Rendering images

Rendering fractals to disk is the preferred way of exporting your artwork to bitmap images, ready for printing or publishing on the web.

To render the fractal in an open fractal window to disk, click Render to Disk on the Fractal menu.

Click the Add button on the Render to Disk tool window to render a parameter set to disk. Hold down the button and click Add Fractal to specify a fractal file to render.

This will open the Render to Disk dialog box. Here, you can specify a file name and file format for the image, the desired size and resolution, and the anti-aliasing settings. To get help on a control in the dialog box, click the ? button in the title bar, and then click the control.

Click OK to start rendering the fractal. This will create a new render job that starts calculating the image in the background. Render jobs can be monitored and managed in the Render to Disk tool window. See Render jobs.


  • You can also render fractals and parameter sets directly from the browser by right-clicking them and clicking Render to Disk, or by dragging them from the browser to the Render to Disk tool window. See Opening files and entries.
  • The resolution specified when starting a render job is used to calculate the desired size in pixels if you enter the width and height of the image in cm or inches. See Resolution.
  • When rendering very large images, you can use the Split into tiles option to automatically split the rendered image into multiple rectangular tiles, labeled A1, A2, B1, B2, and so on. This helps to keep the size of the individual image files at a reasonable level for any post-processing. You can later stitch the tiles together with software such as Adobe Photoshop.
  • Check the Force Linear drawing method option for the highest image quality. This forces Ultra Fractal to use the One-pass linear option as the drawing method in all layers of the fractal to be rendered. In this way, you can work on the fractal with the Guessing drawing method for convenience without having to change the drawing method for a final render.
  • Always save your fractals as a parameter set or a fractal file as well. Rendered images do not contain any fractal information and Ultra Fractal will not be able to open them later.
