Access rectangle object placed in excel using aspose

Dear Aspose Team,

My goal is to find out if a cell has any object placed on it or not. I have a placed a rectangle object from excel starting from cells (say for example from 3 to 11).

Now I want to find out if the cell 33 has a rectangle object placed on it or not?.

Please find attached the sheet for reference.I have placed a rectangle object from cell 3 to 11. I want to find out using aspose if the cell 3 , cell 4 has any object on it.

Thanks

Siva
