Camera

SimpleKivy.SimpleKivy.Camera(k=None, legacy=False, **kwargs)

Creates a custom Camera widget dynamically with added functionalities.

Dynamic Creation Parameters

legacy: bool

Whether the legacy (kivy.uix.camera.Camera) or the new (SimpleKivy.kvWidgets.Camera) Camera is used as base.

• False: Uses SimpleKivy’s Camera.

• True: Uses legacy kivy’s Camera.

Defaults to False.

When legacy = False, requires the cv2 module to work. install it with pip install opencv-python.

Parameters

k: None, str, or NOTKEY

Key specification for quick acess:

• None: Automatically sets an int value.

• str: Use specific string key.

• NOTKEY: Special flag indicating no key should be used.

size: str or sequence of 2 ints

Size specification of the widget:

• str: "x{width}": Sets widget width and size_hint_x = None.

• str: "y{height}": Sets widget height and size_hint_y = None.

• str: "xchildren": Sets size_hint_x = None and binds this widget’s width to the sum of the widths of its children.

• str: "ychildren": Sets size_hint_y = None and binds this widget’s height to the sum of the heights of its children.

• str: "xchild_max": Sets size_hint_x = None and binds this widget’s width to the child with the maximum width.

• str: "ychild_max": Sets size_hint_y = None and binds this widget’s height to the child with the maximum height.

You can combine up to two of the above size string specifications.

• str: "{number}": Processed as size = (number, number) and size_hint = (None,None). Cannot be combined with other string specifications.

• sequence: (int, int): Size of the widget. Same as Kivy. Has no effect if size_hint argument is not set to None.

Example:

sk.Camera(size = "y35")
sk.Camera(size = "x120y35")
sk.Camera(size = "xchildreny40")
sk.Camera(size = "xchildrenychildren")
sk.Camera(size = "xchild_maxy40")
sk.Camera(size = "60")
sk.Camera(size = (120,35), size_hint = (None, None))

enable_events: bool

Whether the widget will send events to the event_manager set in MyApp using the widgets k/id property as event identifier.

• True: Triggers events.

• False: Doesn’t trigger events.

on_event: str, iterable (tuple or list), dict

Defines which events/property changes will trigger the event_manager. Only has effect if enable_events = True.

• str: Name of the event or property that will trigger the event_manager.

• iterable: [str, str, ...]: Will trigger events for each name in the iterable.

• dict: {"{event_name}": callback}: Calls instance.bind(**on_event) during widget creation.

Example:

sk.Camera(enable_events = True, on_event = 'width')
sk.Camera(enable_events = True, on_event = 'on_touch_down')
sk.Camera(enable_events = True, on_event = ['width','height','pos'])
sk.Camera(enable_events = True, on_event = {"size": lambda ins,v: print("size =",v)})

do_dot_subevent: bool

Adds a “.” to describe the event when triggering the event_manager.

• True: The event identifier is str(widget.id)+".{event_name}".

• False: The event identifier is the same as the widget’s k/id.

Default is False.

Returns

Camera widget created dynamically.

Kivy Bases

Image or Camera (when legacy).

This page only details the new or modified features. All other parameters inherit from the base Kivy widgets and can be found in the official Kivy documentation.
