Chapter 2: Documents and Setup
When Draw with Cache is not selected, Canvas retains any low-
resolution previews that it has created in memory, but displays the full
paths of vector objects and displays paint objects at normal resolution.
Auto Cache Images: Select Auto Cache Images to automatically cache
paint objects whose resolution is above a threshold that you specify.
If Auto Cache Images is selected, but Draw with Cache is not
selected, Canvas will cache paint objects (if their resolution is
above the set threshold), but will not display the low-resolution
versions.
Cached paint objects are displayed at low resolution for faster display.
Enter the desired display resolution in the second text box.
To uncache all paint objects, deselect Auto Cache Images. A message
appears. Click Yes to uncache all paint objects. This is equivalent to
using the Uncache Object command on each paint object individually.
If you want to uncache paint objects and Auto Cache Images is
already cleared, use the Uncache Object command instead (see
"To uncache an object:" on page 104).
Document Resolution 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.
To change the Gamut Warning color:
Choose Edit | Calibration | Gamut Warning. Select a color from the pop-up menu.
To change the ink coverage color or value:
Choose Edit | Calibration | Ink Coverage. Select a color from the menu. Enter an amount
percentage value in the Amount box.
Caching objects
This command can be used to speed up the display of complex objects, which is useful when a
document contains complex objects that you do not need to edit often. When you cache an object,
Canvas stores a low-resolution preview in memory. The preview can be displayed quickly when you
move the object or change views. You can cache any type of object for faster display.
