Image Preferences
Both image capture and image saving are subject to the settings in
the Image Preferences, shown below.
Settings in the Save dialog override those
in the preferences.

Image Preferences
The fields in this panel have the following meanings:
- Object Quality: Specifies
the image quality. Moving the slider toward the Realistic
end of the scale increases the file size and the time required to
generate the image file.
- Enlarge Width and Height by:
Set the default image scaling factor (as above).
- Background Color:
Background color for the image.
- Generic Pixel Format: Use
the system software renderer. This option should be checked only after
rendering problems/failures have been encountered during image capture
or printing.
- Gray Scale: Convert the
image to gray scale (i.e., black and white) before capturing. The
default is to save a color image.
- Render Method: Specify
the rendering method. The choices available in this menu are shown
above. This setting should seldom be changed.
