我正在做一个项目,正在从kinect捕获帧并对其进行一些实时处理,我需要显示位图,以便将它们转换为bmapsource并传递给image.source:
Bitmap bmap = new Bitmap(640, 480, System.Drawing.Imaging.PixelFormat
.Format24bppRgb);
BitmapSource bmapSource= System.Windows.Interop.Imaging.
CreateBitmapSourceFromHBitmap(bmap.GetHbitmap(),IntPtr.Zero, Int32Rect.Empty,
BitmapSizeOptions.FromEmptyOptions());
image.source = bmapSource;
但是,当我在2分钟后处理15FPS时,出现此部分错误“ Out of memory”。
在每个过程之后是否都有清除内存的方法?还是有其他方法可以在wpf中显示bmap?
提前致谢 :)
最佳答案
尝试这个:
[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern bool DeleteObject(IntPtr hObject);
IntPtr bmp;
{
if (bmp != null)
{
DeleteObject(bmp);
}
Bitmap bmap = new Bitmap(640, 480, System.Drawing.Imaging.PixelFormat
.Format24bppRgb);
bmp = bmap.GetHbitmap();
BitmapSource bmapSource = System.Windows.Interop.Imaging.
CreateBitmapSourceFromHBitmap(bmp, IntPtr.Zero, Int32Rect.Empty,
BitmapSizeOptions.FromEmptyOptions());
bmap.Dispose();
bmap = null;
image.Source = bmapSource;
}
