Operator Set to Any Two-Operand Operation

When Operator is set to be any of the two-operand operations, the 2ndOperand properties page is displayed to set up the 2ndOperand, as shown in Figure 13-10.

2ndOperand Properties Page

• Input Gain - Apply gain to the second input image.

Range: -255.0 to 255.0

Signed Input Image and Clip Input Overflow - When the input image is unsigned, you can clip overflows when they occur. When the input image is signed, this parameter name changes to Clip Input Overflow.

Clip Input Overflow default: Enabled

• Align Regions - When enabled, the two operands' ROIs are aligned in their common part coordinates. When one of the two ROIs is relocated, the other ROI is aligned with it. Both ROIs are always maintained at the same size (the size of the ImageArith Tool) by the tool.
