Description:
pyMRAW 0.32
pyMRAW is an open-source package, enabling the efficient use of the Photron MRAW video files in Python workflows.
It’s main feature is the use of memory-mapped (np.memmap) arrays to create memory maps to locally stored raw video files and avoid loading large amounts of data into RAM.
Warning
To take advantage of pyMRAW’s memory-mapping functionality, make sure to save MRAW files either in 8-bit or 16-bit formats, corresponding to standard data types uint8 and uint16! Using pyMRAW to read 12-bit MRAW files is possible, but requires loading the complete image data into RAM to produce standard Numpy arrays.
To load .mraw - .cihx files, simply use the pymraw.load_video function:
import pyMRAW
images, info = pyMRAW.load_video('data/beam.cihx')
