Struct ratatu_image::picker::Picker

pub struct Picker { /* private fields */ }

Implementations

impl Picker

Helper for building widgets

pub fn new( font_size: FontSize, backend_type: BackendType, background_color: Option<Rgb<u8>> ) -> Result<Picker, Box<dyn Error>>

Create a picker from a given terminal FontSize.

Example

use std::io;
use ratatu_image::{
    picker::{BackendType, Picker},
    Resize,
};
use ratatui::{
    backend::{Backend, TestBackend},
    layout::Rect,
    Terminal,
};

let dyn_img = image::io::Reader::open("./assets/Ada.png").unwrap().decode().unwrap();
let mut picker = Picker::new(
    (7, 14),
    BackendType::Halfblocks,
    None,
).unwrap();

// For FixedImage:
let image_static = picker.new_static_fit(
    dyn_img,
    Rect::new(0, 0, 15, 5),
    Resize::Fit,
).unwrap();
// For ResizeImage:
let image_fit_state = picker.new_state();

pub fn set(&mut self, type: BackendType)

Set a specific backend

pub fn cycle_backends(&mut self) -> BackendType

Cycle through available backends

pub fn new_static_fit( &mut self, image: DynamicImage, size: Rect, resize: Resize ) -> Result<Box<dyn FixedBackend>, Box<dyn Error>>

Returns a new static backend for crate::FixedImage widgets that fits into the given size.

pub fn new_state(&mut self) -> Box<dyn ResizeBackend>

Returns a new state backend for crate::ResizeImage.

pub fn backend_type(&self) -> &BackendType

pub fn font_size(&self) -> FontSize
