Parameters for a tiled pattern fill.

Fields

path: PsPath

The path to fill with the pattern.

fill_rule: FillRule

Fill rule for the path.

tile: DisplayList

Pre-rendered display list for a single tile.

pattern_matrix: Matrix

Pattern matrix (pattern space → device space).

bbox: [f64; 4]

Bounding box of one tile in pattern space.

xstep: f64

Horizontal step between tile origins.

ystep: f64

Vertical step between tile origins.

paint_type: i32

Paint type: 1 = colored, 2 = uncolored.

underlying_color: Option<DeviceColor>

For uncolored patterns, the fill color.

pattern_id: u32

Unique pattern ID from pattern_store (for dedup in PDF output).

device_space_tile: bool

When true, tile display list elements have CTMs in device space (the pattern matrix is already baked into element transforms). When false, elements are in pattern space and the renderer applies the pattern_matrix during rendering.

flip_tile_y: bool

When true, the tile content was designed for a Y-flipped coordinate system (pattern matrix had negative d). The pre-rendered tile must be vertically flipped before stamping.

stroke_params: Option<StrokeParams>

For pattern strokes: stroke parameters to expand the centerline path into a fill outline for masking. When Some, path is a user-space stroke centerline rather than a fill path.

overprint_mode: i32

PDF overprint mode (0 or 1). When 1, CMYK(0,0,0,0) pixels in tile images are transparent (no ink = don’t paint).

Trait Implementations

impl Clone for PatternFillParams

fn clone(&self) -> PatternFillParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
