如何获得矿山输入视频的灰度输出? [英] how to get output as a grayscale for mine input video?

问题描述

private void Filter_Invert(object sender, System.EventArgs e)
		{
			if(BitmapFilter.Invert(m_Bitmap))
				this.Invalidate();
		}

		private void Filter_GrayScale(object sender, System.EventArgs e)
		{
			if(BitmapFilter.GrayScale(m_Bitmap))
				this.Invalidate();
		}
