Member Typedef Documentation

typedef std::map<String,bool> casa::ColormapDefinition::colormapnamemap

Return the names of the built-in colormaps.

If uniqueonly is True (default), only the names of the unique colormaps are returned, otherwise all colormap names are returned.

Constructor & Destructor Documentation

casa::ColormapDefinition::ColormapDefinition ( )

Construct a single color (white) Colormap.

casa::ColormapDefinition::ColormapDefinition ( const String & mapName ) [explicit]

Construct the known Colormap mapName, first looking for a saved Colormap having this name, then resorting to a built-in Colormap, and if that doesn't exist, throw an error.

casa::ColormapDefinition::ColormapDefinition	(	const String &	mapName,
		const Vector< Float > &	reds,
		const Vector< Float > &	greens,
		const Vector< Float > &	blues
	)

Construct a new Colormap, using the supplied name and component vectors.

void casa::ColormapDefinition::getValue	(	const Float	t,
		Float &	red,
		Float &	green,
		Float &	blue
	)		const

Obtain the Colormap value for the "index" value 0 <= t <= 1

Bool casa::ColormapDefinition::loadBuiltinColormap ( const String & name )

Bool casa::ColormapDefinition::loadColormap ( const String & name )

Load Colormap definitions for a specified colormapname

static void casa::ColormapDefinition::loadColormapTable ( ) [static, private]

load ColormapDefinitions from default location aips++/data/colormaps/default.tbl and/or location specified in display.colormaps.usertable

Bool casa::ColormapDefinition::queryColormapTable	(	const Table &	table,
		const String &	name
	)		`[private]`

Utility function to look if a colormap name is in a Table.

Bool casa::ColormapDefinition::save	(	const String &	fullPathName,
		const Vector< String > &	synonyms,
		const Bool &	overwrite = `True`
	)		const

Write this ColormapDefinition to the named Table in the named directory (default values are obtained from the user's .aipsrc file.

If overwrite is True, then an existing map of the same name in the Table will be over-written. If the named Table does not exist, it will be created.

The table format has to conform with following scheme. It must have five columns: CMAP_NAME a String RED a Float array of dim n GREEN a Float array of dim n BLUE a Float array of dim n SYNONYMS a String array of dim m
