關於採圖,上面用的是官方的SDK方式,因為我採集的圖片像素是8K*8K,原圖BMP格式有256MB,壓縮成30%質量的JPG也還有2.3MB左右。
還有一種方式是用Bitmap來獲取圖片地址,但是需要註意的一點。
IntPtr addr; int Height = m_Buffers.Height; int Width = m_Buffers.Width; m_Buffers.GetAddress(out addr); bitmap = new Bitmap(Width, Height, Width * 4, System.Drawing.Imaging.PixelFormat.Format32bppRgb, addr);
這裡的寬度是*4,原因是我的BMP原圖圖像位深度是32位的。所以保存用Bitmap的方式需要先確定原圖的位深度,否則保存圖片會出現重影。
