RawSubFile

class RawSubFile

Class to read a singe subfile written in .raw format. Used from RawFile to read the entire detector. Can be used directly to read part of the image.

Public Functions

RawSubFile(const std::filesystem::path &fname, DetectorType detector, size_t rows, size_t cols, size_t bitdepth, uint32_t pos_row = 0, uint32_t pos_col = 0)

SubFile constructor.

Parameters:

• fname – path to the subfile

• detector – detector type

• rows – number of rows in the subfile

• cols – number of columns in the subfile

• bitdepth – bitdepth of the subfile

Throws:

std::invalid_argument – if the detector,type pair is not supported

~RawSubFile() = default

void seek(size_t frame_index)

Seek to the given frame number.

Note

Puts the file pointer at the start of the header, not the start of the data

Parameters:

frame_index – frame position in file to seek to

Throws:

std::runtime_error – if the frame number is out of range
