Didger imports and exports JP2 JPEG 2000 raster image files. The JPEG 2000 File Interchange Format, .JP2, is a image file format standard with additional wavelet compression techniques. It is a format for exchanging JP2 encoded files compliant with the JPEG Interchange Format standard. This format is based on the ISO standard (ISO 15444/6). JPEG2000 offers both lossless and lossy compression and creates smaller file sizes than JPG exports. The image is also better quality than the traditional JPG format.
Some applications associate spatial reference information (such as projection, datum, and georeference parameters) with bitmap images representing a region of the Earth’s surface. If the program you’re running has spatial reference information to export, the option to save the information will appear on the Spatial References tab when exporting. The GeoJP2 format allows the spatial reference information to be stored in one file, along with the image.
No import options dialog is displayed.
