Struct TilingPattern

pub struct TilingPattern<'a> { /* private fields */ }

Writer for a tiling pattern stream.

This struct is created by Chunk::tiling_pattern.

Implementations

impl<'a> TilingPattern<'a>

pub fn paint_type(&mut self, paint_type: PaintType) -> &mut Self

Write the /PaintType attribute.

Sets whether to use external or stream color. Required.

pub fn tiling_type(&mut self, tiling_type: TilingType) -> &mut Self

Write the /TilingType attribute.

Sets how to stretch and space the pattern. Required.

pub fn bbox(&mut self, bbox: Rect) -> &mut Self

Write the /BBox attribute.

Sets the bounding box of the pattern in the pattern’s coordinate system. Required.

pub fn x_step(&mut self, x_step: f32) -> &mut Self

Write the /XStep attribute.

Sets the horizontal spacing between pattern cells. Required.

Panics if x_step is zero.

pub fn y_step(&mut self, y_step: f32) -> &mut Self

Write the /YStep attribute.

Sets the vertical spacing between pattern cells. Required.

Panics if y_step is zero.

pub fn resources(&mut self) -> Resources<'_>

Start writing the /Resources dictionary.

Sets the resources used by the pattern. Required.

pub fn matrix(&mut self, matrix: [f32; 6]) -> &mut Self

Write the /Matrix attribute.

Maps the pattern coordinate system to the parent content stream coordinates. The default is the identity matrix.

Methods from Deref<Target = Stream<'a>>

pub fn filter(&mut self, filter: Filter) -> &mut Self

Write the /Filter attribute.

pub fn decode_parms(&mut self) -> DecodeParms<'_>

Start writing the /DecodeParms attribute.

This is a dictionary that specifies parameters to be used in decoding the stream data using the filter specified by the /Filter attribute.

Methods from Deref<Target = Dict<'a>>

pub fn len(&self) -> i32

The number of written pairs.

pub fn is_empty(&self) -> bool

Whether no pairs have been written so far.

pub fn insert(&mut self, key: Name<'_>) -> Obj<'_>

Start writing a pair with an arbitrary value.

pub fn pair<T: Primitive>(&mut self, key: Name<'_>, value: T) -> &mut Self

Write a pair with a primitive value.

This is a shorthand for dict.insert(key).primitive(value).

pub fn pairs<'n, T: Primitive>( &mut self, pairs: impl IntoIterator<Item = (Name<'n>, T)>, ) -> &mut Self

Write a sequence of pairs with primitive values.

Trait Implementations

impl<'a> Deref for TilingPattern<'a>

type Target = Stream<'a>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> DerefMut for TilingPattern<'a>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
