Struct usvg::ConvolveMatrix

pub struct ConvolveMatrix { /* fields omitted */ }

A convolve matrix representation.

Used primarily by FeConvolveMatrix.

Implementations

impl ConvolveMatrix

pub fn new(
    target_x: u32,
    target_y: u32,
    columns: u32,
    rows: u32,
    data: Vec<f64>
) -> Option<Self>

Creates a new ConvolveMatrix.

Returns None when:

• columns * rows != data.len()
• target_x >= columns
• target_y >= rows

pub fn target_x(&self) -> u32

Returns a matrix’s X target.

targetX in the SVG.

pub fn target_y(&self) -> u32

Returns a matrix’s Y target.

targetY in the SVG.

pub fn columns(&self) -> u32

Returns a number of columns in the matrix.

Part of the order attribute in the SVG.

pub fn rows(&self) -> u32

Returns a number of rows in the matrix.

Part of the order attribute in the SVG.

pub fn get(&self, x: u32, y: u32) -> f64

Returns a matrix value at the specified position.

Panics

• When position is out of bounds.

pub fn data(&self) -> &[f64]

Returns a reference to an internal data.
