Struct UninitializedJxlImage

pub struct UninitializedJxlImage { /* private fields */ }

Empty, uninitialized JPEG XL image.

Examples

let mut uninit_image = JxlImage::builder().build_uninit();
let image = loop {
    let buf = read_bytes()?;
    uninit_image.feed_bytes(buf)?;
    match uninit_image.try_init()? {
        InitializeResult::NeedMoreData(uninit) => {
            uninit_image = uninit;
        }
        InitializeResult::Initialized(image) => {
            break image;
        }
    }
};
println!("{:?}", image.image_header());

Implementations

impl UninitializedJxlImage

pub fn feed_bytes(&mut self, buf: &[u8]) -> Result<()>

Feeds more data into the decoder.

pub fn reader(&self) -> &ContainerDetectingReader

Returns the internal reader.

pub fn try_init(self) -> Result<InitializeResult>

Try to initialize an image with the data fed into so far.

Returns

• Ok(InitializeResult::Initialized(_)) if the initialization was successful,
• Ok(InitializeResult::NeedMoreData(_)) if the data was not enough, and
• Err(_) if there was a decode error during the initialization, meaning invalid bitstream was given.
