drawBufferSpan()

void QDirectFBPaintEngine::drawBufferSpan ( const uint *  buffer, int  size, int  x, int  y, int  length, uint  alpha  )

virtual

Draws the given buffer.

The default implementation does nothing; reimplement this function to draw a buffer that contains more than one color. Note that this function must be reimplemented if the framebuffer is not memory-mapped.

The size parameter specifies the total size of the given buffer, while the length parameter specifies the number of pixels to draw. The buffer's position is given by (x, y). The provided alpha value is added to each pixel in the buffer when drawing.

    - If you do not have support for preallocated surfaces and do not use an
    image cache we always fall back to raster engine.

    - If it's rotated/sheared/mirrored (negative scale) or we can't
    clip it we fall back to raster engine.

    - If we don't cache the image, but we do have support for
    preallocated surfaces we fall back to the raster engine if the
    image is in a format DirectFB can't handle.

    - If we do cache the image but don't have support for preallocated
    images and the cost of caching the image (bytes used) is higher
    than the max image cache size we fall back to raster engine.

drawPoints() [2/2]

void QDirectFBPaintEngine::drawPoints ( const QPoint *  points, int  pointCount  )

virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Draws the first pointCount points in the buffer points.

The default implementation converts the first pointCount QPoints in points to QPointFs and calls the floating point version of drawPoints.
