Translates a point (x,y) from this RasterImage view perspective to the specified view perspective.
public LeadPoint PointFromImage(
RasterViewPerspective viewPerspective,
LeadPoint pt
)
Public Function PointFromImage( _
ByVal viewPerspective As RasterViewPerspective, _
ByVal pt As LeadPoint _
) As LeadPoint
- (LeadPoint)pointFromImage:(LTRasterViewPerspective)viewPerspective

public LeadPoint pointFromImage(
RasterViewPerspective viewPerspective,
LeadPoint pt
)
public:
LeadPoint PointFromImage(
RasterViewPerspective viewPerspective,
LeadPoint pt
)
viewPerspective
Destination view perspective to which the point should be translated.
pt
The point to translate.
The translated point.
For more information, refer to Accounting for View Perspective.
For more information, refer to Changing Image Coordinates.
This example finds out where the origin of the image should be. Then it converts a known point to bitmap coordinates.
