Struct HalfBlockImage 

pub struct HalfBlockImage {
    pub width: u32,
    pub height: u32,
    pub pixels: Vec<(Color, Color)>,
}

A terminal-renderable image stored as a grid of Color values.

Each cell contains a foreground color (upper pixel) and background color (lower pixel), rendered using the ▀ half-block character.

Create from an image::DynamicImage with HalfBlockImage::from_dynamic (requires image feature), or construct manually from raw RGB data with HalfBlockImage::from_rgb.

Fields

width: u32

Width in terminal columns.

height: u32

Height in terminal rows (each row = 2 image pixels).

pixels: Vec<(Color, Color)>

Row-major pairs of (upper_color, lower_color) for each cell.

Implementations

impl HalfBlockImage

pub fn from_dynamic(img: &DynamicImage, width: u32, height: u32) -> Self

Create a half-block image from a DynamicImage, resized to fit the given terminal cell dimensions.

The image is resized to width x (height * 2) pixels using Lanczos3 filtering, then each pair of vertically adjacent pixels is packed into one terminal cell.

impl HalfBlockImage

pub fn from_rgb(rgb_data: &[u8], width: u32, height: u32) -> Self

Create a half-block image from raw RGB pixel data.

rgb_data must contain width x pixel_height x 3 bytes in row-major RGB order, where pixel_height = height * 2.
