Description:
Extensible Fractal Generator
FractalGenerator is a Qt-based program to generate fractal images (e.g. Mandelbrot set). The size of the calculated images is only limited by the computer's virtual memory. That is, images may use the full printer resolution ! . It is possible to zoom into images. Image parameters can be saved in XML files and loaded from XML files. Calculated images can be exported as PNG files. . The intention of this program is to generate graphics to be post-processed by other image tools, e.g. in order to generate nice screen backgrounds or book covers.
