Int数组到windows phone中的WriteableBitmap

Question

如何在Windows Phone 8中将int []像素数组转换为WriteableBitmap？之后，我想将此图像保存到MediaLibrary。

Answer 1

我在Windows Phone上知道的唯一方法是使用WriteableBitmapEx库。除了WriteableBitmap之外，它还实现了“具有各种重载的SetPixel方法”：

可以从Visual Studio 2012中简单地安装库：

Answer 2

您可以使用int []的copyTo成员函数将int []复制到WriteableBitmap。

int[] ARGBPx = new int[(int)captureDevice.PreviewResolution.Width * (int)captureDevice.PreviewResolution.Height];            
WriteableBitmap writeableBitmap_preview;        

ARGBPx.CopyTo(writeableBitmap_preview.Pixels, 0);         
writeableBitmap_preview.Invalidate();
