◆ getBandSelectableImageHandler()

ossimRefPtr< ossimImageHandler > ossimBandSelector::getBandSelectableImageHandler ( ) const

protected

Finds and returns band selectable image handler.

To get a valid pointer there must be one and only one image handler on the input connection and it must be a band selector. In other words, must be a single image chain input and ossimImageHandler::isBandSelector() must return true.

Returns: Pointer to image handler wrapped in an ossimRefPtr on success; null, on error.

GP: We will only allow the immediate input check for an image handler and if one is present then check if selectable

◆ getNumberOfInputBands()

Returns the number of input bands.

Overrides ossimImageSourceFilter::getNumberOfInputBands to check for a single image chain band selectable image handler on the input. If one is present it returns it's number of input bands instead of the number of the input connection's output bands(our input). This is needed so callers, e.g. band selector dialog box can query the number of bands available.

Returns: Number of bands available.

◆ setOutputBandList()

void ossimBandSelector::setOutputBandList	(	const vector< ossim_uint32 > &	outputBandList,
		bool	disablePassThru = `false`
	)

virtual

Sets the output band list.

Parameters

outputBandList	List of zero based bands.
disablePassThru	If true, forces the band selection to be performed by this filter. Otherwise, the image handler to the left is directed to select bands if it has that capability (default behavior).

Note: The input connection should be established prior to calling this.; Bands can be duplicated. So if you have a single band input you can do a band list like "1, 1, 1". Any band within the list must be available from the input. So if you have a 3 band input bands must be constrained to zero based bands "0, 1, or 2".; Calling this method does not enable filter so callers should do: theBandSelector->enableSource(); theBandSelector->setOutputBandList(bandList);

◆ setProperty()

void ossimBandSelector::setProperty ( ossimRefPtr< ossimProperty > property )

Override base class so that a disableSource event does not reinitialize the object and enable itself.

Reimplemented from ossimImageSourceFilter.

◆ setThreeBandRgb()

void ossimBandSelector::setThreeBandRgb ( )

virtual

Will set to three bands (rgb) out.

This will attempt to auto detect the zero based rgb band order from the input image handler. If the result is < 3 bands we will not increase the band output by adding more bands. For example,
if the input is grey or thermal then it will just output one band for a default allocation. Note, this can be overriden by explicitly setting the output band list.
If the image handler implemented getRgbBandList(...) it will use that: bands = 2,1,0 ( or whatever handler thinks rgb is ) else if 3 band or greater and can't determine rgb: bands = 0,1,2 else (less than three bands) bands = 0
