Imread flags

Variants

IMREAD_UNCHANGED

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

IMREAD_GRAYSCALE

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

IMREAD_COLOR

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

IMREAD_ANYDEPTH

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

IMREAD_ANYCOLOR

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

IMREAD_LOAD_GDAL

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

IMREAD_REDUCED_GRAYSCALE_2

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

IMREAD_REDUCED_COLOR_2

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

IMREAD_REDUCED_GRAYSCALE_4

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

IMREAD_REDUCED_COLOR_4

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

IMREAD_REDUCED_GRAYSCALE_8

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

IMREAD_REDUCED_COLOR_8

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

IMREAD_IGNORE_ORIENTATION

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