Struct PixelConverter

pub(crate) struct PixelConverter {
    memory_limit: MemoryLimit,
    color_output: ColorOutput,
    buffer: Vec<u8>,
    global_palette: Option<Vec<u8>>,
}

Deinterlaces and expands to RGBA if needed

Fields

memory_limit: MemoryLimit

color_output: ColorOutput

buffer: Vec<u8>

global_palette: Option<Vec<u8>>

Implementations

impl PixelConverter

pub(crate) const fn new( color_output: ColorOutput, memory_limit: MemoryLimit, ) -> Self

pub(crate) fn check_buffer_size( &self, frame: &Frame<'_>, ) -> Result<usize, DecodingError>

pub(crate) fn read_frame( &mut self, frame: &mut Frame<'_>, data_callback: &'_ mut dyn FnMut(&mut OutputBuffer<'_>) -> Result<usize, DecodingError>, ) -> Result<(), DecodingError>

pub(crate) const fn buffer_size(&self, frame: &Frame<'_>) -> Option<usize>

pub(crate) const fn line_length(&self, frame: &Frame<'_>) -> usize

pub(crate) fn fill_buffer( &mut self, current_frame: &Frame<'_>, buf: &mut [u8], data_callback: &'_ mut dyn FnMut(&mut OutputBuffer<'_>) -> Result<usize, DecodingError>, ) -> Result<bool, DecodingError>

Use read_into_buffer to deinterlace

pub(crate) fn global_palette(&self) -> Option<&[u8]>

pub(crate) fn set_global_palette(&mut self, palette: Vec<u8>)

pub(crate) fn read_into_buffer( &mut self, frame: &Frame<'_>, buf: &mut [u8], data_callback: &'_ mut dyn FnMut(&mut OutputBuffer<'_>) -> Result<usize, DecodingError>, ) -> Result<(), DecodingError>

Applies deinterlacing

Set frame.interlaced = false afterwards if you’re putting the buffer back into the Frame
