What is a UPR file?

Data file used by fractal math and art programs such as Apophysis and Ultra Fractal; saved in a plain text format and contains the parameters used to generate a fractal image; often used for flame fractals; also used for sharing fractal sets with others.

More Information

Since the UPR format saves fractal parameters rather than a bitmap, it allows the fractal image to be rendered mathematically and zoomed without loss of quality. Programs that render UPR files generally can save any view within the fractal image as a raster graphic such as a .PNG, .JPG, or .BMP file.

NOTE: Apophysis is available in a source code format.
