raster2rgb

Path of the input multiband raster.

in_rast

(optional) Path of the output RGB JPEG image; if NULL
(default), a RasterLayer will be returned.

out_file

Path of the palette file to be used (cpt or txt),
or character value of a builtin palette ("SCL", "NDVI", the default
"generic_ndsi" or "generic_ndsi_2").

palette

(to be implemented) the value corresponding to the minimum
value of the palette (for now, only -1 is used). A quantile will be also
accepted.

minval

(to be implemented) the value corresponding to the maximum
value of the palette (for now, only 1 is used). A quantile will be also
accepted.

maxval

(optional) Path where intermediate files (VRT) will be created.
Default is a temporary directory.
If <code>tmpdir</code> is a non-empty folder, a random subdirectory will be used.

tmpdir

Internal function to create JPEG or PNG images from a
singleband raster file. This function is used by <a rd-options="" href="/link/s2_thumbnails?package=sen2r&version=1.2.1" data-mini-rdoc="sen2r::s2_thumbnails">s2_thumbnails</a>,
and it will be exported when it would be more generalised.

Functions to download Sentinel-2 optical images
and perform preliminary processing operations.
'sen2r' provides the instruments required to easily perform
(and eventually automate) the steps necessary to build a complete
Sentinel-2 processing chain.
A Graphical User Interface to facilitate data processing is also provided.
