Package libavg :: Module avg :: Class RasterNode

Class RasterNode

Base class for all nodes that have a direct 2d raster representation. This includes Image, Word, Camera, and Video nodes. RasterNodes can be rotated. Warping of RasterNodes is implemented using a grid of reference points. The position of each of these points can be changed.

Instance Methods

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 Node: __init__, getParent, getRelPos, releaseEventCapture, setEventCapture, setEventHandler

Inherited from unreachable.instance: __new__

Inherited from object: __delattr__, __getattribute__, __hash__, __reduce__, __reduce_ex__, __repr__, __setattr__, __str__

Properties
	angle The angle that the node is rotated to in radians.
	blendmode The method of compositing the node with the nodes under it.
	maxtileheight The maximum width and height of the tiles used for warping.
	maxtilewidth The maximum width and height of the tiles used for warping.
	pivotx x coordinate of the point that the node is rotated around.
	pivoty y coordinate of the point that the node is rotated around.

Method Details

getBitmap()

Returns a copy of the bitmap that the node contains.

Returns:

Bitmap

setWarpedVertexCoords(grid)

Changes the current coordinates of all vertices.

Parameters:

grid - list of lists of coordinate tuples.

Property Details

angle

The angle that the node is rotated to in radians. 0 is unchanged, 3.14 is upside-down.

Get Method:: unreachable(...)
Set Method:: unreachable(...)

blendmode

The method of compositing the node with the nodes under it. Valid values are 'blend', 'add', 'min' and 'max'.

Get Method:: unreachable(...)
Set Method:: unreachable(...)

maxtileheight

The maximum width and height of the tiles used for warping. The effective tile size is also dependent on hardware and driver limits. (ro)

pivotx

x coordinate of the point that the node is rotated around. Default is the center of the node.
