Enum PixelFormat

pub enum PixelFormat {
    RGBA,
    RGB,
    GrayAlpha,
    Gray,
    Alpha,
    PNG,
}

Formats for storing pixel data in an image.

This type determines how the raw data array of an Image is to be interpreted.

Regardless of format, pixel data for an image is always stored one complete pixel at a time, in row-major order (that is, the top-left pixel comes first, followed by the rest of the top row from left to right; then comes the second row down, again from left to right, and so on until finally the bottom-right pixel comes last).

Variants

RGBA

32-bit color with alpha channel. Each pixel is four bytes, with red first and alpha last.

RGB

24-bit color with no alpha. Each pixel is three bytes, with red first and blue last.

GrayAlpha

16-bit grayscale-with-alpha. Each pixel is two bytes, with the grayscale value first and alpha second.

Gray

8-bit grayscale with no alpha. Each pixel is one byte (0=black, 255=white).

Alpha

8-bit alpha mask with no color. Each pixel is one byte (0=transparent, 255=opaque).

PNG

PNG data.

Implementations

impl PixelFormat

pub fn bits_per_pixel(self) -> u32

Returns the number of bits needed to store a single pixel in this format.

Trait Implementations

impl Clone for PixelFormat

fn clone(&self) -> PixelFormat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PixelFormat

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

Formats the value using the given formatter.

impl Hash for PixelFormat

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 PartialEq for PixelFormat

fn eq(&self, other: &PixelFormat) -> 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.
