我的申请将HLSL的沙分效应适用于使用矫正器的媒体。 我如何实时记录和拯救经过修改的录像?
What is the use of default keyword in C#? Is it introduced in C# 3.0 ?

我一直在使用RenderTargetBitmap标语,使图像序列像这样:
阁下:
myStoryboard.CurrentTimeInvalidated += new EventHandler(onCurrentTimeInvalidated );
如果我的历史板是推测的故事板,那么你有以下方法:
void onCurrentTimeInvalidated (object sender, EventArgs e)
{
prefix = "";
if (counter < 10)
{
prefix = "000";
}
else if (counter < 100)
{
prefix = "00";
}
else if (counter < 1000)
{
prefix = "0";
}
Size size = new Size(MainCanvas.ActualWidth, MainCanvas.ActualHeight);
MainCanvas.Measure(size);
MainCanvas.Arrange(new Rect(size));
RenderTargetBitmap bmp = new RenderTargetBitmap(imgWidth, imgHeight, 96d, 96d, PixelFormats.Default);
bmp.Render(MainCanvas);
JpegBitmapEncoder encoder = new JpegBitmapEncoder();
encoder.QualityLevel = 90;
encoder.Frames.Add(BitmapFrame.Create(bmp));
string file = basePath + prefix + counter.ToString() + "_testpic.jpg";
using (Stream stm = File.Create(file))
{
encoder.Save(stm);
}
counter++;
}
我不相信这将与媒体合作,但可能值得尝试。 要做到这一点,就媒体要素开展工作,尽管你需要把媒体内容从媒体时代推向前进,并从目前的时代印证活动中采用实时方法。
