Transpose images

Source: R/image.R
transposeImg.Rd

Swap rows and columns of images. In effect, this will flip the image around the diagonal running from top left to bottom right.

Usage

# S4 method for SpatRasterImage
transposeImg(x, filename = "", maxcell = NULL, ...)

# S4 method for BioFormatsImage
transposeImg(x, ...)

# S4 method for ExtImage
transposeImg(x, ...)

Arguments

x

An object of class *Image as implemented in this package.

filename

Output file name for transformed SpatRaster.

maxcell

Max number of pixels to load SpatRasterImage into memory. The default 1e7 is chosen because this is the approximate number of pixels in the medium resolution image at resolution = 4L in Xenium OME-TIFF to make different methods of this function consistent.

...

Ignored. It's there so different methods can all be passed to the same lapply in the method for SFE objects. Some methods have extra arguments.

Value

For SpatRasterImage and ExtImage, object of the same class. For BioFormatsImage, the image of the specified resolution is read into memory and then the ExtImage method is called, returning

ExtImage. For the extent: xmin and xmax are switched with ymin and ymax.
