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: i32,
    h: i32,
    depth: ColorDepth
) -> Result<RgbImage, FltkError>

Initializes a new raw RgbImage, copies the data and handles its lifetime. If you need to work with RGB data,

Errors

Errors on invalid or unsupported image format

pub unsafe fn from_data(
    data: &[u8],
    w: i32,
    h: i32,
    depth: ColorDepth
) -> Result<RgbImage, FltkError>

Initializes a new raw RgbImage from shared data, doesn’t handle the data’s lifetime

Safety

The data must be valid for the lifetime of the image

Errors

Errors on invalid or unsupported image format

pub unsafe fn new2(
    data: &[u8],
    w: i32,
    h: i32,
    depth: i32,
    line_data: i32
) -> Result<RgbImage, FltkError>

Initializes a new raw RgbImage, copies the data and handles its lifetime. If you need to work with RGB data,

Errors

Errors on invalid or unsupported image format

Safety

Passing wrong line data can read to over or underflow

pub unsafe fn from_data2(
    data: &[u8],
    w: i32,
    h: i32,
    depth: i32,
    line_data: i32
) -> Result<RgbImage, FltkError>

Initializes a new raw RgbImage from shared data, doesn’t handle the data’s lifetime

Safety

The data must be valid for the lifetime of the image

Errors

Errors on invalid or unsupported image format

Safety

Passing wrong line data can read to over or underflow

pub unsafe fn into_parts(self) -> (Vec<u8>, i32, i32)

Deconstructs a raw RgbImage into parts

Safety

Destructures the image into its raw elements
