CImage:Exp
The Exp method raises the base e to powers defined by the pixel values.
bResult = CImage:Exp() |
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.
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() |
