To set caching options
1
Choose Layout > Display Options.
2
Select or deselect options in the Cache area (described next),
and click OK to implement the settings.
Draw with Cache option
Select this option to display low-resolution versions of cached
objects for faster display. Cached objects are objects that have been
cached with either the Cache Object command or the Auto Cache
Images option (described next).
When Draw with Cache is not selected, Canvas retains any low-reso-
lution previews that it has created in memory, but displays the full
paths of vector objects and displays paint objects at normal resolu-
tion.
Auto Cache Images option
Select Auto Cache Images to automatically cache paint objects
whose resolution is above a threshold that you specify.
To set the resolution threshold, enter a value from 72-2540 ppi in the
first text box. When the resolution of a paint object is equal to or
greater than the specified resolution, Canvas caches the paint object.
Cached paint objects are displayed at low resolution for faster dis-
play. Enter the desired display resolution in the second text box.
Note: If Auto Cache Images is selected, but Draw with Cache is not
selected, Canvas will cache paint objects (if their resolution is above
the threshold you set), but will not display the low-resolution ver-
sions.
To uncache all paint objects, deselect Auto Cache Images. A mes-
sage appears. Click Yes to uncache all paint objects. This is equiva-
lent to using the Uncache Object command on each paint object
individually.
Note: If you want to uncache paint objects and Auto Cache Images is
already cleared, use the Uncache Object command instead.
