Struct PatternImage 

pub struct PatternImage(/* private fields */);

Shared image sampling contract captured by a paint, independent of content decoders.

Implementations

impl PatternImage

pub fn width(&self) -> u32

Base mip width in pixels.

pub fn height(&self) -> u32

Base mip height in pixels.

pub fn levels(&self) -> usize

Number of retained mip levels, including the base image.

pub fn size(&self, level: usize) -> (u32, u32)

Width and height of a valid retained mip level.

pub fn texel(&self, level: usize, column: usize, row: usize) -> [f32; 4]

Reads a linear-premultiplied texel; level and pixel indices must be valid.

pub fn extend_level(&self, level: usize, out: &mut Vec<f32>)

Appends a whole level in row-major order, four f32 per texel.
