ADPro/MorphPlus OpalVision Saver v1.4
INSTALLATION
To install the saver, use the supplied Install script from the cli.
First make sure that you set the current directory to the directory
where you extracted this archive. You must specify the directory into
which ADPro is installed, if you have assigned ADPro: then use the
command.
execute Install ADPro:
If you haven't assigned ADPro, then specify the path that contains
ADPro, if the path name does not end in ':' then you must specify a
'/' after the path name, for example:
execute Install dh0:graphics/adpro/
execute Install dh0:
NOTE: If the installer tells you to reboot, then you must reboot your
amiga before using the OpalVision Saver.
TECHNICAL NOTE: You must have version 1.6 or later of opal.library,
the install script will make sure of this. If you find that the saver
crashes, make sure you have version 1.6 or later by typing:
version opal.library
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.
AREXX INTERFACE
Syntax: SAVE FILENAME TYPE
SAVE FILENAME TYPE SCREEN_TYPE STYPE
SAVE FILENAME TYPE SCREEN_TYPE STYPE DURATION TICKS
The FILENAME parameter must be specified but is ignored by the saver.
The TYPE parameter is also required and defines the image type to
display, accepted values are RAW or IMAGE, SCREEN is not supported by
the saver.
If the SCREEN_TYPE token is specified, it must be followed by a value
indicating the display resolution to use (STYPE), this value is the
same as ADPro's screen type flags given in table 16.5 of the ADPro
manual. Allowable flags are:
Hires (1)
Interlace (2)
Horizontal Overscan (8)
Vertical Overscan (16)
Note that either Horizontal overscan (8) or 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
user clicks the left mouse button.
Examples:
1. Display Raw image data in hires-interlaced mode.
SAVE "X" RAW SCREEN_TYPE 3
2. Display Rendered image data in lores-overscan for 2 seconds.
SAVE "X" IMAGE SCREEN_TYPE 8 DURATION 100
