ImreadModes
Enumerator
IMREAD_UNCHANGED Python: cv.IMREAD_UNCHANGED
If set, return the loaded image as is (with alpha channel, otherwise it gets cropped). Ignore EXIF orientation.
IMREAD_GRAYSCALE Python: cv.IMREAD_GRAYSCALE
If set, always convert image to the single channel grayscale image (codec internal conversion).
IMREAD_COLOR Python: cv.IMREAD_COLOR
If set, always convert image to the 3 channel BGR color image.
IMREAD_ANYDEPTH Python: cv.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 Python: cv.IMREAD_ANYCOLOR
If set, the image is read in any possible color format.
IMREAD_LOAD_GDAL Python: cv.IMREAD_LOAD_GDAL
If set, use the gdal driver for loading the image.
IMREAD_REDUCED_GRAYSCALE_2 Python: cv.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 Python: cv.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 Python: cv.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 Python: cv.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 Python: cv.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 Python: cv.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 Python: cv.IMREAD_IGNORE_ORIENTATION
If set, do not rotate the image according to EXIF's orientation flag.
