Struct show_image::ImageInfo

pub struct ImageInfo {
    pub pixel_format: PixelFormat,
    pub width: u32,
    pub height: u32,
    pub stride_x: u32,
    pub stride_y: u32,
}

Information describing the binary data of an image.

Fields

pixel_format: PixelFormat

The pixel format of the image data.

width: u32

The width of the image in pixels.

height: u32

The height of the image in pixels.

stride_x: u32

The X stride of the image data in bytes.

stride_y: u32

The Y stride of the image data in bytes.

Implementations

impl ImageInfo

pub fn new(pixel_format: PixelFormat, width: u32, height: u32) -> Self

Create a new info struct with the given format, width and height.

The row stride is automatically calculated based on the image width and pixel format. If you wish to use a different row stride, construct the struct directly.

pub fn mono8(width: u32, height: u32) -> Self

Create a new info struct for an 8-bit monochrome image with the given width and height.

pub fn mono_alpha8(width: u32, height: u32) -> Self

Create a new info struct for an 8-bit monochrome image with with alpha channel and the given width and height.

pub fn mono_alpha8_premultiplied(width: u32, height: u32) -> Self

Create a new info struct for an 8-bit monochrome image with premultiplied alpha channel and the given width and height.

pub fn bgr8(width: u32, height: u32) -> Self

Create a new info struct for an 8-bit BGR image with the given width and height.

pub fn bgra8(width: u32, height: u32) -> Self

Create a new info struct for an 8-bit BGRA image with the given width and height.

pub fn bgra8_premultiplied(width: u32, height: u32) -> Self

Create a new info struct for an 8-bit BGRA image with premultiplied alpha channel and the given width and height.

pub fn rgb8(width: u32, height: u32) -> Self

Create a new info struct for an 8-bit RGB image with the given width and height.

pub fn rgba8(width: u32, height: u32) -> Self

Create a new info struct for an 8-bit RGBA image with the given width and height.

pub fn rgba8_premultiplied(width: u32, height: u32) -> Self

Create a new info struct for an 8-bit RGBA image with premultiplied alpha channel and the given width and height.

pub fn byte_size(self) -> u64

Get the image size in bytes.
