File/Export Submenu

  • as Image
    ChaosPro can save the image of a fractal (of course). ChaosPro supports JPEG files, PNG (portable network graphics) files and BMP files. PNG is more powerful than GIF, easy to implement, and very well supported. Public domain libraries containing the necessary source code exist and have been built into ChaosPro. JPEG files often are much smaller, but the image quality can be worse. JPEG is a lossy image compression format whereas PNG is lossless. It's up to you what to use.

    ChaosPro will not only save the image, it will also save the parameter entries in that file (PNG or JPEG) as comment.

    If you have calculated a 3D transformation, then a 2D image and its 3D transformation are available. If you then save the image, ChaosPro will ask you what to save.

    One note:
    Sometimes it can appear that the PNG image file cannot be loaded by other applications, specifically PaintShop Pro 5.0. This is a bug in PaintShop Pro, and not in ChaosPro: It happens whenever the "Text" chunk in the PNG file containing the parameter file entry to recreate the fractal image exceends a certain size. PaintShop Pro can handle PNG files with such text chunks only upto a certain size (which depends on how good the chunk can be compressed, i.e. what it contains...).
    To avoid that problem you need to use another image viewer or to update it.

  • as 3D Object: If you have created a 3D transformation from a 2D fractal, then you can export that fractal in two formats:
    • POVRay scene file (*.ini)
    • Wavefront Object file (*.obj)
    The Wavefront file will contain only the raw 3D object, because that format does not support much additional stuff.
    If you export a POVRay scene file, then ChaosPro will not only create the scene file, but also a heightfield and a texture map for the fractal. The scene file can be rendered without any other additional settings (at least in POVRay 3.1 and POVRay 3.5), but as new POVRay releases come out, this might not be the case with future versions of POVRay.
