◆ saveState()

bool ossimGpkgReader::saveState	(	ossimKeywordlist &	kwl,
		const char *	prefix = `0`
	)		const

virtual

Method to save the state of an object to a keyword list.

Return true if ok or false on error.

Reimplemented from ossimImageHandler.

◆ setCurrentEntry()

bool ossimGpkgReader::setCurrentEntry ( ossim_uint32 entryIdx )

Parameters

entryIdx Entry number to select.

Note: The implementation does nothing. Derived classes that handle multiple images should override.

Returns: true if it was able to set the current entry and false otherwise.

◆ setProperty()

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

virtual

Set propterty method.

Overrides ossimImageHandler::setProperty.

Current property name handled: "scale" One double value representing the scale in meters per pixel. It is assumed the scale is same for x and y direction.

Parameters
