mul

mul

The mul function multiples the pixels of a CImage object or 1-dimensional array by a value.

Whereas this function operates on a pure (indexed) array, the slightly slower muln function operates on a general table that may be a multi-dimensional array or contain a mixture of numbers, strings, named keys, and sub-tables.

Syntax

result = mul( object, value )

where object is a 1-dimensional array, CImage object, or simple number.

value is a number.

result is returned as an array, CImage object, or number, depending on the type of value.

Examples

The following script multiplies the members of a table by 3200.5.

t = mul( tbl, 3200.5 )

-- multiply the object by the value

The next script multiplies all pixels of a CImage by 3200.5.

V = AttachView( "CImageView" )	-- attach the topmost image window
Assert( V and V:Count() > 0 )	-- make sure an image window is on top
mul( V:GetImage(), 3200.5 )	-- multply the CImage by the value
