Struct Png 

pub struct Png;

PNG read for its pixels (png, .png), with the png feature. Its size is checked first, as PngInfo does, so a picture too big is refused before its pixels are decoded.

Trait Implementations

impl Clone for Png

fn clone(&self) -> Png

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Png

impl Debug for Png

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Png

fn default() -> Png

Returns the “default value” for a type.

impl Eq for Png

impl Format for Png

Available on crate feature png only.

type Asset = Image

The kind it reads.

fn id(&self) -> &'static str

Stable id, e.g. "png", "tiled-tmx", "yarn": one per format of a kind.

fn extensions(&self) -> &'static [&'static str]

File extensions this format claims, lowercase, without the dot. A format that only stands in another’s place (a one-bit picture at a PNG’s path) claims none and is found by sniff.

fn sniff(&self, bytes: &[u8]) -> bool

True if these bytes look like this format (magic bytes); false when the format has none.

fn max_bytes(&self) -> usize

The most bytes it reads: a bigger file is refused before decode sees it. DEFAULT_MAX_BYTES unless the format says.

fn decode( &self, file: &AssetPath, bytes: &[u8], _cx: &DecodeCx<'_>, ) -> Result<Image, Vec<ContentError>>

Every problem found, each with file and place; never a panic.

impl PartialEq for Png

fn eq(&self, other: &Png) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
