A class for images which are read or to be written by the ijtiff package.
Arguments
- img
An array representing the image.
For a multi-plane, grayscale image, use a 3-dimensional array
img[y, x, plane].For a multi-channel, single-plane image, use a 4-dimensional array with a redundant 4th slot
img[y, x, channel, ](see ijtiff_img 'Examples' for an example).For a multi-channel, multi-plane image, use a 4-dimensional array
img[y, x, channel, plane].
- ...
Named arguments which are set as attributes.
Value
A 4 dimensional array representing an image, indexed by img[y, x, channel, frame], with selected attributes.
Examples
img <- matrix(1:4, nrow = 2) # to be a single-channel, grayscale image
ijtiff_img(img, description = "single-channel, grayscale")
#> 2x2 pixel ijtiff_img with 1 channel and 1 frame.
#> Preview (top left of first channel of first frame):
#> [,1] [,2]
#> [1,] 1 3
#> [2,] 2 4
#> ── TIFF tags ───────────────────────────────────────────────────────────────────
#> • description: single-channel, grayscale
img <- array(seq_len(2^3), dim = rep(2, 3)) # 1 channel, 2 frame
ijtiff_img(img, description = "blah blah blah")
#> 2x2 pixel ijtiff_img with 1 channel and 2 frames.
#> Preview (top left of first channel of first frame):
