我在我的一个页面上展示了一张我拍的照片。
我以人像模式拍摄照片,它工作正常。
当我在下一个视图中显示照片时,它会将照片视为在风景中拍摄的。
所以我需要将图片/图像旋转-90 来纠正这个问题。
这是我的 .XAML 的相关代码:
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanelx" Grid.Row="1" Margin="0,0,0,0">
</Grid>
这是我加载照片并将其放入 ContentPanel 的方法:
void loadImage()
{
// The image will be read from isolated storage into the following byte array
byte[] data;
// Read the entire image in one go into a byte array
using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
{
// Open the file - error handling omitted for brevity
// Note: If the image does not exist in isolated storage the following exception will be generated:
// System.IO.IsolatedStorage.IsolatedStorageException was unhandled
// Message=Operation not permitted on IsolatedStorageFileStream
using (IsolatedStorageFileStream isfs = isf.OpenFile("0.jpg", FileMode.Open, FileAccess.Read))
{
// Allocate an array large enough for the entire file
data = new byte[isfs.Length];
// Read the entire file and then close it
isfs.Read(data, 0, data.Length);
isfs.Close();
}
}
// Create memory stream and bitmap
MemoryStream ms = new MemoryStream(data);
BitmapImage bi = new BitmapImage();
// Set bitmap source to memory stream
bi.SetSource(ms);
// Create an image UI element – Note: this could be declared in the XAML instead
Image image = new Image();
// Set size of image to bitmap size for this demonstration
image.Height = bi.PixelHeight;
image.Width = bi.PixelWidth;
// Assign the bitmap image to the image’s source
image.Source = bi;
// Add the image to the grid in order to display the bit map
ContentPanelx.Children.Add(image);
}
}
加载后,我正在考虑对图像进行简单的旋转。我可以在 iOS 中做到这一点,但我的 C# 技能比坏还差。
有人可以就此提出建议吗?
