Package libavg :: Module avg :: Class Camera

Class Camera

A node that displays the image of a camera. The properties are the same as the camera properties in .avgtrackerrc and are explained under https://www.libavg.de/wiki/index.php/Tracker_Setup.

Instance Methods

getWhitebalanceU(...)

getWhitebalanceV(...)

isAvailable(...)

play()
Starts camera playback.

setWhitebalance(...)

stop()
Stops camera playback and closes the camera object.

Inherited from RasterNode

Bitmap

getBitmap()
Returns a copy of the bitmap that the node contains.

getOrigVertexCoords()
Returns the unwarped coordinate of all vertices as a list of lists.

getWarpedVertexCoords()
Returnes the current coordinate of all vertices as a list of lists.

setWarpedVertexCoords(grid)
Changes the current coordinates of all vertices.

Inherited from AreaNode

AreaNode

getElementByPos(pos)
Returns the topmost child node that is at the position given.

mediasize

getMediaSize()
Returns the size in pixels of the media in the node.

Inherited from Node

__eq__(...)

__hash__(...)
hash(x)

__init__(...)
Raises an exception This class cannot be instantiated from Python

__ne__(...)

abspos

getAbsPos(relpos)
Transforms a position in coordinates relative to the node to a position in window coordinates.

node

getParent()
Returns the container (AVGNode or DivNode) the node is in.

relpos

getRelPos(abspos)
Transforms a position in window coordinates to a position in coordinates relative to the node.

releaseEventCapture(cursorid)
Restores normal mouse operation after a call to setEventCapture().

setEventCapture(cursorid)
Sets up event capturing so that cursor events are sent to this node regardless of the cursor position.

setEventHandler(type, source, pyfunc)
Sets a callback function that is invoked whenever an event of the specified type from the specified source occurs.

None

unlink(kill)
Removes a node from it's parent container.

Static Methods

resetFirewireBus()
Frees all allocated bandwidth and devices on the firewire bus.

	opacity A measure of the node's transparency.
	sensitive A node only reacts to events if sensitive is true.

Method Details

resetFirewireBus()
Static Method

Frees all allocated bandwidth and devices on the firewire bus. Helpful if a program using a firewire device has crashed leaving resources allocated. Note that all firewire devices (including for instance external hard drives) are affected.
