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>
int main()
{
#if defined(VISP_HAVE_GDI)
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
// Initialize the display with the image I. Display and image are
// now link together.
d.init(I);
// Specify the window location
// Set the display window title
vpDisplay::setTitle(I, "My GDI display");
// Set the display background with image I content
// 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
// 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;
}
// 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;
#endif

Parameters
I: Image to consider.

  • the major and minor axis lenght in pixels and the excentricity of the ellipse in radians: $a, b, e$.
use_normalized_centered_moments: When false, the parameters coef1, coef2, coef3 are the parameters $a, b, e$. When true, the parameters coef1, coef2, coef3 are rather the normalized centered moments $n_{20}, n_{11}, n_{02}$ expressed in pixels.
