Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

width: u32

Image width in pixels.

height: u32

Image height in pixels.

channels: u16

Number of channels per pixel in the source.

bit_depth: u8

Bits per channel in the source.

color_type: ColorType

Source color type from the TIFF decoder.

is_float: bool

Whether the source uses floating-point samples.

is_signed: bool

Whether the source uses signed integer samples.

icc_profile: Option<Vec<u8>>

ICC color profile (Tag 34675).

exif: Option<Vec<u8>>

Raw EXIF sub-IFD bytes, re-serialized from the EXIF IFD (Tag 34665 pointer).

xmp: Option<Vec<u8>>

XMP metadata (Tag 700).

iptc: Option<Vec<u8>>

IPTC-NAA metadata (Tag 33723).

resolution_unit: Option<u16>

Resolution unit (Tag 296): 1 = no unit, 2 = inch, 3 = centimeter.

x_resolution: Option<(u32, u32)>

X resolution as a rational (numerator, denominator) (Tag 282).

y_resolution: Option<(u32, u32)>

Y resolution as a rational (numerator, denominator) (Tag 283).

dpi: Option<(f64, f64)>

DPI computed from resolution tags. Both values are in dots-per-inch (centimeter resolution is converted). None if resolution unit is absent or “no unit” (1).

orientation: Option<u16>

EXIF orientation (Tag 274): values 1-8. None if not present.

compression: Option<u16>

Compression method (Tag 259).

photometric: Option<u16>

Photometric interpretation (Tag 262).

samples_per_pixel: Option<u16>

Samples per pixel (Tag 277).

page_count: Option<u32>

Number of IFDs (pages/frames) in the file.

page_name: Option<String>

Page name (Tag 285). None if not present.
