858 Chapter 22: Customizing the User Interface
When Safe Frames are displayed in the v iewport
and a bitmap image is assigned as a viewport
background (page 1–38) using either the
Match Viewport or Match Rendering Output
options, the image is confined to the Live area
of the safe frames and matches the rendered
background. This assumes that the same bitmap
is assigned to the Environment background using
Environment/Screen coordinates.
You can toggle the status of safe frames (page
3–1030) on or off for the current viewport,
andusetheSafeFramespaneloftheViewport
Configuration dialog to adjust the parameters.

are using a background image in your rendering,
make sure your rendering output size matches the
background image size. This will avoid distortion.

these parameters independently. Default=10%.

this is smaller than the Action frame. The Lock
