Micro-PWC OPERATOR’S MANUAL
Using Graphic Displays 75
7.6.1 The Pan Operations: Up, Down, Left, Right, Center
The Pan operations (Up, Down, Left, Right, Center) are used to change the portion of the view shown in
the Operator Window; they do not change the view size.
Each of the Pan functions is represented on the Zoom/Pan window by a button. The face and location of
the button indicate its function. The face of each of the directional operations (Up, Down, Left, and Right)
contains an arrow pointing in the appropriate direction, and each button is located in the appropriate posi-
tion around the Center button. The face of the Center button contains a bull’s eye.
Each click on one of the directional Pan buttons moves the visible portion of the view in the selected direc-
tion by 1/3 of the corresponding view dimension.
After the Center button is clicked, the pointer assumes the shape of a bull’s eye. The next click in the
graphic display will center the view on the point clicked.
7.6.2 The Zoom Operations: In, Out, Fit, Pick
The Zoom operations (In, Out, Fit, Pick) change the apparent size of the graphic which appears in the
Operator Window.
A Graphic Display can have a maximum size of 400 by 300 units, and a minimum size of 20 by 15 units.
The number of units in a graphic is normally invisible to the user, except during configuration (discussed in
the Micro-PWC Configuration Guide) because installed graphics are automatically zoomed to fit when
loaded in the Operator Window. Attempts to Zoom In or Out beyond the minimum or maximum size of a
graphic display will have no effect, and the view size will remain at the minimum or maximum.
Each time Zoom In is clicked, the view size is reduced by 62%. The center of the view remains unchanged.
Objects in the graphic which are visible appear correspondingly larger. If the view has been fully zoomed
in, no further change occurs to the view size.
Each time Zoom Out is clicked, the view size is enlarged by 62%. The center of the view remains
unchanged. Objects in the graphic which are visible appear correspondingly smaller. If the view has been
fully zoomed out, no further change occurs to the view size.
Click Zoom Fit to adjust the view size by automatically zooming out (or in) so that the entire model is visi-
ble and fills the Working View. If there are no objects outside the current view size, the view size will “zoom
in” in order to make the objects present fill the Operator Window. (However, it will not zoom in beyond the
default view size, which is 100 by 75 units.) Each time an installed graphic is displayed in an Operator Win-
dow a Zoom Fit operation is automatically performed.
The Zoom Pick button allows you to select two diagonal corners (e.g., the lower left and upper right cor-
ners) of the box which encompasses the desired view size. The rectangle resulting from these selections is
called the zoom box. If a zoom box is smaller than the minimum permissible view size, the view size will
remain unchanged.
✎ NOTE
Changes to the view size made in a graphic will not be saved as
part of a CRT Context Key or Quick Key setting; when a graphic
display is called up by either of these methods, a zoom-to-fit
operation (described in
Section 7.6.2, The Zoom Operations: In,
Out, Fit, Pick ) will automatically be performed.
