Struct usvg_tree::filter::ConvolveMatrixData

pub struct ConvolveMatrixData {
    pub target_x: u32,
    pub target_y: u32,
    pub columns: u32,
    pub rows: u32,
    pub data: Vec<f32>,
}

A convolve matrix representation.

Used primarily by ConvolveMatrix.

Fields

target_x: u32

Returns a matrix’s X target.

targetX in the SVG.

target_y: u32

Returns a matrix’s Y target.

targetY in the SVG.

columns: u32

Returns a number of columns in the matrix.

Part of the order attribute in the SVG.

rows: u32

Returns a number of rows in the matrix.

Part of the order attribute in the SVG.

data: Vec<f32>

The actual matrix.

Implementations

impl ConvolveMatrixData

pub fn new( target_x: u32, target_y: u32, columns: u32, rows: u32, data: Vec<f32> ) -> Option<Self>

Creates a new ConvolveMatrixData.

Returns None when:

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

pub fn get(&self, x: u32, y: u32) -> f32

Returns a matrix value at the specified position.

Panics

• When position is out of bounds.
