Implementations

impl ContourMeasure

pub fn length(&self) -> scalar

Returns the length of the contour.

pub fn pos_tan(&self, distance: scalar) -> Option<(Point, Vector)>

Pins distance to 0 <= distance <= length(), then computes the corresponding position and tangent.

• distance: distance along the contour.

pub fn get_matrix( &self, distance: scalar, flags: impl Into<Option<MatrixFlags>>, ) -> Option<Matrix>

Pins distance to 0 <= distance <= length(), then computes the corresponding matrix (by calling Self::pos_tan()).

Returns None if there is no path, or a zero-length path was specified.

• distance: distance along the contour.
• flags: controls whether position, tangent, or both are computed.

pub fn segment( &self, start_d: scalar, stop_d: scalar, path_builder: &mut PathBuilder, start_with_move_to: bool, ) -> bool

👎Deprecated since 0.94.0: Use get_segment()

Given a start and stop distance, appends the intervening segment(s) to path_builder.

If the segment is zero-length, returns false; otherwise returns true. start_d and stop_d are pinned to legal values (0..length()). If start_d > stop_d, returns false and leaves path_builder untouched.

Begins the segment with a move_to if start_with_move_to is true.

• start_d: start distance along the contour.
• stop_d: stop distance along the contour.
• path_builder: destination that receives the segment.
• start_with_move_to: whether to begin with move_to.

pub fn get_segment( &self, start_d: scalar, stop_d: scalar, path_builder: &mut PathBuilder, start_with_move_to: bool, ) -> bool

Given a start and stop distance, appends the intervening segment(s) to path_builder.

If the segment is zero-length, returns false; otherwise returns true. start_d and stop_d are pinned to legal values (0..length()). If start_d > stop_d, returns false and leaves path_builder untouched.

Begins the segment with a move_to if start_with_move_to is true.

• start_d: start distance along the contour.
• stop_d: stop distance along the contour.
• path_builder: destination that receives the segment.
• start_with_move_to: whether to begin with move_to.

pub fn is_closed(&self) -> bool

Returns true if the contour is closed.

pub fn verbs(&self) -> ForwardVerbIterator<'_>

Returns an iterator over measurement data for the contour’s verbs.
