[−][src]Struct rin::graphics::image::pnm::PNMHeader
Stores the complete header data of a file.
Internally, provides mechanisms for lossless reencoding. After reading a file with the decoder it is possible to recover the header and construct an encoder. Using the encoder on the just loaded image should result in a byte copy of the original file (for single image pnms without additional trailing data).
Methods
impl PNMHeader[src]
impl PNMHeaderpub fn subtype(&self) -> PNMSubtype[src]
pub fn subtype(&self) -> PNMSubtypeRetrieve the format subtype from which the header was created.
pub fn width(&self) -> u32[src]
pub fn width(&self) -> u32The width of the image this header is for.
pub fn height(&self) -> u32[src]
pub fn height(&self) -> u32The height of the image this header is for.
pub fn maximal_sample(&self) -> u32[src]
pub fn maximal_sample(&self) -> u32The biggest value a sample can have. In other words, the colour resolution.
pub fn as_bitmap(&self) -> Option<&BitmapHeader>[src]
pub fn as_bitmap(&self) -> Option<&BitmapHeader>Retrieve the underlying bitmap header if any
pub fn as_graymap(&self) -> Option<&GraymapHeader>[src]
pub fn as_graymap(&self) -> Option<&GraymapHeader>Retrieve the underlying graymap header if any
pub fn as_pixmap(&self) -> Option<&PixmapHeader>[src]
pub fn as_pixmap(&self) -> Option<&PixmapHeader>Retrieve the underlying pixmap header if any
pub fn as_arbitrary(&self) -> Option<&ArbitraryHeader>[src]
pub fn as_arbitrary(&self) -> Option<&ArbitraryHeader>Retrieve the underlying arbitrary header if any
pub fn write(&self, writer: &mut dyn Write) -> Result<(), Error>[src]
pub fn write(&self, writer: &mut dyn Write) -> Result<(), Error>Write the header back into a binary stream
