Struct gift::Encoder

pub struct Encoder<W: Write> { /* private fields */ }

GIF file encoder

Can be converted to one of three encoders:

• into_step_enc for high-level Steps
• into_frame_enc for mid-level Frames
• into_block_enc for low-level Blocks

Encoding Example

use gift::{Encoder, Step};
use pix::{gray::Gray8, Palette, Raster, rgb::SRgb8};
use std::error::Error;
use std::io::Write;

fn encode<W: Write>(mut w: W) -> Result<(), Box<dyn Error>> {
    let mut enc = Encoder::new(&mut w).into_step_enc();
    let mut raster = Raster::with_clear(4, 4);
    *raster.pixel_mut(0, 0) = Gray8::new(1);
    *raster.pixel_mut(1, 1) = Gray8::new(1);
    *raster.pixel_mut(2, 2) = Gray8::new(1);
    *raster.pixel_mut(3, 3) = Gray8::new(1);
    let mut palette = Palette::new(2);
    palette.set_entry(SRgb8::new(0xFF, 0, 0));
    palette.set_entry(SRgb8::new(0xFF, 0xFF, 0));
    let step = Step::with_indexed(raster, palette);
    enc.encode_step(&step)?;
    Ok(())
}
