Plot a STAC asset

Plot visual assets such as thumbnails, quicklooks, or raster previews. Supported file formats are png, jpeg, and tiff/tif. The file is resolved from the asset's local_path attribute when present, otherwise from its href. Set local_path to point the plot method at a rendered file when the asset's href is relative (for example a thumbnail written under an item directory by stac_save()).

Usage

# S3 method for class 'doc_asset'
plot(x, ...)

Arguments

x

A doc_asset object.

...

Additional arguments passed to the underlying plotting engine (currently ignored for image formats, passed to terra::plot() for GeoTIFFs).

Value

Invisibly, x.

Examples

thumb <- new_asset("thumbnail.png", title = "Thumbnail",
  roles = list("thumbnail"))
attr(thumb, "local_path") <- system.file("extdata/img/logo.png",
  package = "rstatic")
if (nzchar(attr(thumb, "local_path"))) plot(thumb)
