JPEG XL Decoder

Fields

basic_info: Option<JxlBasicInfo>

Basic info about the image. None if it have not read the head.

pixel_format: JxlPixelFormat

Pixel format

Implementations

impl<T: PixelType> JxlDecoder<T>

pub fn new(
    memory_manager: Option<&JxlMemoryManagerStruct>,
    parallel_runner: Option<&mut impl JXLParallelRunner>
) -> Result<Self, JxlError>

Create a decoder.
Memory manager and Parallel runner API are WIP.

pub fn default() -> Result<Self, JxlError>

Create a decoder with default settings,

pub fn decode(
    &mut self,
    data: &[u8]
) -> Result<(JxlBasicInfo, Vec<T>), JxlError>

Decode a JPEG XL image.
Currently only support RGB(A)8/16/32 encoded static image. Color info and transformation info are discarded.

Example

let sample = std::fs::read("test/sample.jxl")?;
let mut decoder: JxlDecoder<u8> = JxlDecoder::default()?;
let (info, buffer) = decoder.decode(&sample)?;

Trait Implementations

impl<T: PixelType> Drop for JxlDecoder<T>

pub fn drop(&mut self)

Executes the destructor for this type.
