示例1: CopyStreamToSurface
internal static void CopyStreamToSurface(SharpDX.DataBox dbox, Surface dst, Rectangle rect)
{
IntPtr textureBuffer = dbox.DataPointer;
IntPtr dstPointer = dst.GetPointPointer(rect.Left, rect.Top);
if (rect.Width == dst.Width)
{
CopyMemory(dstPointer, textureBuffer, rect.Width * rect.Height * COLOR_SIZE);
}
else
{
int length = rect.Width * COLOR_SIZE;
int dstStride = dst.Stride;
int rectBottom = rect.Bottom;
for (int y = rect.Top; y < rectBottom; y++)
{
CopyMemory(dstPointer, textureBuffer, length);
textureBuffer = IntPtr.Add(textureBuffer, length);
dstPointer = IntPtr.Add(dstPointer, dstStride);
}
}
}示例2: CopyRois
private unsafe void CopyRois(Rectangle[] rois, Surface dest, Surface source)
{
int COLOR_SIZE = Marshal.SizeOf(typeof(ColorBgra));
foreach (Rectangle copyRect in rois)
{
int length = copyRect.Width * COLOR_SIZE;
for (int y = copyRect.Top; y < copyRect.Bottom; y++)
{
CopyMemory(dest.GetPointPointer(copyRect.Left, y), source.GetPointPointer(copyRect.Left, y), length);
}
