Image data and file formats
_frame_to_dict() copies PIXet data() into a NumPy array and reshapes it to (height, width). Each frame dictionary includes name, width, height, data, minimum, maximum, nonzero, and subframes. Available subframes are read separately into subframes.
Supported save formats are None, TIFF, HDF5, and PIXET_NATIVE. TIFF writes one file per frame without conversion to display-oriented 8-bit values. HDF5 appends and flushes each completed frame in Frames mode, while Integral mode saves only the final integrated frame. PIXET_NATIVE delegates file writing to PIXet.
Interpreting values: Counting pixels represent threshold-crossing events; ToT/Energy values relate to time over threshold; Time/ToA values relate to arrival time. Do not interpret raw ToT pixel values as keV without the relevant per-device calibration. Integral frames must also be interpreted in the context of the configured mode and calibration.
