Saving Rendered Images

You can save your rendered images to disk using the Save Image dialog, which is primarily used with display styles. For saving photo-realistic images, use the Luxology Render dialog, which provides a wider range of post-processing options and a superior preview interface.

In addition, you can use the Save Multiple Images dialog to render multiple images and save them to disk. This can be done from within the OpenUtilities Substation environment or from the system command line. The Save Multiple Images dialog can be used for either display styles or photo-realistic rendering.

You can save rendered images as follows:

  • Recommended: Saving an image, which is done by choosing the Save Image dialog. You can save true-color images (also referred to as 24-bit or 16.7 million color images) that display or print in full color on a system with that capability, even if you do not have a true-color display. Images also can be rendered and saved at resolutions higher than the resolution of the screen. There is a tiled rendering option that is useful for overcoming memory limitations when saving large images. Tiled rendering can be performed by multiple systems over a network.
  • Screen Capture is performed by choosing the Screen Capture dialog. Images saved in this way are limited to screen resolution and the number of displayable colors.

Screen Capture and Dithering

If your system cannot simultaneously display all the required colors, rendered images are dithered to simulate the extra colors. Dithering is the creation of a pattern of pixels, using available colors, to approximate any unavailable color(s).

With screen capture you are limited to the number of colors and resolution your monitor can display. You should save images rather than use screen capture if a high-quality image is required.
