Public Overridable Function BoundsToImageCoordinates( _
   ByVal rect As Rect _
) As Rect

Visual Basic (Usage)	Copy Code
Dim instance As ImageBox Dim rect As Rect Dim value As Rect   value = instance.BoundsToImageCoordinates(rect)

public virtual Rect BoundsToImageCoordinates( 
   Rect rect
)

public:
virtual Rect BoundsToImageCoordinates( 
   Rect rect
) 

Parameters

rect

The source rectangle in control (display) coordinates.

Return Value

For C#/VB examples, refer to PointToImageCoordinates.

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 rows and columns pixel values in the image.
