Detailed Description

Describes how a series of cubes should be exported.

This container class encapsulates the parameters required to specify how an Isis cube should be exported to a standard image format. This encapsulation is useful to applications like "isis2std" for passing its user parameters down to processing classes such as ImageExporters without needing to create new method signatures that take a growing list of parameters. The ExportDescription contains top-level data about the export as a whole, such as bit type. It also contains a list of ChannelDescriptions, each describing the input cubes, attributes, and DN ranges for a channel of color information (gray, red, blue, green, or alpha).
