Detailed Description

Display for windows using GDI (available on any windows 32 platform).

GDI stands for Graphics Device Interface and is a core component of Microsoft Windows operating systems used for displaying graphics in a window.

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

#include <visp3/gui/vpDisplayGDI.h>
#include <visp3/io/vpImageIo.h>
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;

// Read an image in PGM P5 format

#else
vpImageIo::read(I, "/local/soft/ViSP/ViSP-images/Klimt/Klimt.pgm");
#endif
vpDisplayGDI 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 GDI 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

In that case, we compute the parameters a, b and e from the centered moments.

◆ getClickUp() [5/5]

bool vpDisplayWin32::getClickUp ( vpImagePoint & ip,
vpMouseButton::vpMouseButtonType & button,
bool blocking = true )
protectedinherited

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

◆ getKeyboardEvent() [8/8]

bool vpDisplayWin32::getKeyboardEvent ( std::string & key,
bool blocking )
protectedinherited

Get a keyboard event.

Parameters
[in]blocking: Blocking behavior.
  • When set to true, this method waits until a key is pressed and then returns always true.
  • When set to false, returns true only if a key is pressed, otherwise returns false.
[out]key: If possible, an ISO Latin-1 character corresponding to the keyboard key.
Returns
  • true if a key was pressed. This is always the case if blocking is set to true.
  • false if no key was pressed. This can occur if blocking is set to false.
