Struct FrameDecoder
pub struct FrameDecoder { /* private fields */ }Decoder for Frame::make_lzw_pre_encoded
Implementations
impl FrameDecoder
fn new(options: DecodeOptions) -> SelfSee also
set_global_palettefn set_global_palette(&mut self, palette: Vec<u8>)Palette used for RGBA conversion
fn decode_lzw_encoded_frame(&mut self, frame: &mut Frame<'_>) -> Result<(), DecodingError>Converts the frame in-place, replacing its LZW buffer with pixels.
If you get an error about invalid min code size, the buffer was probably pixels, not compressed data.
fn decode_lzw_encoded_frame_into_buffer(&mut self, frame: &Frame<'_>, buf: &mut [u8]) -> Result<(), DecodingError>Converts into the given buffer. It must be [
buffer_size()] bytes large.Pixels are always deinterlaced, so update
frame.interlacedafterwards if you're putting the buffer back into the frame.fn buffer_size(&self, frame: &Frame<'_>) -> usizeNumber of bytes required for
