Implementations

impl ConvolveMatrixData

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 data(&self) -> &[f32]

The actual matrix.

impl ConvolveMatrixData

pub(crate) 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.
