ICLQt_API void icl::qt::show ( const icl::core::ImgBase & image )

shows an image using TestImages::show

The image is wrote to disk into a temporary file. Then it is shown using a specifi show command, which can be set, using the the showSetup function, which is also available in this package.

Parameters:

image image to show

See also:: showSetput(const string&, const stirng&, int)

ICLQt_API void icl::qt::showSetup	(	const string &	showCommand = `"xv %s"`,
		const string &	rmCommand = `"rm -rf %s"`,
		int	msecBeforeDelete = `500`
	)

setup image visualisation programm

when images are shown using an extrenal viewer like gnu's xv, the image is temporarily written to the hard disk. Then the show command is called. Before the rmCommand is called usleep(1000*msecBeforeDelete); is called, to ensure, that the viewer has read the image completely. By default, the "iclxv" image viewer is used, which is available as example of the ICLQt package. In this case, the showCommand is "iclxv -input %s -delete". As iclxv automatically deletes the image, when it was read, the rmCommand is empty and the wait time is 0. To use this, you have to place at least a link to ICLQt/examples/iclxv into any directory contained in your path variable.
