class: GskPathMeasure

[16:7] extends: object

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.

Methods

GskPathMeasure (path = null, tolerance = null)

Creates a measure object for the given @path with the default tolerance.
- @p path is the path to measure.
- @p tolerance is the tolerance for measuring operations.
toNativeHandle (Source)

Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.
- @p Source is the raw handle, raw buffer, wrapper, or null.
- @r A raw pointer carrier or null when no pointer is present.
getLib ()

Returns the opened native library for this generated wrapper.
- @r The opened native library.
handle ()

Returns the wrapped NativeHandle.
- @r The wrapped NativeHandle.
isNull ()

Returns true when the wrapped handle is null.
- @r A bool.
describe ()

Returns a small string for debugging generated wrappers.
- @r A string.
get_length ()

Gets the length of the path being measured. The length is cached, so this function does not do any work.
- @r the length of the path measured by @self.
get_path ()

Returns the path that the measure was created for.
- @r the path of @self.
get_tolerance ()

Returns the tolerance that the measure was created with.
- @r the tolerance of @self.
ref ()

Increases the reference count of a GskPathMeasure by one.
- @r the passed in GskPathMeasure..
unref ()

Decreases the reference count of a GskPathMeasure by one. If the resulting reference count is zero, frees the object.
- @r None.
