Details¶

class Gsk.PathMeasure¶

Performs measurements on paths such as determining the length of the path.

Many measuring operations require sampling the path length at intermediate points. Therefore, a GskPathMeasure has a tolerance that determines what precision is required for such approximations.

A GskPathMeasure struct is a reference counted struct and should be treated as opaque.

Added in version 4.14.

classmethod new(path)¶

Parameters:: path (Gsk.Path) – the path to measure
Returns:: a new GskPathMeasure representing path
Return type:: Gsk.PathMeasure

Creates a measure object for the given path with the default tolerance.

Added in version 4.14.

classmethod new_with_tolerance(path, tolerance)¶

Parameters:

path (Gsk.Path) – the path to measure
tolerance (float) – the tolerance for measuring operations

Returns:

a new GskPathMeasure representing path

Return type:

Gsk.PathMeasure

Creates a measure object for the given path and tolerance.

Added in version 4.14.

get_length()¶

Returns:: the length of the path measured by self
Return type:: float

Gets the length of the path being measured.

The length is cached, so this function does not do any work.

Added in version 4.14.

get_path()¶

Returns:: the path of self
Return type:: Gsk.Path

Returns the path that the measure was created for.

Added in version 4.14.

get_point(distance)¶

Parameters:

distance (float) – the distance

Returns:

true if result was set

result:: return location for the point

Return type:

(bool, result: Gsk.PathPoint)

Gets the point at the given distance into the path.

An empty path has no points, so false is returned in that case.

Added in version 4.14.

get_tolerance()¶

Returns:: the tolerance of self
Return type:: float

Returns the tolerance that the measure was created with.

Added in version 4.14.

ref()¶

Returns:: the passed in GskPathMeasure.
Return type:: Gsk.PathMeasure

Increases the reference count of a GskPathMeasure by one.

Added in version 4.14.

unref()¶

Decreases the reference count of a GskPathMeasure by one.

If the resulting reference count is zero, frees the object.

Added in version 4.14.
