Parameters - pixel

Name: pixel

Type: complex

Read/Write: Read+Write

Context: Transformation, Iteration, Coloring

Description:

This variable contains the complex number which corresponds to the pixel which is currently examined.

A transformation normally reads this value and transforms it in some way, i.e. changes its value.

An iteration formula normally only reads this value and calculates the next z value depending on the pixel. But an iteration formula may also change the pixel.

Note:

For Escapetime fractals, the datatype of the predefined variable pixel is complex. If you use Quaternions, then the datatype of the predefined variable is quaternion. See pixel for Quaternions.
