说明：  Class for processing 2D Infrared Imaging, for both reflectance IR as well as absorbance IR. Currently, the datatypes are limited to text-based files, namely: (1) OMNIC exported spectra (*.csv file) format: 4000,0 0,016 Additional step was necessary to overcome the use of commas as decimal point. (2) OPUS exported spectra (*.0000 files) format: 4000.0,0.016 (3) OMNIC Map (*.map) The class in invoked as:
