createGiottoLargeImage#

Last Updated: Mar 11, 2023

Description#

Creates a large giotto image that can be added to a Giotto subcellular object. Generates deep copy of SpatRaster

Usage#

createGiottoLargeImage(
  raster_object,
  name = "image",
  negative_y = TRUE,
  extent = NULL,
  use_rast_ext = FALSE,
  image_transformations = NULL,
  xmax_bound = NULL,
  xmin_bound = NULL,
  ymax_bound = NULL,
  ymin_bound = NULL,
  scale_factor = 1,
  verbose = TRUE
)

Arguments#

`raster_object`	terra SpatRaster image object
`name`	name for the image
`negative_y`	Map image to negative y spatial values if TRUE. Meaning that origin is in upper left instead of lower left.
`extent`	SpatExtent object to assign spatial extent. Takes priority unless use_rast_ext is TRUE.
`use_rast_ext`	Use extent from input raster object
`image_transformations`	vector of sequential image transformations - under construction
`xmax_bound, xmin_bound, ymax_bo u nd, ymin_bound`	assign min and max x and y values for image spatial placement
`scale_factor`	scaling of image dimensions relative to spatial coordinates
`verbose`	be verbose

Value#

a giottoLargeImage object
