pydicom.fileutil.length_of_undefined_length

pydicom.fileutil.length_of_undefined_length(fp, delimiter, is_little_endian, read_size=128, rewind=True)

Search through the file to find the delimiter and return the length of the data element.

Parameters

• fp (file-like) – The file-like to read.

• delimiter – See find_delimiter() for parameter info.

• is_little_endian (bool) – True if little endian, False otherwise.

• read_size (int) – See find_bytes() for parameter info.

• rewind (bool) – Flag to rewind to initial position after searching.

Returns

Byte offset to the delimiter.

Return type

int

Notes

Note the data element that the delimiter starts is not read here, the calling routine must handle that. Delimiter must be 4 bytes long.
