Rejig linescan images.

ijtiff has the fourth dimension of an ijtiff_img as its time dimension. However, some linescan images (images where a single line of pixels is acquired over and over) have the time dimension as the y dimension, (to avoid the need for an image stack). These functions allow one to convert this type of image into a conventional ijtiff_img (with time in the fourth dimension) and to convert back.

linescan_to_stack(linescan_img)

stack_to_linescan(img)

Arguments

linescan_img	A 4-dimensional array in which the time axis is the first axis. Dimension 4 must be 1 i.e. dim(linescan_img)[4] == 1.
img	A conventional ijtiff_img, to be turned into a linescan image. Dimension 1 must be 1 i.e. dim(img)[1] == 1.

Value

The converted image, an object of class ijtiff_img.

Examples

linescan <- ijtiff_img(array(rep(1:4, each = 4), dim = c(4, 4, 1, 1)))
print(linescan)
