write_R2TIFF function

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

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

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 ): the file name and path
• norm: numeric (with default): normalisation values. Values in TIFF files must range between 0-1, however, usually in imaging applications the pixel values are real integer count values. The normalisation 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 .

Returns

A TIFF file

Function version
