Parameter files

Fractals can be saved as parameter sets as well as in 

fractal files

. Parameter sets are much smaller 

than fractal files because they do not contain the calculated pixels. That means that the fractal has to 

be recalculated when a parameter set is opened. Parameter sets are ideal for sharing fractals with 

other users on the Internet.

Parameter sets are stored in parameter files. A parameter file (*.upr) can contain any number of 

parameter sets. This makes it easy to store and organize collections of parameter sets. Parameter 

files are stored as plain text and can be opened in text editors such as Notepad or the built in 

formula editor

.

To save a parameter set, click Save Parameters on the File menu. The Save Parameters 

browser will open. You can save the parameter set in an existing parameter file or in a new 

  file. Type the name of the file and the title of the parameter set and click Save.

To open a previously saved parameter set, click Browse on the File menu. This opens a 

modeless browser. Select the parameter file that contains the parameter set that you want 

  to open, and then double click the parameter set inside the file.

You use browsers to organize and manage your parameter sets and parameter files, as well as other 

files that contain multiple entries, such as formula files. See 

Browsers

.

Notes

G     

By checking the Save Formulas checkbox when saving a parameter set, the formulas used 

by the fractal are embedded in the parameter file. When opening the parameter set, they will 

be installed if they are not already present in the formulas folder. Check this option when 

you are going to send the parameter file to another user (but not on the 

mailing list

).

G     

Parameter sets larger than 2 KB are saved in a compressed format. To save them without 

compression, open the 

Options dialog

 and uncheck "Compress parameter sets larger than 2 

KB" in the Fractal tab. This is necessary if you want to edit the parameter files manually.

G     

Ultra Fractal can also import most Fractint parameter sets in PAR files (*.par). They can be 

opened just like other parameter files.
