Struct PreloadedImageData 

pub struct PreloadedImageData {
    pub data: Cow<'static, [u8]>,
    pub width: u32,
    pub height: u32,
    pub id: String,
}

Preloaded decoded raster image data

Fields

data: Cow<'static, [u8]>

The decoded image data in RGBA format with blended semi trsparent color. Make sure that if you submit the data directly it must be blended for semi transparent colors. Either a static slice or an owned vector. Povide a static slice that is pre-blended in case of static resource linking for rendering.

width: u32

The width of image in pixels

height: u32

The height of image in pixels

id: String

Original id used to resolve the image

Implementations

impl PreloadedImageData

pub fn blend_rgba_slice(rgba_slice: &[u8]) -> Vec<u8>

Converts raw rgba pixmap source to the rgba source with blended semi transparent colors.

pub fn new(id: String, width: u32, height: u32, rgba_data: &[u8]) -> Self

Creates a new PreloadedImageData from the given rgba8 buffer and blends all the semi transparent colors.

pub fn new_blended( id: String, width: u32, height: u32, rgba_data: &'static [u8], ) -> Self

Creates a new PreloadedImageData from the given rgba8 buffer which is meant to be already blended for semi transparent colors.

You can use PreloadedImageData::blend_rgba_slice to blend the colors in advance.

Trait Implementations

impl Debug for PreloadedImageData

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

Formats the value using the given formatter.

impl Display for PreloadedImageData

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

Formats the value using the given formatter.

impl PartialEq for PreloadedImageData

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