The class GraphicsObject
Base Classes: devguide-12.html#N2Bounded , devguide-13.html#N2HierarchyNode , devguide-15.html#N2Selectable  and devguide-14.html#N2Protocols .
The class GraphicsObject defines the interface common to all
graphics objects.
For convenience of implementation, and because their interfaces are
needed elsewhere in the class hierarchy as well, some parts of this
interface are defined by the base classes:
devguide-12.html#N2Bounded provides instance variables for
the vertical and horizontal dimensions of a graphics object and
some related methods.
devguide-13.html#N2HierarchyNode provides the default
behavior for all methods related to the management of the
object hierarchy in the document.
devguide-15.html#N2Selectable defines the generic interface
and default behavior for selection.
devguide-14.html#N2Protocols has some variables that
describe the object's capabilities.
Instance Variables
GraphicsObject maintains no instance variables of its own, but uses
those managed by its base classes.
Methods
Methods defined in GraphicsObject:
Blend(other, frac1, frac2)Return the weighted average of self and other.
frac1 and frac2 are the weights (if self and
other were numbers this should be frac1 * self+ 
frac2 * other).
This method is used by the function Blend in
blend.py. If self and other can't be blended,
raise the 
blend.Mismatch exception. This is the default
behavior.
AsBezier()Return self as a PolyBezier object if possible.
If this is not possible, return 
None.
The following methods are not implemented in GraphicsObjectdirectly, but must be defined for every graphics object. The derived
classes 
devguide-16.html#N2Primitive  and devguide-17.html#N2Compound provide a default implementation for most objects.
Transform(trafo)Apply the devguide-7.htmltransformation object trafo to self. Return undo info.
Translate(offset)Translate (move) self by offset. offset is a devguide-5.htmlpoint object . Return undo info.
DrawShape(device [, clip])Draw self on device. device is a graphics device
.
The optional parameter clip is only provided if the object
is used as a clip mask. If it is provided its value is 1.
Objects that can be used as clip masks (their 
is_clip flag
is true) request appropriate clipping from the graphics device.
Objects that cannot be used as clip masks don't need to accept
it.
(Note: The clipping interface for the high level drawing
operations of the graphics devices is somewhat experimental)
SaveToFile(file)Save self to file. The argument file is currently an
instance of the class 
SKSaver which provides
special methods for the object types currently implemented in
Skencil.
