createGiottoLargeImage

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,
  flip_vertical = FALSE,
  flip_horizontal = FALSE,
  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

flip_vertical

flip raster in a vertical manner

flip_horizontal

flip raster in a horizontal manner

xmax_bound, xmin_bound, ymax_bound, 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
