diplomat.utils.frame_store_api.DLFSHeader

class diplomat.utils.frame_store_api.DLFSHeader(*args, **kwargs)

Bases: MutableMapping

Stores some basic info about a frame store…

Below are the fields in order, their names, types and default values:

(“number_of_frames”, int, 0), (“frame_height”, int, 0), (“frame_width”, int, 0), (“frame_rate”, float, 0), (“stride”, float, 0), (“orig_video_height”, int, 0), (“orig_video_width”, int, 0), (“crop_offset_y”, int or None if no cropping, None), (“crop_offset_x”, int or None if no cropping, None), (“bodypart_names”, list of strings, []),

__init__(*args, **kwargs)

Make a new DLFSHeader. Supports tuple style construction and also supports setting the fields using keyword arguments. Look at the class documentation for all the fields.

Methods

__init__(*args, **kwargs)	Make a new DLFSHeader.
clear()
get(k[,d])
items()
keys()
pop(k[,d])	If key is not found, d is returned if given, otherwise KeyError is raised.
popitem()	as a 2-tuple; but raise KeyError if D is empty.
setdefault(k[,d])
to_list()
update([E, ]**F)	If E present and has a .keys() method, does: for k in E.keys(): D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v
values()

Attributes

GET_IDX
GET_VAR_CAST
SUPPORTED_FIELDS

__delitem__(key) → Any

Clear the specified header property to its default value.

__getitem__(key) → Any

Get the specified header property, returning its current value.

__iter__() → Iterator

Iterate the keys of the header in order.

__len__() → int

Get the length of this header (Should always be 10).

__setitem__(key, value)

Set the value of the specified header property.

clear() → None.  Remove all items from D.

get(k[, d]) → D[k] if k in D, else d.  d defaults to None.

items() → a set-like object providing a view on D's items

keys() → a set-like object providing a view on D's keys

pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised.

popitem() → (k, v), remove and return some (key, value) pair

as a 2-tuple; but raise KeyError if D is empty.

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D

update([E, ]**F) → None.  Update D from mapping/iterable E and F.

If E present and has a .keys() method, does: for k in E.keys(): D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

values() → an object providing a view on D's values
