rotateImg: Rotate image

In pachterlab/SpatialFeatureExperiment: Integrating SpatialExperiment with Simple Features in sf

Rotate image

Description

As in SpatialExperiment, rotation here must be a multiple of 90 degrees.

Usage

## S4 method for signature 'SpatRasterImage'
rotateImg(x, degrees, maxcell = 1e+07, ...)

## S4 method for signature 'BioFormatsImage'
rotateImg(x, degrees, ...)

## S4 method for signature '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 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

SpatRasterImage will be loaded into memory and converted to ExtImage. Otherwise *Image object of the same class.
