Struct romy::Image

pub struct Image { /* fields omitted */ }

An image that can be displayed by the runtime.

Internally stores data as an array of 32 bit RGBA values.

Methods

impl Image

pub fn new(width: i32, height: i32, color: Color) -> Image

Create a blank image

Arguments

• width - the number of horizontal pixels
• height - the number of vertical pixels.
• color - the initial color of all pixels in the image.

pub fn from_data(width: i32, height: i32, data: &[u8]) -> Image

Create an image from a slice of existing data

Arguments

• width - the number of horizontal pixels
• height - the number of vertical pixels
• data - slice of existing data.

pub fn get_pixel(&self, x: i32, y: i32) -> Color

Gets a pixel in the image

Arguments

• x - horizontal coordinate
• y - vertical coordinate

pub fn set_pixel(&mut self, x: i32, y: i32, color: Color)

Sets a pixel in the image to a specified color

Arguments

• x - horizontal coordinate
• y - vertical coordinate
• color - color to set the pixel to

pub fn width(&self) -> i32

Gets the number of horizontal pixels

pub fn height(&self) -> i32

Gets the number of vertical pixels

pub fn pixels(&self) -> &[u32]

Gets a reference to the raw pixel buffer

pub fn pixels8(&self) -> &[u8]

Gets a reference to the raw pixel as u8s

pub fn pixels_mut(&mut self) -> &mut [u32]

Gets a mutable reference to the raw pixel buffer

pub fn pixels8_mut(&mut self) -> &mut [u8]

Gets a mutable reference to the raw pixel buffer as u8s
