Translates a rectangle from this RasterImage view perspective to the specified view perspective.
public LeadRect RectangleFromImage(
RasterViewPerspective viewPerspective,
LeadRect rc
)
Public Function RectangleFromImage( _
ByVal viewPerspective As RasterViewPerspective, _
ByVal rc As LeadRect _
) As LeadRect
- (LeadRect)rectangleFromImage:(LTRasterViewPerspective)viewPerspective

public LeadRect rectangleFromImage(
RasterViewPerspective viewPerspective,
LeadRect rc
)
public:
LeadRect RectangleFromImage(
RasterViewPerspective viewPerspective,
LeadRect rc
)
viewPerspective
Destination view perspective to which the rectangle should be translated.
rc
The rectangle to translate.
The translated rectangle.
For more information, refer to Accounting for View Perspective.
For more information, refer to Changing Image Coordinates.
This example finds out where the selected rectangle of the image would be in a TopLeft ViewPerspective.
