Variants

Unchanged

If set, return the loaded image as is (with alpha channel, otherwise it gets cropped

Grayscale

If set, always convert image to the single channel grayscale image.

Color

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

AnyDepth

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

AnyColor

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

LoadGdal

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

ReducedGrayscale2

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

ReducedColor2

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

ReducedGrayscale4

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

ReducedColor4

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

ReducedGrayscale8

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

ReducedColor8

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