type
Flag that indicates the function to be applied.
factor
Value that is used as an amplitude factor when squaring, taking the logarithm of or taking the square root of the color values and as a frequency factor when taking the sine or cosine of the color values. The factor value is divided internally by different amounts, according to the type of the function being used. These amounts are as follows:
if the type parameter is set to: | then the factor parameter will be divided by: |
---|---|
Square | 10000 internally |
Logarithm | 10 internally |
Square Root | 10 internally |
Sine | 100 internally |
Cosine | 100 internally |
Only positive values are accepted.
Run the MathematicalFunctionCommand on an image with square function selected and factor = 50.
