rect
The source rectangle in image coordinates.
rect
The source rectangle in image coordinates.
Converts a rectangle from image to control (display) coordinates. Supported in Silverlight, Windows Phone 7

Syntax

Visual Basic (Declaration) 
Public Overridable Function BoundsFromImageCoordinates( _
   ByVal rect As Rect _
) As Rect
Visual Basic (Usage)Copy Code
Dim instance As ImageViewer
Dim rect As Rect
Dim value As Rect
 
value = instance.BoundsFromImageCoordinates(rect)
C# 
public virtual Rect BoundsFromImageCoordinates( 
   Rect rect
)
C++/CLI 
public:
virtual Rect BoundsFromImageCoordinates( 
   Rect rect
) 

Parameters

rect
The source rectangle in image coordinates.

Return Value

A System.Windows.Rect that contains the converted values in control (display) coordinates.

Example

For C#/VB examples, refer to PointToImageCoordinates.

Remarks

The viewer control contain many properties that control how the image will be displayed on the surface of the control. At any time, you might require to convert a point or a rectangle from control (where it is on the surface of the control) to image (the pixel x and y value in the image data) and vice versa.

Use PointToImageCoordinates to convert a point from control to image coordinates, use PointFromImageCoordinates to convert a point from image to control coordinates. Use BoundsToImageCoordinates to convert a rectangle value from control to image coordinates and BoundsFromImageCoordinates to convert a rectangle value from image to control coordinates.

Note that when using the RasterImageBox and RasterImageViewer controls to display a LEADTOOLS Leadtools.RasterImage object, the image coordinates are assumed to be in top-left view perspective. If the image contains a RasterImage.ViewPerspective value other than RasterViewPerspective.TopLeft you must call RasterImage.PointToImage or RasterImage.RectangleToImage to further convert the values to actual row and column pixel values in the image.

Requirements

Target Platforms: Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family
