XPS OM Geometri Nesneleri

Bu konu, BIR XPS OM'de geometriyle ilgili arabirimleri kullanma örneği sağlar.

Dikdörtgen geometri oluşturma

Aşağıdaki kod örneği, kapalı dikdörtgen şekli açıklayan bir geometri nesnesi oluşturur.

    HRESULT                         hr = S_OK;
    IXpsOMVisualCollection          *canvasVisuals = NULL;
    IXpsOMPath                      *pathSidebar = NULL;
    IXpsOMGeometry                  *xpsGeometry = NULL;
    IXpsOMGeometryFigure            *xpsFigure = NULL;
    IXpsOMGeometryFigureCollection  *xpsFigureCollection = NULL;
    IXpsOMSolidColorBrush           *sidebarBrush = NULL;

    XPS_POINT      startPoint;
    XPS_RECT       shape;

    // define the rectangle
    shape.x = 10.0f;
    shape.y = 10.0f;
    shape.height = 100.0f;
    shape.width = 200.0f;

    // set the start point
    startPoint.x = shape.x;
    startPoint.y = shape.y;

    // define the segment types to be straight lines
    XPS_SEGMENT_TYPE sidebarSegmentTypes[3] = {
        XPS_SEGMENT_TYPE_LINE, 
        XPS_SEGMENT_TYPE_LINE, 
        XPS_SEGMENT_TYPE_LINE
    };

    // define the points of the rectangular shape
    // other than the start point
    FLOAT sidebarSegmentData[6] = {
        shape.x,               shape.y + shape.height,
        shape.x + shape.width, shape.y + shape.height,
        shape.x + shape.width, shape.y
    };

    // set the lines to be solid (not stroked)
    BOOL sidebarSegmentStrokes[3] = {
        FALSE, FALSE, FALSE
    };

    // create the geometry figure interface
    hr = xpsFactory->CreateGeometryFigure( &startPoint, &xpsFigure );

    // close the figure so that the last segment point is
    // connected to the start point
    hr = xpsFigure->SetIsClosed( TRUE );

    // set the shape to be filled by the fill brush
    hr = xpsFigure->SetIsFilled( TRUE );

    // set the segments using the information defined above
    hr = xpsFigure->SetSegments(
        3, 
        6, 
        sidebarSegmentTypes,
        sidebarSegmentData, 
        sidebarSegmentStrokes);

    // create a geometry using the figure just created
    hr = xpsFactory->CreateGeometry(&xpsGeometry);

    // get a pointer to the figure collection
    hr = xpsGeometry->GetFigures(&xpsFigureCollection);

    // and add the figure of the rectangle to the geometry
    hr = xpsFigureCollection->Append(xpsFigure);
