Provided Methods

fn read_magic_constant(&mut self) -> ImageResult<[u8; 2]>

Reads the two magic constant bytes

fn read_next_string(&mut self) -> ImageResult<String>

Reads a string as well as a single whitespace after it, ignoring comments

fn read_next_u32(&mut self) -> ImageResult<u32>

fn read_bitmap_header( &mut self, encoding: SampleEncoding, ) -> ImageResult<BitmapHeader>

fn read_graymap_header( &mut self, encoding: SampleEncoding, ) -> ImageResult<GraymapHeader>

fn read_pixmap_header( &mut self, encoding: SampleEncoding, ) -> ImageResult<PixmapHeader>

fn read_arbitrary_header(&mut self) -> ImageResult<ArbitraryHeader>
