Simple tool to measure time of opening of image files.
Compile app
cargo build
cargo build --release
and get binary from target folder:
target/debug/image_opening /home/rafal/photos
target/release/image_opening /home/rafal/photos2
Current(0.23) image crate open images very slowly(Just opening with image::open() without any computations)
| Photo | Size | Dimension | Debug opening time | Release opening time |
|---|---|---|---|---|
| PNG | 4,3MB | 3840x2592 | 9461ms | 191ms |
| PNG | 191,5kB | 493x333 | 174ms | 4ms |
