJDBCReader creation.

As the name says, it handles mosaicing georeferenced images and image pyramids, based on tiles stored in a JDBC database.

The stored tiles in the database could have any format jai can decode.

• DefaultParameterDescriptor OUTPUT_TRANSPARENT_COLOR = new DefaultParameterDescriptor("OutputTransparentColor", Color.class, null, null); The default value is white
