This is done to facilitate proper scaling of the data when displayed. If set to Check , the operator will check for division by zero as described above. An image of any data type can be given as input. The proper data conversions are performed to ensure output is of an appropriate type for the range of values the exponentiation produces. The smallest data type that is produced is ilChar .
Exponentiation is computed for any base specified.
This is done to facilitate proper scaling of the data when displayed. Arithmetic ilInvImg computes the pixelwise one's complement of any valid image. An image of any data type may be given as input, except ilFloat and Double . Example of an inversion. Arithmetic ilLogImg performs a pixelwise logarithm of any valid image.
