Struct Image 

Source
pub struct Image {
    pub bytes: Arc<[u8]>,
    pub format: ImageFormat,
    pub width_px: u32,
    pub height_px: u32,
    pub components: u8,
    pub common: Common,
}
Expand description

A validated, embeddable JPEG or PNG. bytes are the original file bytes, kept as-is — pixel decoding (only ever needed for PNG, to split out the alpha channel as a SMask) happens later, in the facade.

Fields§

§bytes: Arc<[u8]>§format: ImageFormat§width_px: u32§height_px: u32§components: u8

1 = Gray, 3 = RGB, 4 = RGBA (JPEG is always 1 or 3, never 4).

§common: Common

Implementations§

Source§

impl Image

Source

pub fn new(bytes: impl Into<Arc<[u8]>>) -> Result<Image, ImageError>

Validates bytes as a supported JPEG or PNG and extracts the metadata layout needs (dimensions, color components). Rejects anything outside V1’s explicit scope instead of a silent best-effort attempt (phases/phase-5-images.md step 2-3).

Source

pub fn width(self, width: f32) -> Image

Source

pub fn height(self, height: f32) -> Image

Source

pub fn flex(self, factor: f32) -> Image

Source

pub fn keep_with_next(self) -> Image
