Struct exif::Exif

source ·
pub struct Exif { /* private fields */ }
Expand description

A struct that holds the parsed Exif attributes.

§Examples

// Get a specific field.
let xres = exif.get_field(Tag::XResolution, In::PRIMARY)?;
assert_eq!(xres.display_value().with_unit(&exif).to_string(),
           "72 pixels per inch");
// Iterate over all fields.
for f in exif.fields() {
    println!("{} {} {}", f.tag, f.ifd_num, f.display_value());
}

Implementations§

source§

impl Exif

source

pub fn buf(&self) -> &[u8]

Returns the slice that contains the TIFF data.

source

pub fn fields(&self) -> impl ExactSizeIterator<Item = &Field>

Returns an iterator of Exif fields.

source

pub fn little_endian(&self) -> bool

Returns true if the Exif data (TIFF structure) is in the little-endian byte order.

source

pub fn get_field(&self, tag: Tag, ifd_num: In) -> Option<&Field>

Returns a reference to the Exif field specified by the tag and the IFD number.
