Desktop Manager: Zoom Settings (Windows 98)
• Perform Smooth Scaling: (Windows 2000/NT 4.0 only) You can enable
Perform Smooth Scaling for a “smooth” zoomed view. This option, disabled
by default, causes the hardware to perform filtering when displaying the
zoomed view. Filtering reduces the “blockiness” and hard edges caused by
greatly magnifying the display; however the resulting view may appear fuzzy
and is generally undesirable for applications such as photo and image editing.
• Hot Keys to Control Zoom: Figure 9.22 shows user-modified Zoom hot
keys. To specify hot key combinations other than the defaults, you can follow
the steps described in the section “Hot Keys” on page 114.
•
Toggle zoom on and off: Press Alt + 4 (default) or any other key you’ve
specified to turn zoom on and off. (To enter ‘None’, press the space bar.)
•
Increase magnification level: If None appears in this field, specify a key
or key combination as described earlier.
•
Decrease magnification level: If None appears in this field, specify a key
or key combination as described earlier.
• Zoom update frequency: The magnified view is updated whenever the
mouse cursor is moved and is updated at a fixed interval when the mouse
cursor is still. The update or “refresh” rate of the zoomed view is
configurable and can be set from one to 100 times per second.
