Struct ffimage::packed::dynamic::ImageBuffer

pub struct ImageBuffer { /* fields omitted */ }

Image buffer parametrized by its pixel type

Implementations

impl ImageBuffer

pub fn empty(typ: StorageType) -> Self

Returns an empty image buffer

Arguments

• typ - Storage type

Example

use ffimage::packed::dynamic::{ImageBuffer, StorageType};

let buf = ImageBuffer::empty(StorageType::U8);

pub fn new(width: u32, height: u32, channels: u32, typ: StorageType) -> Self

Returns an image buffer with unknown pixel type

Arguments

• width - Width in pixels
• height - Height in pixels
• channels - Number of channels
• typ - Storage type

Example

use ffimage::packed::dynamic::{ImageBuffer, StorageType};

let buf = ImageBuffer::new(2, 2, 3, StorageType::U8);

pub fn from_raw<T: 'static>(
    width: u32,
    height: u32,
    raw: Vec<T>
) -> Option<Self>

Returns an image buffer with unknown pixel type

Arguments

• width - Width in pixels
• height - Height in pixels
• typ - Storage type
• raw - Raw memory region owned by the instance

Example

use ffimage::packed::dynamic::ImageBuffer;

let mem: Vec<u8> = vec![0; 12];
let buf = ImageBuffer::from_raw(2, 2, mem);

pub fn raw(&self) -> &MemoryBuffer

Returns the raw memory

pub fn raw_mut(&mut self) -> &mut MemoryBuffer

Returns the raw memory

pub fn width(&self) -> u32

Returns the width in pixels

pub fn height(&self) -> u32

Returns the height in pixels

pub fn stride(&self) -> usize

Returns the length of one image row in bytes

pub fn resize(&mut self, width: u32, height: u32, channels: u32)

pub fn as_view(&self) -> ImageView

Trait Implementations

impl<'a, '_> From<&'_ ImageView<'a>> for ImageBuffer

fn from(input: &ImageView<'a>) -> Self

Performs the conversion.
