Struct ShadingPattern 

pub struct ShadingPattern {
    pub name: String,
    pub shading: ShadingDefinition,
    pub matrix: Option<[f64; 6]>,
}

Shading pattern that combines a shading with pattern properties

Fields

name: String

Pattern name for referencing

shading: ShadingDefinition

The underlying shading

matrix: Option<[f64; 6]>

Pattern transformation matrix

Implementations

impl ShadingPattern

pub fn new(name: String, shading: ShadingDefinition) -> Self

Create a new shading pattern

pub fn with_matrix(self, matrix: [f64; 6]) -> Self

Set pattern transformation matrix

pub fn to_pdf_pattern_dictionary(&self) -> Result<Dictionary>

Generate PDF pattern dictionary for shading pattern.

NOTE: ShadingPattern is not yet wired through Page → writer (there is no Page::add_shading_pattern and the writer iterates only page.shadings()), so this method is not exercised by the serialisation pipeline today. The sh direct-paint path ([GraphicsContext::paint_shading] over [Page::add_shading]) is the wired, end-to-end gradient path. Because the inlined /Shading here carries its /Function inline (the writer’s indirect-hoist only applies to page.shadings()), full PatternType-2 fill support remains a follow-up.

pub fn validate(&self) -> Result<()>

Validate shading pattern
