Canvas 12 User Guide
To open the Display Options manager:
Choose Layout | Display Options.
Save as default Any settings you select in the dialog box are saved as the default setup
for new documents.
Show The normal Canvas display shows all objects with their inks, strokes,
and other attributes as they are in the document.
Alert Gamut Warning: This mode highlights colors that are outside the
CMYK color gamut. It replaces out-of-gamut colors with a special
indicator color. Bright greeen is the default indicator color.
Ink Coverage: This mode shows all areas of the image that exceed a
specified ink coverage. Bright greeen is the default indicator color.
Preview Wireframe: Wireframe mode shows vector objects without their
assigned ink or stroke attributes. When Wireframe is selected, vector
objects are hollow and have 1-point black pen strokes. Text characters
appear solid black. Paint objects are hollow and only their bounding box
appears. With this mode, the screen display tends to speed up.
Pixel Mode: The Pixel Mode setting allows users to view graphics at 72
ppi before they are rendered.
When creating Web graphics, the standard resolution is 72 ppi. At the
same time, all of your images will remain fully editable. Pixel Mode also
prevents pixel shifting, which sometimes occurs when objects are
exported to the Web (see "Designing for the Web" on page 690).
Cache Caching in Canvas is a technique that can dramatically increase display
speed. When an object is cached, Canvas creates a low-resolution
version of the object to display on screen. This can make it much easier
to work in documents that contain complex vector objects or high-
resolution images, which can significantly slow down zooming and
scrolling.
When you are not editing cached objects, it usually won’t matter that
they are displayed at lower resolution. You’ll enjoy significantly faster
display without losing any capabilities. When you want to edit a cached
object, Canvas loads the original; you do not need to take any special
action or uncache the object.
Draw with Cache: 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 (see "Cache" on page 102).
