Get the image from *Image class

Source: R/image.R
imgRaster.Rd

In SFE, S4 classes inheriting from VirtualSpatialImage have been implemented to make these image classes compatible with SpatialExperiment.

Usage

# S4 method for class 'SpatRasterImage'
imgRaster(x, maxcell = 1e+07, col = terra::map.pal("viridis", 100))

# S4 method for class 'BioFormatsImage'
imgRaster(x, resolution = 4L)

# S4 method for class 'ExtImage'
imgRaster(x)

Arguments

x

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

maxcell

positive integer. Maximum number of cells to use for the plot

col

vector of colors. The default is map.pal("viridis", 100)

resolution

Resolution to read in from OME-TIFF, defaults to 4, which is a medium resolution in Xenium.

Value

Since version 1.9.8, imgRaster will return an array of hex colors, or the raster object, as required by SpatialExperiment. This will break older SFE code calling imgRaster.
