Use this function to multiply each pixel in an image to a constant value. The following formula is used for calculating the intensity of a target pixel:



If a pixel's result falls outside of the image's intensity scale, it will be clipped or wrapped around the highest /lowest permitted value, depending on the Mode selected.

If you choose this command, the following options will become available:

Input

Factor

Lets you enter the constant value that will be multiplied to each pixel of the image.

Mode

Lets you select the mode for the operation.

Click Wrap to have the output pixel values which fall outside of the image's intensity range to wrap around the highest permitted value or zero level.

Click Clip to have pixel values the output pixel values which fall outside of the image's intensity range clipped to the highest permitted value or zero level.
