Methods

GrapheneSize (Handle = null)

Allocates a new #graphene_size_t. The contents of the returned value are undefined.
- @p Handle is an optional native handle or wrapper whose handle to adopt; when the native constructor is called.
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.
equal (object b)

Checks whether the two give #graphene_size_t are equal.
- @p b is a #graphene_size_t.
- @r true if the sizes are equal.
free ()

Frees the resources allocated by graphene_size_alloc().
- @r None.
init (double width, double height)

Initializes a #graphene_size_t using the given @width and @height.
- @p width is the width.
- @p height is the height.
- @r the initialized #graphene_size_t.
init_from_size (object src)

Initializes a #graphene_size_t using the width and height of the given
- @src. ``
- @p src is a #graphene_size_t.
- @r the initialized #graphene_size_t.
interpolate (object b, double factor)

Linearly interpolates the two given #graphene_size_t using the given interpolation @factor.
- @p b is a #graphene_size_t.
- @p factor is the linear interpolation factor.
- @p res is return location for the interpolated size.
- @r None.
scale (double factor)

Scales the components of a #graphene_size_t using the given @factor.
- @p factor is the scaling factor.
- @p res is return location for the scaled size.
- @r None.

class: GrapheneSizeLayout

[12:14] static extends: object

Methods

layout ()

Returns the Panama struct layout for Size.
