Creates a list of large giotto images that can be added to a Giotto object. Generates deep copy of SpatRaster
Usage
createGiottoLargeImageList(
raster_objects,
names = "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_objects
vector of image paths or terra SpatRaster image objects
- names
vector of names for the images
- 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
Examples
image_test <- system.file("extdata/toy_intensity.tif",
package = "GiottoClass"
)
createGiottoLargeImageList(raster_objects = image_test)
