RasterRegion to fit inside a specified
LeadRect.
Supported in Silverlight, Windows Phone 7
Syntax
Visual Basic (Declaration) | |

Public Sub Clip( _
ByVal rect As LeadRect _
) |
Parameters
- rect
- A LeadRect that defines the clipping boundaries.
Example
This example will create a large elliptical region in an image and fill it with yellow. It will then clip this region by 10 pixels from each side and fill the new region with red.
