Detailed Description

This structure contains information passed to each XCanvas render operation.

This structure contains information considered as the render state, i.e. the common setup required to render each individual XCanvas primitive.

Since: OOo 2.0

◆ AffineTransform

::com::sun::star::geometry::AffineMatrix2D AffineTransform

The affine transform associated with this render operation.

This is used to transform coordinates of canvas primitives from user space to view space (from which they are subsequently transformed to device space by the view transform).

◆ Clip

XPolyPolygon2D Clip

The clipping area associated with this render operation.

This clipping is interpreted in the user coordinate system, i.e. subject to the render state transform followed by the view transform before mapped to device coordinate space.

Specifying an empty interface denotes no clipping, i.e. everything rendered to the canvas will be visible (subject to device-dependent constraints, of course). Specifying an empty XPolyPolygon2D, i.e. a poly-polygon containing zero polygons, or an XPolyPolygon2D with any number of empty sub-polygons, denotes the NULL clip. That means, nothing rendered to the canvas will be visible.

◆ CompositeOperation

byte CompositeOperation

The composition mode associated with this render operation.

The composite mode determines in which way the primitive and possibly existing background is combined. The permissible values must be one out of the CompositeOperation constants.

◆ DeviceColor

sequence<ColorComponent> DeviceColor

The device color associated with this render operation.

Note that this need not be RGB here, but depends on the active device color space.
