CImage:Recip

The Recip method computes the reciprocal of the pixel values.

Syntax

bResult = CImage:Recip()

bullet.gif    On success, this method returns true

bullet.gif    On failure, this method returns false.

Remarks

Usually, the image should have real type pixels before using this method. The pixel type can be tested and changed using IsReal and SetPixelType . See Pixel Types for more information.

Example

The following script loads an image from the file sPath, computes the reciprocal, and saves the result back to the file:

I = new_image()

-- create a new CImage

I:Open(sPath)

-- load the image from a file named sPath

I:Recip()

-- perform the operation

I:Save()
