Struct fltk::image::RgbImage

pub struct RgbImage { /* fields omitted */ }

Creates a struct holding a raw RGB image

Implementations

impl RgbImage

pub fn new(
    data: &[u8],
    w: u32,
    h: u32,
    depth: u32
) -> Result<RgbImage, FltkError>

Initializes a new raw RgbImage, gives the slice static lifetime If you need to work with RGB data, it's suggested to use the Image crate https://crates.io/crates/image

pub unsafe fn into_parts(self) -> (Vec<u8>, u32, u32)

Deconstructs a raw RgbImage into parts

Safety

Destructures the image into its raw elements
