Struct LinearGradientBuilder 

pub struct LinearGradientBuilder { /* private fields */ }

Builder for linear (axial) gradients.

Creates PDF Type 2 (Axial) shading that interpolates colors along a line between two points.

Implementations

impl LinearGradientBuilder

pub fn new() -> Self

Create a new linear gradient builder.

pub fn from(self, x: f32, y: f32) -> Self

Set the start point of the gradient.

pub fn to(self, x: f32, y: f32) -> Self

Set the end point of the gradient.

pub fn add_stop(self, position: f32, color: Color) -> Self

Add a color stop.

pub fn extend_start(self, extend: bool) -> Self

Set whether to extend the gradient before the start point.

pub fn extend_end(self, extend: bool) -> Self

Set whether to extend the gradient after the end point.

pub fn extend(self, extend: bool) -> Self

Set both extend flags.

pub fn two_color(start_color: Color, end_color: Color) -> Self

Build a simple two-color gradient.

pub fn build(&self) -> (Object, Option<Object>)

Build the shading dictionary as a PDF Object.

Returns a tuple of (shading_dict, function_dict) where function_dict may be None for simple two-color gradients.
