Selecting Frozen overrides a lens relative viewpoint; the lens will
show the same view after being moved. If you deselect Frozen, the
lens will display the new viewpoint location.
Using the Frozen option
1
Select a lens.
2
In the SpriteEffects palette, click the Frozen option to select it.
The lens is frozen when a check mark appears in the Frozen box.
3
To update the view in a lens to show the current viewpoint,
click the Frozen option to clear the check mark.
Sharing SpriteEffects
Because SpriteEffects are live effects that can be edited and
updated, there are a few issues to consider if you plan to share docu-
ments that contain SpriteEffects.
Effects that are applied to an object need to be available to other Can-
vas users if they share the document and need to edit the effects. If
you use only built-in Canvas effects, this is not a problem. If you use
third-party plug-ins to apply effects, other users must have the same
plug-ins installed. Without the plug-ins, they cannot edit effects
applied in a Canvas document.
This issue is similar to the issue of font availability in shared docu-
ments. If a document contains text, the same fonts must be installed
by all users who share the document.
If you export a document using an image file format, the effects will
be rendered into an image (as described below), and the effects plug-
ins will no longer be needed. Rendering is necessary because other
file formats do not support SpriteEffects on objects.
Platform considerations
When it comes to using effects plug-ins, you should not have a prob-
lem when sharing documents on the same platform (Mac OS or Win-
dows), as long as everyone who views the document has the same
plug-ins installed.
If you share documents across platforms, however, compatibility
among third-party plug-ins even ones with the same names is
not guaranteed.
Tip
Freezing lenses can avoid slow
performance when you edit
objects shown in lenses. When
you finish editing, select the
lenses and deselect the Frozen
option to update the lens
views.
