To Modify a Raster Clipping Polygon
Select the Modify Clip tool ( split button).
- If more than one raster image is attached, identify the required image.
Identify the polygon to modify, at the point at which you want to perform the modification.
That is, at a vertex if you want to move the vertex, or at a point on a side if you want to move the side.
- Move the pointer to modify the clipping polygon as required.
Enter a data point to complete the modification.
The image updates to show the new boundaries of the clipping polygon.
- (Optional) Repeat steps 3–5 for other modifications.
