pydicom.filebase.DicomIO

class pydicom.filebase.DicomIO(*args: Any, **kwargs: Any)

File object which holds transfer syntax info and anything else we need.

__init__(*args: Any, **kwargs: Any) → None

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(*args, **kwargs)	Initialize self.
read([length, need_exact_length])	Reads the required length, returns EOFError if gets less
read_beUL()	Return an unsigned long read with big endian byte order
read_beUS()	Return an unsigned short from the file with big endian byte order
read_be_tag()	Read and return two unsigned shorts (big endian) from the file.
read_leUL()	Return an unsigned long read with little endian byte order
read_leUS()	Return an unsigned short from the file with little endian byte order
read_le_tag()	Read and return two unsigned shorts (little endian) from the file.
write_UL(val)	Write an unsigned long with little endian byte order
write_US(val)	Write an unsigned short with little endian byte order
write_beUL(val)	Write an unsigned long with big endian byte order
write_beUS(val)	Write an unsigned short with big endian byte order
write_leUL(val)	Write an unsigned long with little endian byte order
write_leUS(val)	Write an unsigned short with little endian byte order
write_tag(tag)	Write a dicom tag (two unsigned shorts) to the file.

read(length: Optional[int] = None, need_exact_length: bool = False) → bytes

Reads the required length, returns EOFError if gets less

If length is None, then read all bytes

read_beUL() → int

Return an unsigned long read with big endian byte order

read_beUS() → int

Return an unsigned short from the file with big endian byte order

read_be_tag() → Tuple[int, int]

Read and return two unsigned shorts (big endian) from the file.

read_leUL() → int

Return an unsigned long read with little endian byte order

read_leUS() → int

Return an unsigned short from the file with little endian byte order

read_le_tag() → Tuple[int, int]

Read and return two unsigned shorts (little endian) from the file.

write_UL(val: int) → None

Write an unsigned long with little endian byte order

write_US(val: int) → None

Write an unsigned short with little endian byte order

write_beUL(val: int) → None

Write an unsigned long with big endian byte order

write_beUS(val: int) → None

Write an unsigned short with big endian byte order

write_leUL(val: int) → None

Write an unsigned long with little endian byte order

write_leUS(val: int) → None

Write an unsigned short with little endian byte order

write_tag(tag: Union[int, str, Tuple[int, int], BaseTag]) → None

Write a dicom tag (two unsigned shorts) to the file.
