Image Transposition
Transposes an image by swapping its spatial dimensions.
transpose(x)
x |
an |
The transposition of an image is performed by swapping the X and Y indices of its array representation.
A transformed version of x with its first two dimensions transposed.
The function is implemented using an efficient cash-oblivious algorithm which is typically faster than R's aperm and t functions.

x = readImage(system.file("images", "sample-color.png", package="EBImage"))
y = transpose(x)
display(x, title='Original')
display(y, title='Transposed')
## performing the transposition of an image twice should result in the original image
z = transpose(y)
