Struct Path

source
pub struct Path { /* private fields */ }
Expand description

A simple path data structure.

§Custom attributes

Paths can store a fixed number of extra f32 values per endpoint, called “custom attributes” or “interpolated attributes” through the documentation. These can be handy to represent arbitrary attributes such as variable colors, line width, etc.

See also:

§Representation

Paths contain two buffers:

  • a buffer of commands (Begin, Line, Quadratic, Cubic, Close or End),
  • and a buffer of pairs of floats that can be endpoints control points or custom attributes.

The order of storage for points is determined by the sequence of commands. Custom attributes (if any) always directly follow endpoints. If there is an odd number of attributes, the last float of the each attribute sequence is set to zero and is not used.
