Method Detail

Init

public void Init(complex pz)

Description copied from class: Transform

Set up for a sequence of values

This function will be called at the beginning of each sequence of values (e.g. at the beginning of each fractal orbit). It will be called even if only one value is being transformed (e.g. a normal transformation formula). Use this to perform any setup that is exactly the same for each value in the sequence being transformed.

Overrides:

Init in class Transform

Parameters:

pz - the value representing the sequence; for a normal transformation formula use, this will be #pixel. In some cases this may differ from the first value passed to Iterate() if the calling code applies some other transformations.

Iterate

public complex Iterate(complex pz)

Description copied from class: Transform

Transform a single point within a sequence

After a sequence has been set up with Init(), this function will be called once for each value in the sequence. Note that all values in the sequence must be processed in order (they cannot be processed out of order). If the sequence contains only one value, Init() will still be called and then Iterate() will be called just once.

Overrides:

Iterate in class Transform

Parameters:

pz - the complex value to be transformed

Returns:

the transformed value
