Executing an Arithmetic Operation:

  • click on Image and Arithmetic Operation... on the main menu;
  • click on on the button Operation and choose the desired operation. Depending on what you choose you will have to inform the input bands (A and/or B);
  • click on A or B and then click on an Infolayer from the list. Observe that the ILs list only presents the selected category on the Control Panel;
  • click on the Gain text box and type the value. Do the same at the Offset text box;
  • click on the Output C: text box and type an IL name for the operation outcome;
  • click on Apply to execute the operations between the bands. Observe that the new generated image will be presented in the Control Panel. There will be a suffix added to the name which refers to the chosen operation.

NOTE: Suppose the output Image name is "Ima_output" and the chosen operation is the second on the list (C=Gain*(A-B)+Offset), the created image will have the name "Ima_output-(OP2)".
