Using Displays
Pan and Zoom
You can step between these levels by using the following key
combinations:
•
Pause-Page Up
to zoom in
•
Pause-Page Down
to zoom out
The three zoom levels are described as follows:
•
Zoom to Fit
With the zoom-to-fit view, four pixels from the image in the
emulated frame buffer are merged into one pixel on the display.
This reduces the size of the image to one quarter of the actual
size so that you can view the whole image. Objects may appear
very small on some displays. This view becomes practical when
using a video projector or large format display. The zoomed out
image cannot be panned.
The zoom-to-fit view may leave large blank borders around the
image if, for example, you display a 1024 x 768 image on a 800
x 600 display. In this case, the quarter-size image would only
occupy the center 256 x 192 pixels on the display.
Note
When you start OpenWindows or CDE with an emulated frame buffer image
larger than the display, the internal display is automatically zoomed to fit so that
you can view the whole image. This may leave large blank borders around the
image which does not indicate a system fault. Press
Pause-Page Down
and
the image will be zoomed to fill the display.
•
One to One
With the one-to-one view, one pixel in the emulated frame buffer
image is displayed as one pixel on the display. If the emulated
frame buffer contains an image that is larger than the physical
display, you can view hidden parts of the image by panning.
