ijtiff_img class.

A class for images which are read or to be written by the ijtiff package.

ijtiff_img(img, ...)

as_ijtiff_img(img, ...)

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,]    1    3
#> [2,]    2    4
#> ── TIFF tags ───────────────────────────────────────────────────────────────────
