Function Documentation

display() [1/4]

bool drawingHelpers::display	(	VISP_NAMESPACE_ADDRESSING vpImage< double > &	D,
		const std::string &	title,
		const bool &	blockingMode
	)

display() [2/4]

void drawingHelpers::display	(	VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &	I,
		const std::string &	title
	)

Display a gray-scale image.

Parameters

[out]	I	The gray-scale image to display.
[in]	title	The title of the window.

Examples

tutorial-canny.cpp, and tutorial-circle-hough.cpp.

display() [3/4]

bool drawingHelpers::display	(	VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &	I,
		const std::string &	title,
		const bool &	blockingMode
	)

display() [4/4]

bool drawingHelpers::display	(	VISP_NAMESPACE_ADDRESSING vpImage< VISP_NAMESPACE_ADDRESSING vpRGBa > &	I,
		const std::string &	title,
		const bool &	blockingMode
	)

init()

void drawingHelpers::init	(	VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &	Iinput,
		VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &	IcannyVisp,
		VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > *	p_dIx,
		VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > *	p_dIy,
		VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > *	p_IcannyimgFilter
	)

Initialize the different displays.

Parameters

[out]	Iinput	Input image of the program.
[out]	IcannyVisp	Image resulting from the vpCannyEdgeDetection method.
[out]	p_dIx	If different from nullptr, pointer towards the gradient along the horizontal axis.
[out]	p_dIy	If different from nullptr, pointer towards the gradient along the vertical axis.
[out]	p_IcannyimgFilter	If different from nullptr, pointer towards the result of the vpImageFilter::canny method.

Examples

tutorial-canny.cpp.

waitForClick()

bool drawingHelpers::waitForClick	(	const VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &	I,
		const bool &	blockingMode
	)

Catch the user clicks to know if the user wants to stop the program.

Parameters

[in]	I	The gray-scale image to display.
[in]	blockingMode	If true, wait for a click to switch to the next image.

Returns

true The user wants to continue the application.

false The user wants to stop the application.

Examples

tutorial-canny.cpp.
