Imread flags

Variants

IMREAD_UNCHANGED = -1

If set, return the loaded image as is (with alpha channel, otherwise it gets cropped). Ignore EXIF orientation.

IMREAD_GRAYSCALE = 0

If set, always convert image to the single channel grayscale image (codec internal conversion).

IMREAD_COLOR = 1

If set, always convert image to the 3 channel BGR color image.

IMREAD_ANYDEPTH = 2

If set, return 16-bit/32-bit image when the input has the corresponding depth, otherwise convert it to 8-bit.

IMREAD_ANYCOLOR = 4

If set, the image is read in any possible color format.

IMREAD_LOAD_GDAL = 8

If set, use the gdal driver for loading the image.

IMREAD_REDUCED_GRAYSCALE_2 = 16

If set, always convert image to the single channel grayscale image and the image size reduced 1/2.

IMREAD_REDUCED_COLOR_2 = 17

If set, always convert image to the 3 channel BGR color image and the image size reduced 1/2.

IMREAD_REDUCED_GRAYSCALE_4 = 32

If set, always convert image to the single channel grayscale image and the image size reduced 1/4.

IMREAD_REDUCED_COLOR_4 = 33

If set, always convert image to the 3 channel BGR color image and the image size reduced 1/4.

IMREAD_REDUCED_GRAYSCALE_8 = 64

If set, always convert image to the single channel grayscale image and the image size reduced 1/8.

IMREAD_REDUCED_COLOR_8 = 65

If set, always convert image to the 3 channel BGR color image and the image size reduced 1/8.

IMREAD_IGNORE_ORIENTATION = 128

If set, do not rotate the image according to EXIF’s orientation flag.

Trait Implementations

impl Clone for ImreadModes

fn clone(&self) -> ImreadModes

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImreadModes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ImreadModes> for i32

fn from(v: ImreadModes) -> Self

Converts to this type from the input type.

impl PartialEq for ImreadModes

fn eq(&self, other: &ImreadModes) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<i32> for ImreadModes

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
