Enum Pattern 

#[non_exhaustive]
pub enum Pattern {
    Tiling(Box<TilingPattern>),
    Shading(Box<ShadingPattern>),
}

A loaded pattern.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Tiling(Box<TilingPattern>)

/PatternType 1: a content stream tiled across the fill.

Shading(Box<ShadingPattern>)

/PatternType 2: a shading painted across the fill.

Implementations

impl Pattern

pub fn matrix(&self) -> Affine

The matrix taking the pattern’s own space to the parent’s.

pub fn load<R: Resolve>( obj: &Object, parent_matrix: Affine, resources: Option<&Dict>, r: &R, functions: &mut FunctionCache, limits: &Limits, diags: &mut Diagnostics, ) -> Option<Self>

Load a pattern from the object a /Pattern resource names.

parent_matrix is the form’s or page’s coordinate system, not the current transformation matrix. Dispatch is on /PatternType: 1 is tiling, 2 is shading, and anything else — including a missing key — yields no pattern at all.

There is no pattern cache. A pattern is loaded afresh at each use, so the parent_matrix a use is given is the one it gets.
