Struct jpegxl_rs::decode::JxlDecoder [−][src]
JPEG XL Decoder
Implementations
impl<'a> JxlDecoder<'a>[src]
pub fn set_num_channels(&mut self, value: u32)[src]
Set number of channels
pub fn set_endianness(&mut self, value: Endianness)[src]
Set pixel endianness
pub fn set_align(&mut self, value: usize)[src]
Set pixel scanlines alignment
pub fn keep_orientation(&mut self, value: bool)[src]
Keep original orientation or not. Default: false
Note: Set true could make decoding faster, but you need to manually transform the result with the correct
orientation.
pub fn decode<T: PixelType>(
&self,
data: &[u8]
) -> Result<DecoderResult<T>, DecodeError>[src]
&self,
data: &[u8]
) -> Result<DecoderResult<T>, DecodeError>
Decode a JPEG XL image
Currently only support RGB(A)8/16/32 encoded static image. Other info are discarded.
Errors
Return a DecodeError when internal decoder fails
Panics
Only when underlying library events order is wrong
pub fn decode_jpeg(&self, data: &[u8]) -> Result<DecoderResult<u8>, DecodeError>[src]
Decode a JPEG XL image and reconstruct JPEG data
Currently only support RGB(A)8/16/32 encoded static image. Other info are discarded.
Errors
Return a DecodeError when internal decoder fails
Panics
Only when underlying library events order is wrong
