Detailed Description

The vpDisplayOpenCV allows to display image using the opencv library.

The example below shows how to display an image with this video device.

#include <visp/vpConfig.h>
#include <visp/vpImageIo.h>
#include <visp/vpDisplayOpenCV.h>
#include <visp/vpImagePoint.h>
int main() 
{
#if defined(VISP_HAVE_OPENCV)
  vpImage<unsigned char> I; // Grey level image
  // Read an image in PGM P5 format
  vpImageIo::read(I, "/local/soft/ViSP/ViSP-images/Klimt/Klimt.pgm");
  vpDisplayOpenCV d; 
  // Initialize the display with the image I. Display and image are
  // now link together.
  d.init(I);
  // Specify the window location
  vpDisplay::setWindowPosition(I, 400, 100);
  // Set the display window title
  vpDisplay::setTitle(I, "My OpenCV display");
  // Set the display background with image I content
  vpDisplay::display(I);
  // Draw a red rectangle in the display overlay (foreground)
  vpDisplay::displayRectangle(I, 10, 10, 100, 20, vpColor::red, true);
  // Draw a red rectangle in the display overlay (foreground)
  vpImagePoint topLeftCorner;
  topLeftCorner.set_i(10);
  topLeftCorner.set_j(50);
  vpDisplay::displayRectangle(I, topLeftCorner, 100, 20, vpColor::green, true);
  // Flush the foreground and background display
  vpDisplay::flush(I);
  // Get non blocking keyboard events
  std::cout << "Check keyboard events..." << std::endl; 
  char key[10];
  bool ret;
  for (int i=0; i< 200; i++) {
    bool ret = vpDisplay::getKeyboardEvent(I, key, false);
    if (ret) 
      std::cout << "keyboard event: key: " << "\"" << key << "\"" << std::endl;
    vpTime::wait(40);
  }
  // Get a blocking keyboard event
  std::cout << "Wait for a keyboard event..." << std::endl; 
  ret = vpDisplay::getKeyboardEvent(I, key, true);
  std::cout << "keyboard event: " << ret << std::endl;
  if (ret) 
    std::cout << "key: " << "\"" << key << "\"" << std::endl;
  
  // Wait for a click in the display window
  std::cout << "Wait for a button click..." << std::endl;
  vpDisplay::getClick(I);
#endif

Constructor & Destructor Documentation

vpDisplayOpenCV::vpDisplayOpenCV ( )

Basic constructor.

To initialize the window position, title and size you may call init(vpImage<unsigned char> &, int, int, const char *) or init(vpImage<vpRGBa> &, int, int, const char *).

#include <visp/vpDisplayOpenCV.h>
#include <visp/vpImage.h>
int main()
{
  vpDisplayOpenCV d;
  vpImage<unsigned char> I(240, 384);
  d.init(I, 100, 200, "My display");
}

Definition at line 164 of file vpDisplayOpenCV.cpp.

vpDisplayOpenCV::vpDisplayOpenCV	(	int	x,
		int	y,
		const char *	title = `NULL`
	)

Constructor that just initialize the display position in the screen and the display title.

Parameters

x,y	: The window is set at position x,y (column index, row index).
title	: Window title.

To initialize the display size, you need to call init().

#include <visp/vpDisplayOpenCV.h>
#include <visp/vpImage.h>
int main()
{
  vpDisplayOpenCV d(100, 200, "My display");
  vpImage<unsigned char> I(240, 384);
  d.init(I);
}

Parameters

I	: Image to be displayed (not that image has to be initialized)
x,y	: The window is set at position x,y (column index, row index).
title	: Window title.

Constructor. Initialize a display to visualize a RGBa level image (32 bits).

Parameters

I	: Image to be displayed (not that image has to be initialized)

bool vpDisplayOpenCV::getClick ( bool blocking = true )

protectedvirtual

Wait for a click from one of the mouse button.

Parameters

blocking

[in] : Blocking behavior.

When set to true, this method waits until a mouse button is pressed and then returns always true.
When set to false, returns true only if a mouse button is pressed, otherwise returns false.

Returns

true if a button was clicked. This is always the case if blocking is set to true.
false if no button was clicked. This can occur if blocking is set to false.

Wait for a click from one of the mouse button and get the position of the clicked image point.

Parameters

ip	[out] : The coordinates of the clicked image point.
blocking	[in] : true for a blocking behaviour waiting a mouse button click, false for a non blocking behaviour.

Returns

true if a button was clicked. This is always the case if blocking is set to true.
false if no button was clicked. This can occur if blocking is set to false.

blocking	[in] : Blocking behavior. When set to true, this method waits until a mouse button is pressed and then returns always true. When set to false, returns true only if a mouse button is pressed, otherwise returns false.

Returns

true if a button was clicked. This is always the case if blocking is set to true.
false if no button was clicked. This can occur if blocking is set to false.

bool vpDisplay::getClick	(	const vpImage< unsigned char > &	I,
		vpImagePoint &	ip,
		bool	blocking = `true`
	)

staticinherited

Wait for a click from one of the mouse button and get the position of the clicked image point.

Parameters

I	[in] : The displayed image.
ip	[out] : The coordinates of the clicked image point.
blocking	[in] : Blocking behavior. When set to true, this method waits until a mouse button is pressed and then returns always true. When set to false, returns true only if a mouse button is pressed, otherwise returns false.

Returns: true if a mouse button is pressed, false otherwise. If a button is pressed, the location of the mouse pointer is updated in ip.

Warning: This method is not yet implemented.

Set the font used to display a text in overlay. The display is performed using displayCharString().

Parameters

font	: The expected font name. The available fonts are given by the "xlsfonts" binary. To choose a font you can also use the "xfontsel" binary.

Note: Under UNIX, to know all the available fonts, use the "xlsfonts" binary in a terminal. You can also use the "xfontsel" binary.
