Usage

Import the library using import trex_imager_readfile

Read a single file

>>> import trex_imager_readfile
>>> filename = "path/to/rgb_data/2020/01/01/fsmi_rgb-01/ut06/20200101_0600_fsmi_rgb-01_full.pgm.gz"
>>> img, meta, problematic_files = trex_imager_readfile.read_rgb(filename)

Read multiple files

>>> import trex_imager_readfile, glob
>>> file_list = glob.glob("path/to/files/2020/01/01/fsmi_rgb-01/ut06/*full.pgm*")
>>> img, meta, problematic_files = trex_imager_readfile.read_rgb(file_list)

Read using multiple worker processes

>>> import trex_imager_readfile, glob
>>> file_list = glob.glob("path/to/files/2020/01/01/fsmi_rgb-01/ut06/*full.pgm*")
>>> img, meta, problematic_files = trex_imager_readfile.read_rgb(file_list, workers=4)
