I did a subtraction of a data frame in ArcGIS using the following steps. I prepared a layout in ArcGIS. There is a lot of empty space at the top of layout page. So I want to remove this space. I used a graphic operation to remove it.
- Created a graphic rectangle that the same size as the Data Frame
- Created another rectangle covering empty space
- Selected rectangle 2, then rectangle 1, and chose--> Graphic Opperations --> Subtract.
- In the last step, I wanted to clip the subtracted image by "Outline of Selected graphic". But 'Outline of selected graphic' is not activated. I can't click it. I'm wondered why this is not activated?
Thanks a lot.
