(Sorry to be pain)
Constructing a Resizer using Type::Point causes a panics. The data type seems to be irrelevant.
let resizer = resize::new(10, 10, 5, 5, resize::Pixel::RGBF64, resize::Type::Point);thread 'main' panicked at 'attempt to subtract with overflow', /home/surma/.cargo/registry/src/github.com-1ecc6299db9ec823/resize-0.5.2/src/lib.rs:276:24
Full backtrace:
warning: unused variable: `resizer`
