Using the Operators function

1. Click Grayscale»Operators or click Operators in the Grayscale tab of the Processing Functions palette.
2. Select one of the functions from the Operators list.
3. Select either the Constant or Image option. The Constant option uses a constant and the current image in the operation. The Image option uses the current image and an image stored in an image buffer.
4. Enter the constant or select the image buffer that contains the image you are combining with the source image.
5. Click OK to perform the operation.

Note   You must already have an image stored in an image buffer before you can perform an operation using the current image and another image. The buffered image must have the same size and type as the source image.
