Trait Implementations

impl<R: BufRead> ImageDecoder for HDRAdapter<R>

fn dimensions(&mut self) -> ImageResult<(u32, u32)>

Returns a tuple containing the width and height of the image

fn colortype(&mut self) -> ImageResult<ColorType>

Returns the color type of the image e.g. RGB(8) (8bit RGB)

fn row_len(&mut self) -> ImageResult<usize>

Returns the length in bytes of one decoded row of the image

fn read_scanline(&mut self, _: &mut [u8]) -> ImageResult<u32>

Reads one row from the image into buf and returns the row index

fn read_image(&mut self) -> ImageResult<DecodingResult>

Decodes the entire image and return it as a Vector

fn is_animated(&mut self) -> ImageResult<bool>

Returns true if the image is animated

fn into_frames(self) -> ImageResult<Frames>

Returns the frames of the image

fn load_rect(
    &mut self,
    x: u32,
    y: u32,
    length: u32,
    width: u32
) -> ImageResult<Vec<u8>>

Decodes a specific region of the image, represented by the rectangle starting from x and y and having length and width
