imageinfo-rs

Rust library to get image size and format without loading/decoding.

The imageinfo don't get image format by file ext name, but infer by file header bytes and character.

A rewrite of c++ version imageinfo

Some test image files are from image-size. Many thanks to @netroy.

Example

use imageinfo::{ImageInfo};

fn main() {
    match ImageInfo::from_file_path("images/valid/bmp/sample.bmp") {
        Ok(info) => {
            println!("  - Ext       : {}", info.ext);
            println!("  - Full Ext  : {}", info.full_ext);
            println!("  - Size      : {}", info.size);
            println!("  - Mimetype  : {}", info.mimetype);
            println!("  - Entries   :");
            for size in info.entry_sizes.iter() {
                println!("    - {}", size);
            }
        }
        Err(err) => {
            println!("  - Err       : {}", err);
        }
    }
}

Pretty easy?

Don't be stingy with your star : )
