Detailed Description

Class to define colors available for display functionnalities.

You may use predefined colors (black, white, red, green, blue, cyan and orange) or specify your own color by settings its R,G,B values.

An identifier vpColorIdentifier is associated to each color. This identifier is useful to determine if a color is predefined or specified by it R,G,B values. In that last case, the identifier is always set to vpColor::id_unknown.

The example below shows how to display geometric features in a display overlay using predefined colors (here the blue color to draw a circle) and a specific brown color (used to draw a rectangle).

#include <visp3/core/vpConfig.h>
#include <visp3/gui/vpDisplayD3D.h>
#include <visp3/gui/vpDisplayGDI.h>
#include <visp3/gui/vpDisplayGTK.h>
#include <visp3/gui/vpDisplayOpenCV.h>
#include <visp3/gui/vpDisplayX.h>
int main()
{
vpImage<unsigned char> I(240, 320); // Create a black grey level image
// Depending on the detected third party libraries, we instantiate here the
// first video device which is available
#if defined(VISP_HAVE_X11)
d = new vpDisplayX;
#elif defined(VISP_HAVE_GTK)
d = new vpDisplayGTK;
#elif defined(VISP_HAVE_GDI)
d = new vpDisplayGDI;
#elif defined(VISP_HAVE_D3D9)
d = new vpDisplayD3D;
#elif defined(VISP_HAVE_OPENCV)
d = new vpDisplayOpenCV;
#endif
// Initialize the display with the image I. Display and image are
// now link together.
#ifdef VISP_HAVE_DISPLAY
d->init(I);
#endif
// Set the display background with image I content
// Draw a filled circle with the predefined blue color
vpDisplay::displayCircle(I, 100, 200, 30, vpColor::blue, true);
// Creation of a new brown color with its RGB values
vpColor color(128, 100, 50);
// Draw a brown rectangle in the display overlay (foreground)
vpDisplay::displayRectangle(I, 10, 10, 100, 20, color, true);
// Flush the foreground and background display
delete d;
}
