As in SpatialExperiment
, rotation here must be a multiple of 90
degrees.
Usage
# S4 method for class 'SpatRasterImage'
rotateImg(x, degrees, maxcell = 1e+07, ...)
# S4 method for class 'BioFormatsImage'
rotateImg(x, degrees, ...)
# S4 method for class 'ExtImage'
rotateImg(x, degrees, ...)
Arguments
- x
An object of class
*Image
as implemented in this package.- degrees
How many degrees to rotate. Positive number means clockwise and negative number means counterclockwise.
- 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 atresolution = 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
SpatRasterImage
will be loaded into memory and converted to
ExtImage
. Otherwise *Image
object of the same class.
