BitmapMetadata.IsReadOnly 属性

定义

命名空间:

System.Windows.Media.Imaging

程序集:

PresentationCore.dll

获取一个值，该值指示与图像关联的元数据是否为只读。

public:
 property bool IsReadOnly { bool get(); };

public bool IsReadOnly { get; }

member this.IsReadOnly : bool

Public ReadOnly Property IsReadOnly As Boolean

属性值

Boolean

如果元数据为只读，则为 true；否则为 false。 默认值是 false。

示例

下面的代码示例演示如何读取对象的各种属性BitmapMetadata并将其值作为字符串发送到。MessageBox

FileStream stream4 = new FileStream("image3.tif", FileMode.Create);
BitmapMetadata myBitmapMetadata2 = new BitmapMetadata("tiff");
TiffBitmapEncoder encoder4 = new TiffBitmapEncoder();
MessageBox.Show(myBitmapMetadata2.IsFixedSize.ToString());
MessageBox.Show(myBitmapMetadata2.IsReadOnly.ToString());
MessageBox.Show(myBitmapMetadata2.Format.ToString());
MessageBox.Show(myBitmapMetadata2.Location.ToString());
encoder4.Frames = decoder2.Frames;
encoder4.Save(stream4);
stream4.Close();

Dim stream4 As New FileStream("image3.tif", FileMode.Create)
Dim myBitmapMetadata2 As New BitmapMetadata("tiff")
Dim encoder4 As New TiffBitmapEncoder()
MessageBox.Show(myBitmapMetadata2.IsFixedSize.ToString())
MessageBox.Show(myBitmapMetadata2.IsReadOnly.ToString())
MessageBox.Show(myBitmapMetadata2.Format.ToString())
MessageBox.Show(myBitmapMetadata2.Location.ToString())
encoder4.Frames = decoder2.Frames
encoder4.Save(stream4)
stream4.Close()
