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.
