This function aligns and crops the image using either base or mapview visualization. This is useful to prepare the images to be analyzed with analyze_objects_shp()

Usage

Arguments

img

An optional Image object

viewer

The viewer option. If not provided, the value is retrieved using get_pliman_viewer(). This option controls the type of viewer to use for interactive plotting.

To set this argument globally for all functions in the package, you can use the set_pliman_viewer() function. For example, you can run set_pliman_viewer("mapview") to set the viewer option to "mapview" for all functions.
