Preview Window OverviewThe Fractal Science Kit fractal generator Preview Window is used to preview fractals. There is a single Preview Window for the entire application. There are 2 ways to display the Preview Window. The first way is to check the Preview Julia item on the Tools menu of the Fractal Window (or press the Preview Julia toolbar button) and then click on the fractal image to set the Julia Constant and generate a Julia fractal preview. The preview is based on the properties that were in effect when the Mandelbrot fractal was generated. That is, any changes to the properties pages since the Mandelbrot fractal was generated have no affect on the resulting Julia fractal. As long as the Preview Julia item is checked, additional clicks on the fractal image will update the Preview Window with the Julia fractal based on the new Julia Constant. The Preview Julia menu item and toolbar button are disabled on Julia fractals, Orbital fractals, and L-System fractals. The second way to display the Preview Window is to click the Preview Fractal toolbar button on the Fractal Window or the Properties Window to preview the fractal resulting from changes you have made on the Properties Pages. If the Zoom In or Zoom Out state is active on the associated Fractal Window, the zoom is applied to the preview as well.
The Preview Window is a small version of the target fractal and is usually faster to generate than a full-sized version. The Mandelbrot fractal iteration is greatly affected by the size of the image so the Preview Window is much faster to generate. However, the fractal iteration for Orbital fractals is unaffected by the size of the image so the Orbital fractal iteration does not benefit from the smaller size. Still, all of the post-sample generation steps including Data Normalization, the data to color mapping handled by the Color Controllers, and image processing (smoothing, sharpening, embossing, anti-aliasing), are tied to the image size, so even Orbital fractals benefit to some degree from the smaller size. If you click on the image in the Preview Window, a new Fractal Window will open with a full-sized version of the preview. Toolbar Buttons
There are several toolbar buttons on the Preview Window that can be used to adjust the preview:
