Struct jpegxl_rs::JpegxlDecoder

pub struct JpegxlDecoder {
    pub basic_info: Option<JpegxlBasicInfo>,
    // some fields omitted
}

JPEG XL Decoder

Fields

basic_info: Option<JpegxlBasicInfo>

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

Implementations

impl JpegxlDecoder

pub fn new(
    memory_manager: Option<JpegxlMemoryManager>,
    parallel_runner: Option<ParallelRunner>
) -> Option<Self>

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

pub fn new_with_default() -> Option<Self>

Create a decoder with default settings, e.g. with default memory allocator and single-threaded.

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

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

Example

let sample = std::fs::read("test/sample.jxl")?;
let mut decoder = JpegxlDecoder::new_with_default().ok_or(JpegxlError::CannotCreateDecoder)?;
let buffer = decoder.decode(&sample)?;
