Struct Header 

pub struct Header {
    pub file_size: u32,
    pub image_data_start: usize,
    pub image_size: Size,
    pub bpp: Bpp,
    pub image_data_len: u32,
    pub channel_masks: Option<ChannelMasks>,
    pub row_order: RowOrder,
    pub compression_method: CompressionMethod,
}

BMP header information.

The header can be accessed by using RawBmp::header.

Fields

file_size: u32

Total file size in bytes.

image_data_start: usize

Byte offset from beginning of file at which pixel data begins.

image_size: Size

Image size in pixels.

bpp: Bpp

Number of bits per pixel.

image_data_len: u32

Length in bytes of the image data.

channel_masks: Option<ChannelMasks>

Bit masks for the color channels.

row_order: RowOrder

Row order of the image data within the file

compression_method: CompressionMethod

The compression method

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Header

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Header

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Header

fn cmp(&self, other: &Header) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Header

fn eq(&self, other: &Header) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Header

fn partial_cmp(&self, other: &Header) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
