Geometry interfaces
Geometry interfaces is a CSS module that provides interfaces for working with 3D and 2D graphics — in particular, for working with points, rectangles, quadrilaterals and transformation matrices (for operations that translate/move, scale, rotate, skew/shear/slant, and flip graphics, as well as for multiplying/chaining and inverting/undoing those operations).
As a web developer, you don't always use the geometry interfaces directly, but instead use other features that rely on them behind the scenes: parts of CSS Transforms, the Canvas API, the WebXR Device API, and (more directly) VideoFrame.visibleRect, Element.getClientRects(), and Element.getBoundingClientRect().
Interfaces
DOMMatrix-
Represents a transformation matrix, for operations that translate/move, scale, rotate, skew/shear/slant, and flip graphics, as well as for multiplying/chaining and inverting/undoing those operations.
DOMMatrixReadOnly-
Read-only version of
DOMMatrix. DOMPoint-
Represents a 2D or 3D point in a coordinate system; it includes values for the coordinates in up to three dimensions, as well as an optional perspective value.
DOMPointReadOnly-
Read-only version of
DOMPoint. DOMQuad-
Represents a collection of four
DOMPointobjects defining the corners of a quadrilateral. DOMRect-
Represents the size and position of a rectangle.
DOMRectReadOnly-
Read-only version of
DOMRect.
Examples
The Path2D.addPath() and CanvasPattern.setTransform() articles have examples that use some of the geometry interfaces.
