[−][src]Struct exif::Exif

pub struct Exif { /* fields omitted */ }

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

impl Exif[src]

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

Returns the slice that contains the TIFF data.

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

Returns an iterator of Exif fields.

pub fn little_endian(&self) -> bool[src]

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

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

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