◆ exportImage()

bool G4OpenGLViewer::exportImage	(	std::string	name = `""`,
		int	width = `-1`,
		int	height = `-1`
	)

virtualinherited

Export image with the given name with width and height Several cases : If name is "", filename will have the default value If name is "toto.png", set the name to "toto" and the format to "png". No incremented suffix is added. If name is "toto", set the name to "toto" and the format to default (or current format if specify). Will also add an incremented suffix at the end of the file
