Interface: ShapeProperties

A shape's visual properties (a:spPr, CT_ShapeProperties): its a:xfrm placement together with geometry, fill, line, and effects.

Every field is optional — an unset field inherits (from the placeholder, the style reference, or the theme). The a:xfrm lives here (not on the ShapeNode) so a placeholder shape resolves its whole spPr — placement included — as one unit down the layout → master chain. The node exposes it uniformly across content kinds via ShapeNode::transform. a:effectDag is not modeled, only a:effectLst.

Properties

Property	Description
transform ShapeTransform | null	a:xfrm — where the shape sits, how big it is, and its rotation/flip. None is unspecified — a placeholder shape inherits it down the layout → master chain.
geometry ShapeGeometry | null	a:prstGeom / a:custGeom — the outline.
fill PaintFill | null	The interior fill — the EG_FillProperties choice.
line PaintLine | null	a:ln — the outline stroke.
effects PaintEffectList | null	a:effectLst — shadow/glow/reflection/etc.
scene3d PaintScene3d | null	a:scene3d — the 3-D scene.
shape3d PaintShape3d | null	a:sp3d — the 3-D shape extrusion.
