Value Arithmetic

The Value Arithmetic command performs arithmetic operations between an image and a numeric value, or "operand".

  • The Value Arithmetic command opens from the Image Window > Process > Math menu and button on the Main Toolbar. The "immediate" form, shown first, opens when an image or image set is displayed in the top-most window. The general form can be used to select source images from folders, windows, or by matching templates.

Constant Value Arithmetic Properties

Profile [|>]

Selects the parameter profile for this command and allows you to save or work with existing presets.

[Select]

Opens the Select Source Images dialog to choose images from an image window, folder, files, name template, or a Mira File List.

Operation

Select the operation to perform from the following options:

Add

Adds the operand value to the image pixel values.

Subtract

Subtracts the operand value from the image pixels.

Subtract From

Subtracts the image pixels from the operand value.

Multiply

Multiples the image pixels by the operand value.

Divide

Divides the image pixels by the operand value.

Divide Into

Divides the image pixel values into the operand value.

Blend

Blends (interpolates) the images pixel values with the operand value.

Remainder

Calculates the remainder of dividing the image pixel values by the operand value.

Value

Specifies the value to apply to the source images using the selectedOperation.

Error replacement value

Specifies the value to replace in the pixel when an illegal operation is performed.
