Channel Manipulation

Channel Manipulation

ice.Image Shuffle(channels)

channels: List of integers specifying channel order in output (list).

Returns an image containing some or all of the channels in the original image, in a specified order.  Channel indices may be duplicated. Assumes rgbImage is of type ice.Image.

channels = [3,2,1]
bgrImage = rgbImage.Shuffle(channels)
		

ice.Image Interleave(b, channels)

b: Second image (ice.Image)
channels: List of integers representing channels in each operand image (list).

Returns an image combining channels of two images in a specified order.  The List contains both negative and positive integers: negative numbers refer to channels in the first image, and positive ones to channels in the second image. For example:

channels = [-1,-2, -3, 4]
result = a.Interleave(b, channels)
		

takes the red, green and blue channels from a and the alpha channel from b and puts them together to form the result image.

A channel index of zero is not defined.
