Basic Compositing

Note: Setting an object’s scale to a negative value flips the object.

Shear: Defines the X and Y shear of the object. An object with no shear has X and Y
shear values of 0. Positive values shear in one direction, while negative values shear in
the other.

Anchor Point: Defines the X and Y position of the anchor point relative to the center of
the object. Coordinates of 0,0 center the anchor point in the bounding box defining
the outer edge of the object.

Opacity: Defines the transparency of the object. For more information, see “

Editing

Opacity and Blending

” on page 243.

Blend Mode: Sets the Blend Mode of the object. For more information, see “

Editing

Opacity and Blending

” on page 243.

Preserve Opacity: When this checkbox is turned on, the object appears only where
another object is visible below it in the composite. The object uses the opacity value of
the object below it. For more information, see “

The Preserve Opacity Option

” on

page 247.

Drop Shadow: Turns the drop shadow of an object on and off. For more information
about working with drop shadows, see “

Drop Shadows

” on page 269.

Four Corner: Turns corner-pinning on and off. If an object has been corner-pinned and
this checkbox is turned off, the object resumes its original shape, although the corner-
pinning coordinates are maintained. Turning the checkbox back on re-enables the
corner-pinning effect specified by the Four Corner coordinate parameters.

Click the disclosure triangle to display four two-dimensional parameters that define the
polygonal transform of a corner-pinned object. Individual parameters for the Bottom
Left, Bottom Right, Top Right, and Top Left corners of the bounding box that surrounds
an object have individual X and Y coordinates.
