問題: 我以90度逆時針旋轉1次風景圖像1次。重建圖像後,它看起來並沒有看到它在逆時針位置旋轉了1次。它提供順時針90度的圖像。如何在逆時針旋轉後重建圖像
我用下面的代碼:
var encoder = await BitmapEncoder.CreateAsync(BitmapEncoder.PngEncoderId, fileStream); encoder.SetPixelData( BitmapPixelFormat.Bgra8, BitmapAlphaMode.Ignore, (uint)renderTargetBitmap.PixelWidth, (uint)renderTargetBitmap.PixelHeight, DisplayInformation.GetForCurrentView().LogicalDpi, DisplayInformation.GetForCurrentView().LogicalDpi, pixelBuffer.ToArray()); encoder.BitmapTransform.Rotation = BitmapRotation.Clockwise90Degrees; await encoder.FlushAsync(); There is no AntiClockwise90Degrees in BitmapRotation
如何解決這個問題呢?
