Release 4.0

Predefined Parameters : Escapetime

Fractal type Escapetime offers several predefined parameters, partially depending on the formula type. These parameters provide a way to access some seettings outside a formula context, for example the rotation angle or the screen resolution.

Please note: Different fractal types (currently Escapetime and Quaternion) offer different predefined parameters.

The following parameters exist:

The table lists the datatype of the predefined parameter and one of the following abbreviations:

• - - -: not available
• r/o means: read-only
• r/w means: read-write
• w/o means: write-only
