'Применение
Dim instance As Ink

public function Save(
    p : PersistenceFormat
) : byte[]

Параметры

p
Тип: Microsoft.Ink.PersistenceFormat
A member of the PersistenceFormat enumeration that indicates the format of the persisted ink.

Возвращаемое значение

Тип: array<System.Byte[]
The Byte array that contains the persisted ink.

Заметки

Attempting to save an empty Ink object in Gif format generates an error.

Примечание.
When calling the Save method with the p parameter set to Base64InkSerializedFormat, the return value is a null-terminated byte array. To write the saved ink to an XML file, first remove the last byte from the array before converting the array to an 8-bit Unicode Transformation Format (UTF-8)-encoded string.

Примеры

In this example, the Ink object of an InkOverlay object is saved to a file in Gif format.

Try
    ' FILE_NAME is a class level const
    Using FS As FileStream = New FileStream(FILE_NAME, FileMode.Create)
        Dim isf As Byte() = mInkOverlay.Ink.Save(PersistenceFormat.Gif)
        FS.Write(isf, 0, isf.Length)
    End Using

Catch
    ' handle or rethrow
End Try

try
{
    // FILE_NAME is a class level const
    using (FileStream FS = new FileStream(FILE_NAME, FileMode.Create))
    {
        byte[] isf = mInkOverlay.Ink.Save(PersistenceFormat.Gif);
        FS.Write(isf, 0, isf.Length);
    }
}
catch
{
    // handle or rethrow
}
