IWMPMedia::imageSourceHeight property
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The imageSourceHeight property gets the height of the current media item in pixels.
This property is read-only.
Syntax
public System.Int32 imageSourceHeight {get;}
Public ReadOnly Property imageSourceHeight As System.Int32
Property value
A System.Int32 that is the height of the media item.
Remarks
If the media item is not the current one, this property returns zero.
Before using this property, you must have read access to the library. For more information, see Library Access.
Examples
The following example uses imageSourceHeight to display the image size, in pixels, of the current media item in a text box. The AxWMPLib.AxWindowsMediaPlayer object is represented by the variable named player.
// Create an event handler for the OpenStateChange event.
private void player_OpenStateChange(object sender, AxWMPLib._WMPOCXEvents_OpenStateChangeEvent e)
{
// Test whether the current media item is open.
if (e.newState == (int)WMPLib.WMPOpenState.wmposMediaOpen)
{
// Store the height and width of the new media item.
int height = player.currentMedia.imageSourceHeight;
int width = player.currentMedia.imageSourceWidth;
// Clear all the information in the text box.
videoSize.Clear();
// Test whether an image is visible.
if (height != 0 && width != 0)
{
// Display the image size information.
videoSize.Text = (width.ToString() + " x " + height.ToString());
}
}
}
' Create an event handler for the OpenStateChange event.
Public Sub player_OpenStateChange(ByVal sender As Object, ByVal e As AxWMPLib._WMPOCXEvents_OpenStateChangeEvent) Handles player.OpenStateChange
' Test whether the current media item is open.
If (e.newState = WMPLib.WMPOpenState.wmposMediaOpen) Then
' Store the height and width of the new media item.
Dim Height As Integer = player.currentMedia.imageSourceHeight
Dim Width As Integer = player.currentMedia.imageSourceWidth
' Clear all the information in the text box.
videoSize.Clear()
' Test whether an image is visible.
If (Height <> 0 And Width <> 0) Then
' Display the image size information.
videoSize.Text = (Width.ToString() + " x " + Height.ToString())
End If
End If
End Sub
