CImage:Cols

The Cols method returns the number of columns in the CImage, which is defined as the length of axis 1. The Cols method still is supported but has been replaced by the more general Len method.

Syntax

nCols = CImage:Cols()

where

nCols is the length, in pixels, of image axis 1.

On failure, this method returns 0.

Example

Suppose that CImage I has dimension 1024 x 512 x 64. Then

nLen = I:Len(1)	-- returns nLen = 1024
nLen = I:Len()	-- returns nLen = 33554432
