示例1: Apply
public void Apply(FastBitmap surface, Rectangle[] roi, int startIndex, int length)
{
Rectangle regionBounds = Utility.GetRegionBounds (roi, startIndex, length);
if (regionBounds != Rectangle.Intersect (surface.GetBounds (), regionBounds))
throw new ArgumentOutOfRangeException ("roi", "Region is out of bounds");
unsafe {
for (int x = startIndex; x < startIndex + length; ++x)
ApplyRectangle (surface, roi[x]);
}
}示例2: ApplyBase
/// <summary>
/// Provides a default implementation for performing dst = F(dst, src) or F(src) over some rectangle
/// of interest. May be slightly faster than calling the other multi-parameter Apply method, as less
/// variables are used in the implementation, thus inducing less register pressure.
/// </summary>
/// <param name="dst">The Surface to write pixels to, and from which pixels are read and used as the lhs parameter for calling the method <b>PixelData Apply(PixelData, PixelData)</b>.</param>
/// <param name="dstOffset">The pixel offset that defines the upper-left of the rectangle-of-interest for the dst Surface.</param>
/// <param name="src">The Surface to read pixels from for the rhs parameter given to the method <b>PixelData Apply(PixelData, PixelData)</b>b>.</param></param>
/// <param name="srcOffset">The pixel offset that defines the upper-left of the rectangle-of-interest for the src Surface.</param>
