bmp-monochrome
Encode and decode monochromatic bitmaps without additional dependencies, useful for QR codes.
Example
```rust
use bmp_monochrome::Bmp;
use std::error::Error;
use std::fs::File;
fn main() -> Result<(), Box> {
let filename = "test.bmp";
let width = 21;
let data: Vec = (0..width * width).map(|e| e % 2 == 0).collect();
let rows: Vec> = data.chunks(width).map(|e| e.tovec()).collect();
let bmp = Bmp::new(rows)?;
bmp.write(File::create(filename)?)?;
let bmpread = Bmp::read(File::open(filename)?)?;
asserteq!(bmp, bmp_read);
Ok(())
}
```
