Detailed Description

Display for windows using Direct3D 3rd party. Thus to enable this class Direct3D should be installed. Installation instructions are provided here https://visp.inria.fr/3rd_d3d/.

Direct3D is part of the DirectX API available under Windows operating systems.

Warning
Requires DirectX9 SDK to compile and DirectX9 DLLs to run.

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

#include <visp3/gui/vpDisplayD3D.h>
#include <visp3/io/vpImageIo.h>
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
int main()
{
#if defined(VISP_HAVE_D3D9)
vpImage<unsigned char> I; // Grey level image
// Read an image in PGM P5 format
vpImageIo::read(I, "C:/Temp/visp-images/Klimt/Klimt.pgm");
vpDisplayD3D 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 Direct 3D display");
// Set the display background with image I content
vpDisplay::display(I);
// Draw a red rectangle in the display overlay (foreground)
vpImagePoint topLeftCorner;
topLeftCorner.set_i(10);
topLeftCorner.set_j(20);
vpDisplay::displayRectangle(I, topLeftCorner, 100, 20, vpColor::red, true);
// Flush the foreground and background display
vpDisplay::flush(I);
// Wait for a click in the display window
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.

Display an ellipse from its parameters expressed in pixels.

Parameters
I: Image to consider.
center: Center $(u_c, v_c)$ of the ellipse.

  • the major and minor axis length in pixels and the eccentricity 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. In that case, we compute the parameters a, b and e from the centered moments.

◆ getKeyboardEvent() [3/8]

bool vpDisplay::getKeyboardEvent ( const vpImage< unsigned char > &  I,
char *  key,
bool  blocking = true 
)
staticinherited

Get a keyboard event.

Parameters
I[in] : The displayed image.
blocking[in] : 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.
key[out]: 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.

Below you will find an example showing how to use this method.
