CImage:Exp

CImage:Exp

The Exp method raises the base e to powers defined by the pixel values.

Syntax

bResult = CImage:Exp()

On success, this method returns true
On failure, this method returns false.

Remarks

The Exp operation can overflow quickly if the pixel values are large numbers. For example, if a pixel has value 100, then e^100 is a very large number.

Example

The following script fragment loads an image from the file sPath, computes the exponential of all the pixels, and saves the result back to the file:

I = CImage:new()	-- create a new CImage
I:Open(sPath)	-- load the image from a file named sPath
I:Exp()	-- perform the operation
I:Save()
