The MaintainAspectRatio Property supports WPF/Silverlight.
The MaintainAspectRatio Property is available in LEADTOOLS Document and Medical Imaging toolkits.
Gets or sets a value that indicates whether to preserve the aspect ratio when moving a corner control point for all AnnEditDesigner derived classes. Supported in Silverlight, Windows Phone 7
Syntax
| Visual Basic (Declaration) | |
|---|---|
Public Property MaintainAspectRatio As Boolean | |
| Visual Basic (Usage) |  Copy Code |
|---|---|
Dim instance As AnnAutomationManager Dim value As Boolean instance.MaintainAspectRatio = value value = instance.MaintainAspectRatio | |
| C# | |
|---|---|
public bool MaintainAspectRatio {get; set;} | |
Property Value
true to maintain the aspect ratio; otherwise, false.Example
This example makes it so that when moving the corner control points of a rectangular annotation object, the aspect ratio is not preserved.
| Visual Basic | Copy Code |
|---|---|
Private Sub AnnAutomationManager_MaintainAspectRatio(ByVal manager As AnnAutomationManager) manager.MaintainAspectRatio = False End Sub | |
| C# | Copy Code |
|---|---|
private void AnnAutomationManager_MaintainAspectRatio(AnnAutomationManager manager) { manager.MaintainAspectRatio = false; } | |
| SilverlightCSharp | Copy Code |
|---|---|
private void AnnAutomationManager_MaintainAspectRatio(AnnAutomationManager manager) { manager.MaintainAspectRatio = false; } | |
| SilverlightVB | Copy Code |
|---|---|
Private Sub AnnAutomationManager_MaintainAspectRatio(ByVal manager As AnnAutomationManager) manager.MaintainAspectRatio = False End Sub | |
Remarks
When selecting an AnnRectangleObject, any annotation object that derives from AnnRectangleObject, or an AnnGroupObject, eight control points appear. If MaintainAspectRatio is true (default), dragging one of the four corner control points will change the size of the annotation object while maintaining its aspect ratio. If false, the aspect ratio is not preserved.
