Section 8 — Picture Frame Menu
Corner Pinning Menu
The Corner Pinning feature allows you to move the corners of a source
image relative to the background. Krystal corner pinning is based on
source, not target, space. The new corner locations need not form a rect-
angle. Corner pinning is accomplished by distorting the source image to fit
into its newly defined corners. The modified image remains in its original
source plane, and is not “bent” along the Z axis. Corner pinning is key-
frameable, with all standard path control functions.
Press the Picture Frame top menu button then press the CORNER PINNING >
button to bring up the following menu:
CORNER PINNING— turns corner pinning on or off. When ON , the various
corner pinning controls appear on the screen. When OFF , a corner pinned
source image reverts to a non-corner pinned state.
CROP MODE— selects the following operating modes:
USER — Establishes a relationship between Corner Pinning and Crops
that uses corner pinned values to determine the source image area.
Crop values (controlled by the Crop menu) are used to select which
portion of the source image appears in the corner pinned area.
PRESET — Established a relationship between Corner Pinning and
Preset Crops, similar to above. Preset Crop is controlled via
