Plot Image Grid — plot_image

Displays the image in the current device.

plot_image_grid(input_list, dim = c(1, 1), asp = 1, draw_grid = FALSE)

Arguments

input_list: List of array (or matrix) image inputs.
dim: Default c(1,1). Width by height of output grid.
asp: Default 1. Aspect ratio of the pixels(s). For example, an aspect ratio of 4/3 will slightly widen the image. This can also be a vector the same length of input_list to specify an aspect ratio for each image in the grid.
draw_grid: Default FALSE. If TRUE, this will draw a grid in the background to help disambiguate the actual image from the device (helpful if the image background is the same as the device's background).

Examples

if(run_documentation()){
#Plot the dragon array
plot_image_grid(list(dragon, 1-dragon), dim = c(1,2))
}

if(run_documentation()){
plot_image_grid(list(dragon, 1-dragon), dim = c(2,1))
}

if(run_documentation()){
plot_image_grid(list(dragon, NULL, 1-dragon), dim = c(2,2), asp = c(2,1,1/2))
}

if(run_documentation()){
plot_image_grid(list(dragon, NULL, NULL, dragon), dim = c(2,2), asp = c(2,1,1,1/2))
}

if(run_documentation()){
#Plot alongside the depth matrix
dragon_depth_reoriented = render_reorient(dragondepth,
                                         transpose = TRUE,
                                         flipx = TRUE)/2000
plot_image_grid(list(dragondepth/2000, dragon, dragon, dragondepth/2000),
               dim = c(2,2))
