4.2 Initialize
The initialize function allows the user to clear specified
memory and graphics planes and/or initialize the display
mapping to a linear mapping. If the user selects the main
window, or the plane radio button in conjunction with the
all planes toggle button, the user is prompted for verification
of the action. Selecting OK from the verification box continues with
the initialization process; selecting Cancel closes the initialization
panel without taking any further action.
The main window, plane, and mapping radio buttons
allow the user to select the type of initialization to be done.
- Main Window:
- Initialize the entire display. All image and graphics
planes are cleared and the mapping is initialized to a
linear mapping.
- Plane:
- Allow the user to choose which image planes are to be
cleared. A single image plane or all image planes may be cleared.
To change the current image plane, the user must click the left
mouse button on the rotator icon. To clear all image
planes, the toggle button labeled All Planes
must be selected.
- Mapping:
- Initialize the mapping of the display. Initializing the mapping
consists of loading a linear or identity mapping.
- Rotator Icon:
- Select the image plane to be cleared. Clicking the left mouse button on
the icon increments the current plane number by one. The plane number
continues to be incremented until the maximum plane number is reached, at
which point the current plane number becomes the letter "G" indicating
the graphics planes are to be cleared. By clicking the left button on the
rotator again, the plane number returns to 1. The maximum
plane number is determined by the currently defined memory
configuration (see the Layout function found
on the Setup menu).
- Current Plane Number:
- The current plane number text box shows the user the currently
selected plane number. This may be modified by using the
rotator icon (see description above). The current plane
number is meaningful only when the plane radio button has
been selected.
- All Planes:
- When selected, all currently defined image planes will be cleared. If
this toggle button is not set, only the image plane indicated by the
text box next to the rotator icon is cleared. This toggle button is
displayed only when the plane radio button has been selected.
- Apply:
- Close the intialize panel and perform the specified initialization task.
- Cancel:
- Close the initialize panel without taking any action.
