The image hue is adjusted by converting the image to HSV and cyclically shifting the intensities in the hue channel (H). The image is then converted back to original image mode.
transform_adjust_hue(img, hue_factor)A magick-image, array or torch_tensor.
(numeric): How much to shift the hue channel. Should be
in [-0.5, 0.5]. 0.5 and -0.5 give complete reversal of hue channel
in HSV space in positive and negative direction respectively. 0 means
no shift. Therefore, both -0.5 and 0.5 will give an image with
complementary colors while 0 gives the original image.
hue_factor is the amount of shift in H channel and must be in the
interval [-0.5, 0.5].
