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).

Member Function Documentation

◆ addChannel() [1/2]

int Isis::ExportDescription::addChannel ( FileName filename,
CubeAttributeInput & att )

Add an export color channel for the given input cube and attributes (typically band number).

Parameters
filenameThe name of the cube
attThe cube attributes such as band number
Returns
The index of the newly added channel

Referenced by ExportDescription(), and operator=().

◆ addChannel() [2/2]

int Isis::ExportDescription::addChannel ( FileName filename,
CubeAttributeInput & att,
double min,
double max )

Add an export color channel for the given input cube, attributes (typically band number), and input DN range.

Parameters
filenameThe name of the cube
attThe cube attributes such as band number
minThe minimum DN in the input mapped to the minimum of the output
maxThe maximum DN in the input mapped to the maximum of the output
Returns
The index of the newly added channel

◆ channel()

const ExportDescription::ChannelDescription & Isis::ExportDescription::channel ( int i) const

Return the channels description at the given index.

Parameters
iIndex of the desired channel
Returns
Constant reference to the channel

Referenced by ExportDescription(), and operator=().

◆ channelCount()

int Isis::ExportDescription::channelCount ( ) const

Count of the number of channels in the description.

Returns
The channel count

Referenced by Isis::ImageExporter::initializeProcess().

◆ operator=()

ExportDescription & Isis::ExportDescription::operator= ( const ExportDescription & descriptionToCopy)

Assignment operator for the export description.

Parameters
descriptionToCopyExportDescription to be copied.
Returns
ExportDescription with same number of channels, type, and pixel values.
