示例1: TryGetCaptured
public unsafe bool TryGetCaptured(IDeviceContext context, IntRectangle clientRectangle, FrameType frameType, int colorDiffThreshold, int mostDetailedMip, out GpuRawFrame capturedFrame)
{
stopwatch.Restart();
var result = texturePool.Extract(clientRectangle.Width, clientRectangle.Height);
var resultTexture = result.Item;
d3dDevice.GetFrontBufferData(0, d3dSurface1);
var sdxRectangle = new Rectangle(clientRectangle.X, clientRectangle.Y, clientRectangle.X + clientRectangle.Width, clientRectangle.Y + clientRectangle.Height);
var lockedRectangle = d3dSurface1.LockRectangle(sdxRectangle, LockFlags.ReadOnly);
var mappedSubresource = context.Map(resultTexture, 0, MapType.WriteDiscard, MapFlags.None);
{
int commonRowPitch = Math.Min(mappedSubresource.RowPitch, lockedRectangle.Pitch);
Parallel.For(0, clientRectangle.Height, i =>
Memory.CopyBulk(
(byte*)mappedSubresource.Data + i * mappedSubresource.RowPitch,
