Detailed Description

The vpDisplayGTK allows to display image using the GTK+ library version 1.2.

The GTK+ 1.2 library has to be available on the system.

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

#include <visp3/core/vpConfig.h>
#include <visp3/io/vpImageIo.h>
#include <visp3/gui/vpDisplayGTK.h>
#include <visp3/core/vpImagePoint.h>
int main() 
{
#if defined(VISP_HAVE_GTK)
  vpImage<unsigned char> I; // Grey level image
  // Read an image in PGM P5 format
#ifdef _WIN32
  vpImageIo::read(I, "C:/temp/ViSP-images/Klimt/Klimt.pgm");
#else
  vpImageIo::read(I, "/local/soft/ViSP/ViSP-images/Klimt/Klimt.pgm");
#endif
  vpDisplayGTK 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 GTK 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(50);
  topLeftCorner.set_j(10);
  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

vpDisplayGTK::vpDisplayGTK ( )

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 <visp3/gui/vpDisplayGTK.h>
#include <visp3/core/vpImage.h>
int main()
{
  vpDisplayGTK d;
  vpImage<unsigned char> I(240,384);
  d.init(I, 100, 200, "My display");
}

Definition at line 170 of file vpDisplayGTK.cpp.

vpDisplayGTK::vpDisplayGTK	(	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 <visp3/gui/vpDisplayGTK.h>
#include <visp3/core/vpImage.h>
int main()
{
  vpDisplayGTK d(100, 200, "My display");
  vpImage<unsigned char> I(240,384);
  d.init(I);
}

vpDisplayGTK::vpDisplayGTK	(	vpImage< unsigned char > &	I,
		int	x = `-1`,
		int	y = `-1`,
		const char *	title = `NULL`
	)

Constructor : initialize a display to visualize a gray level image (8 bits).

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.

vpDisplayGTK::vpDisplayGTK	(	vpImage< vpRGBa > &	I,
		int	x = `-1`,
		int	y = `-1`,
		const char *	title = `NULL`
	)

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

staticinherited

Display an ellipse from its parameters expressed in pixels.

Parameters

I	: Image to consider.
center	: Center of the ellipse.
coef1,coef2,coef3	: Depending on the parameter use_centered_moments these parameters are: the centered moments expressed in pixels: $\mu_{20}, \mu_{11}, \mu_{02}$ ; the major and minor axis lenght in pixels and the excentricity of the ellipse in radians: .
use_centered_moments	: When false, the parameters coef1, coef2, coef3 are the parameters . When true, the parameters coef1, coef2, coef3 are rather the centered moments $\mu_{20}, \mu_{11}, \mu_{02}$ expressed in pixels. In that case, we compute the parameters a, b and e from the centered moments.
color	: Drawings color.
thickness	: Drawings thickness.

All the points $(u_\theta,v_\theta)$ on the ellipse are drawn thanks to its parametric representation:

$\left(\begin{array}{c} u_\theta \\ v_\theta \end{array} \right) = \left(\begin{array}{c} u_c \\ v_c \end{array} \right) + \left(\begin{array}{cc} \cos(e) & -\sin(e) \\ \sin(e) & \cos(e) \end{array} \right) \left(\begin{array}{c} a \cos(\theta) \\ b \sin(\theta) \end{array} \right)$

with $0 \leq \theta \leq 2\pi$ .

staticinherited

Display an ellipse from its parameters expressed in pixels.

Parameters

I	: Image to consider.
center	: Center of the ellipse.
coef1,coef2,coef3	: Depending on the parameter use_centered_moments these parameters are: the centered moments expressed in pixels: $\mu_{20}, \mu_{11}, \mu_{02}$ ; the major and minor axis lenght in pixels and the excentricity of the ellipse in radians: .
theta1,theta2	: Angles $(\theta_1, \theta_2)$ in radians used to select a portion of the ellipse. If theta1=0 and theta2=vpMath::rad(360) all the ellipse is displayed.
use_centered_moments	: When false, the parameters coef1, coef2, coef3 are the parameters . When true, the parameters coef1, coef2, coef3 are rather the centered moments $\mu_{20}, \mu_{11}, \mu_{02}$ expressed in pixels. In that case, we compute the parameters a, b and e from the centered moments.
color	: Drawings color.
thickness	: Drawings thickness.

All the points $(u_\theta,v_\theta)$ on the ellipse are drawn thanks to its parametric representation:

$\left(\begin{array}{c} u_\theta \\ v_\theta \end{array} \right) = \left(\begin{array}{c} u_c \\ v_c \end{array} \right) + \left(\begin{array}{cc} \cos(e) & -\sin(e) \\ \sin(e) & \cos(e) \end{array} \right) \left(\begin{array}{c} a \cos(\theta) \\ b \sin(\theta) \end{array} \right)$

with $\theta_1 \leq \theta \leq \theta_2$ .

The following example shows how to use for example this function to display the result of a tracking.

protectedvirtual

Wait for a mouse button click release and get the position of the image point were the click release occurs. The button used to click is also set. Same method as getClick(unsigned int&, unsigned int&, vpMouseButton::vpMouseButtonType &, bool).

Parameters

ip	[out] : Position of the clicked image point.
button	[in] : Button used to click.
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.
