Define Render Job Window

^{Fig.: Render job window} The render job window lets you define new render jobs which then are added to the render jobs windows.

At the top of the window you can choose betwen File and Project:

File: Right below you can enter a parameter file (*.par, or *.upr). All fractals contained in it will then be displayed in the list box at the right side of the window.
Project: Right below you can choose a project (i.e. a *.par or *.upr file which has already been loaded and perhaps modified).

Destination

A sub directory named like the project (or file) will be created below the destination directory and your final images will be saved into that sub directory.

File Format

You can choose between two file formats:

PNG - Lossless compression, best quality, but large images.
JPG - Lossy compression method, quality can be adjusted (options button right beneath), the resulting images normally are smaller.

Fractals

In this list box you can see all fractals which are stored in the current project or the selected file. You can select several of them in order to add a render job for each selected fractal.

Size

Here you can specify the width and height of the resulting images.

If you select Keep Aspect Ratio then the aspect ratio (i.e. the proportion of width to height) will be preserved. So if a fractal in a project has a default size of 800x400 and you select a desired size of 6400x4800 and select "keep aspect ratio", then ChaosPro will create an image which is twice as wide than height, but not larger than 6400x4800, thus ChaosPro will render it at 6400x3200.

The static text fields below indicate how much memory is currently available on your harddrives.

Anti Aliasing

Here you can specify the anti aliasing settings. You can either choose a preset (Default, Deep, Off) or manually choose your settings (Custom). Anti aliasing in ChaosPro works as follows: ChaosPro tries to find out the color of a pixel. So it examines the neighboring pixels (either 2x2 or 3x3, subdivision) and calculates how much they differ (0 = all pixels have the same color, 1=all pixels have completely other colors, 0.1=all pixels are quite similar, etc.). If that value is bigger than the threshold then ChaosPro divides the pixel in question into 2x2 or 3x3 smaller pixels, calculates their colors, compares to threshold, etc.
This method ensures that the time consuming task of calculating a pixel color is applied only to the portions of a fractal where the pixel colors change rapidly, saving much time.

Threshold : If adjacent pixels differ more than this threshold value then a sub division takes place and more pixels are being calculated in order to determine the anti aliased pixel color. It must be in the range 0 to 1.
Depth: Specifies how many sub divisions may take place.
Subdivision: Specifies whether to do a 2x2 or a 3x3 sub division if necessary.
