Export RLum.Data.Image and RLum.Data.Spectrum objects to TIFF Images

Simple wrapper around tiff::writeTIFF to export suitable RLum objects to TIFF images. Per default 16-bit TIFF files are exported.

Usage

write_R2TIFF(object, file = tempfile(), norm = 65535, ...)

Arguments

object: RLum.Data.Image or RLum.Data.Spectrum object (required): input object, can be a list of such objects.
file: character (required): name of the output file.
norm: numeric (with default): normalisation value. Usually, in imaging applications the pixel values are integer count values, but values in TIFF files must be in the 0-1 range. Normalising to the to the highest 16-bit integer values - 1 ensures that the numerical values are retained in the exported image. If 1 nothing is normalised.
...: further arguments to be passed to tiff::writeTIFF.

Value

A TIFF file

Function version
