Detailed Description

The vpDisplayGTK allows to display image using the GTK 3rd party library. Thus to enable this class GTK should be installed. Installation instructions are provided here https://visp.inria.fr/3rd_gtk.

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

#include <visp3/core/vpConfig.h>
#include <visp3/core/vpImagePoint.h>
#include <visp3/gui/vpDisplayGTK.h>
#include <visp3/io/vpImageIo.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

Member Enumeration Documentation

◆ vpScaleType

enum vpDisplay::vpScaleType

inherited

Values that could be applied to a display to down scale the size of the display.

Enumerator
SCALE_AUTO	Auto down scaling factor computed fom the screen resolution.
SCALE_1	Display and image have the same size.
SCALE_2	Display width and height is down scaled by 2 wrt the image size.
SCALE_3	Display width and height is down scaled by 3 wrt the image size.
SCALE_4	Display width and height is down scaled by 4 wrt the image size.
SCALE_5	Display width and height is down scaled by 5 wrt the image size.
SCALE_6	Display width and height is down scaled by 6 wrt the image size.
SCALE_7	Display width and height is down scaled by 7 wrt the image size.
SCALE_8	Display width and height is down scaled by 8 wrt the image size.
SCALE_9	Display width and height is down scaled by 9 wrt the image size.
SCALE_10	Display width and height is down scaled by 10 wrt the image size.
SCALE_DEFAULT	Display and image have the same size. Similar to vpDisplay::SCALE_1.

Constructor & Destructor Documentation

◆ vpDisplayGTK() [1/6]

vpDisplayGTK::vpDisplayGTK ( )

Basic constructor.

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

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

Definition at line 237 of file vpDisplayGTK.cpp.

◆ vpDisplayGTK() [2/6]

vpDisplayGTK::vpDisplayGTK	(	int	x,
		int	y,
		const std::string &	title = `""`
	)

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

Definition at line 208 of file vpDisplayGTK.cpp.

References vpDisplay::m_title, vpDisplay::m_windowXPosition, and vpDisplay::m_windowYPosition.

◆ vpDisplayGTK() [3/6]

vpDisplayGTK::vpDisplayGTK	(	vpImage< unsigned char > &	I,
		vpScaleType	scaleType
	)

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).

scaleType

: If this parameter is set to:

vpDisplay::SCALE_AUTO, the display size is adapted to ensure the image is fully displayed in the screen;
vpDisplay::SCALE_DEFAULT or vpDisplay::SCALE_1, the display size is the same than the image size.
vpDisplay::SCALE_2, the display size is downscaled by 2 along the lines and the columns.
vpDisplay::SCALE_3, the display size is downscaled by 3 along the lines and the columns.

bool vpDisplayGTK::getClick ( bool blocking = true )

protected

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.

bool vpDisplay::getClickUp	(	const vpImage< vpRGBa > &	I,
		vpImagePoint &	ip,
		vpMouseButton::vpMouseButtonType &	button,
		bool	blocking = `true`
	)

staticinherited

Wait for a mouse button click release and get the position of the clicked image point. The button used to click is also set.

Parameters

I	[in] : The displayed image.
ip	[out] : The coordinates of the clicked image point.
button	[out] : The clicked button.
