ImageMagick is installed on most Linux distros and is available for macOS and Windows: magick input.pfm output. If you cannot read your PFM files in Python, you could convert them at the command line using ImageMagick to another format, such as TIFF, that can store floating point samples. # Unpack floats with appropriate endianness Print('DEBUG: channels='.format(BigEndian)) Print('ERROR: Not a valid PFM file',file=sys.stderr) # Line 1: PF=>RGB (3 channels), Pf=>Greyscale (1 channel) It may contain inefficiencies or bad practices because I do not speak Python. I pieced together a simple reader myself below that seems to work fine on a few sample images I found around the 'net and generated with ImageMagick. The ImageIO documentation here suggests there is a FreeImage reader you can download and use. I am not at all familiar with Python, but here are a few suggestions on reading a PFM ( Portable Float Map) file.

The vast majority of the PACK files can be opened in my situation except the one which I want the most which is landunitstables, the file which has the stats of units. Best way to convert your PFM to PDF file in seconds. This program has been compiled and tested with OpenCV 2.4.11 on Windows ans Linux environments. Note that in the current version the files are loaded and saved using little endian format only. A description of the PFM file format can be found here. PFM files can be loaded to an OpenCV matrix (Mat) and saved from an OpenCV Mat to a PFM file. We dont recommend Maverick photo viewer because it doesnt seem to show depth images properly. This open source program provides functions to read and write PFM files. One of the good viewer to view this file format is PfmPad.
