- SAVER DESCRIPTION
-
- The OpalVision saver gives you control over the OpalVision display
- board from within ADPro or MorphPlus. The saver allows raw 24bit or
- grey scale images or rendered images from 2 to 256 colours to be
- displayed.
-
- When the Saver is activated, the OpalVision Saver control panel is
- displayed. This control panel contains several button to control the
- image being displayed.
-
- The uppermost button indicates type of image to be displayed. This
- button allows you to switch between the raw 24bit or grey scale image
- and the rendered image if one exists. The rendered image data can
- contain 1 to 8 bit-planes (2 to 256 colours) in a standard palette
- mapped configuration. That is, the rendered image data cannot be in
- one of the rendering modes unique to the Amiga such as HAM, HAM8 or
- EHB.
-
- Below this button are the resolution control buttons. These three
- buttons control the horizontal resolution, vertical resolution and
- overscan respectively. These buttons are much the same as the screen
- control buttons on ADPro's main screen. The Overscan button controls
- both the hoizontal and vertical.
-
- To view the image using the current settings, select the Image button.
- Once the image has been displayed, the saver will accept the following
- key commands:
-
- Del : Toggle cross hair pointer on/off.
- Arrow Keys : Scroll display.
- Shift - Arrow Keys: Scroll display in larger steps.
- Alt - Arrow Keys : Jump to the extremeties of the image.
- n : Center screen under mouse pointer (if possible).
-
- The scroll keys are only applicable if the image is larger than the
- display screen size.
-
- To exit the saver click the left mouse button and you will be returned
- to ADPro's main screen.
-
- Note: Any changes made with the Color Balancing controls on ADPro's
- main screen will effect the displayed image immediately without the
- need the re-render it or use the Apply Map Operator.

-
- Hires (1)
- Interlace (2)
- Horizontal Overscan (8)
- Vertical Overscan (16)

- will put the display into overscan mode. If SCREEN_TYPE is not
- specified, the last selected display resolution will be used.
-
- If the DURATION token is specified, it must be followed by a duration
- in ticks (fiftieths of a second) to display the image. If TICKS is 0
- or DURATION is not specified, the image will be displayed until the
