centeroff

Centeroff is a parameter used in computer graphics, UI layout, and related fields to represent the offset between the geometric center of an object and a chosen reference point or anchor. It is typically expressed as centeroffX and centeroffY, the horizontal and vertical components indicating how far the center is shifted from the reference.

In practice, centeroff is used to refine alignment when the visual center does not match the object's bounding box or when elements must be positioned relative to a non-centered anchor. In code, centeroff appears as a variable or property that is applied during rendering or transformation.

Common scenarios include placing sprites with centered visuals on a grid, aligning UI panels whose content is centered but whose hit area is offset, and implementing animations that pivot objects around a non-origin point. The term is informal and appears across various development environments rather than as a formal standard. Variants include centeroffX and centeroffY, or the more general centerOffset.

Etymology: a contraction of center and offset. Notes: when rotation or scaling is involved, centeroff must be adjusted to account for the changed center. See also anchor point, origin, pivot, alignment.
