# imghdr
|
||||
|

Library that determines the type of image contained in a file or byte stream, basically clone of the Python [imghdr](docs.python.org/library/imghdr.html) module.

## Examples
|
||||
|

Check a file directly:
|
||||
|
||||
```rust
|
||||
extern crate imghdr;
|
||||
|
||||
fn main() {
|
||||
match imghdr::open("/path/to/image.png") {
|
||||
Ok(imghdr::Type::Png) => println!("Yep, it is a PNG"),
|
||||
_ => println!("Nope, it is definitely not a PNG"),
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Or check a byte stream:
|
||||
|
||||
```rust
|
||||
extern crate imghdr;
|
||||
|
||||
fn main() {
|
||||
let mut file = File::open("/path/to/image.png").unwrap();
|
||||
let mut content: Vec<u8> = vec![];
|
||||
file.read_to_end(&mut content).unwrap();
|
||||
|
||||
match imghdr::what(content.as_slice()) {
|
||||
Some(imghdr::Type::Jpg) => println!("And this is a Jpeg"),
|
||||
_ => println!("Can a Png, Bmp or other file format"),
|

}

To sing a song that old was sung,
|
||||
From ashes ancient Gower is come;
|
||||
Assuming man's infirmities,
|
||||
To glad your ear, and please your eyes.
|
||||
It hath been sung at festivals,
|
||||
On ember-eves and holy-ales;
|
||||
And lords and ladies in their lives
|
||||
Have read it for restoratives:
|
||||
The purchase is to make men glorious;
|
||||
Et bonum quo antiquius, eo melius.
|
||||
If you, born in these latter times,
|
||||
When wit's more ripe, accept my rhymes.
|
||||
And that to hear an old man sing
|
||||
May to your wishes pleasure bring
|
||||
I life would wish, and that I might
|
||||
Waste it for you, like taper-light.
|
||||
This Antioch, then, Antiochus the Great
|
||||
Built up, this city, for his chiefest seat:
|
||||
The fairest in all Syria,
|
||||
I tell you what mine authors say:
|
||||
This king unto him took a fere,
|
||||
Who died and left a female heir,
|
||||
So buxom, blithe, and full of face,
|
||||
As heaven had lent her all his grace;
|
||||
With whom the father liking took,
|
||||
And her to incest did provoke:
|
||||
Bad child; worse father! to entice his own
|
||||
To evil should be done by none:
|
||||
But custom what they did begin
|
||||
Was with long use account no sin.
|
||||
The beauty of this sinful dame
|
||||
Made many princes thither frame,
|
||||
To seek her as a bed-fellow,
|
||||
In marriage-pleasures play-fellow:
|
||||
Which to prevent he made a law,
|
||||
To keep her still, and men in awe,
|
||||
That whoso ask'd her for his wife,
|
||||
His riddle told not, lost his life:
|
||||
So for her many a wight did die,
|
||||
As yon grim looks do testify.
|
||||
What now ensues, to the judgment of your eye
|
||||
I give, my cause who best can justify.
