bool Layer_Shape::set_param ( const String param,
const synfig::ValueBase value 
) [virtual]

Sets the parameter described by param to value.

Parameters:
param The name of the parameter to set
value What the parameter is to be set to.
Returns:
true on success, false upon rejection or failure. If it returns false, then the Layer is assumed to remain unchanged.
See also:
get_param()
Todo:
param should be of the type const String &param

Reimplemented from synfig::Layer_Composite.

Reimplemented in synfig::Layer_Polygon.

ValueBase Layer_Shape::get_param ( const String param  )  const [virtual]

Get the value of the specified parameter.

Returns:
The requested parameter value, or (upon failure) a NIL ValueBase.
See also:
set_param()
Todo:
param should be of the type const String &

Reimplemented from synfig::Layer_Composite.

Reimplemented in synfig::Layer_Polygon.

Layer::Vocab Layer_Shape::get_param_vocab (  )  const [virtual]

Gets the paramater vocabulary.

Reimplemented from synfig::Layer_Composite.

Reimplemented in synfig::Layer_Polygon.

Color Layer_Shape::get_color ( Context  context,
const Point pos 
) const [virtual]

Gets the color of the Canvas at pos.

Parameters:
context Context iterator refering to next Layer.
pos Point which indicates where the Color should come from
See also:
Handle::get_color()

Reimplemented from synfig::Layer.

bool Layer_Shape::accelerated_render ( Context  context,
Surface surface,
int  quality,
const RendDesc renddesc,
ProgressCallback cb 
) const [virtual]

Renders the Canvas to the given Surface in an accelerated manner.

Parameters:
context Context iterator refering to next Layer.
surface Pointer to Surface to render to.
quality The requested quality-level to render at.
renddesc The associated RendDesc.
cb Pointer to callback object. May be NULL if there is no callback.
Returns:
true on success, false on failure
See also:
Handle::accelerated_render()

Reimplemented from synfig::Layer_Composite.

synfig::Layer::Handle Layer_Shape::hit_check ( synfig::Context  context,
const synfig::Point point 
) const [virtual]

Checks to see if a part of the layer is directly under point.

Parameters:
context Context iterator refering to next Layer.
point The point to check
Returns:
The handle of the layer under point. If there is not a layer under point, then returns an empty handle.

Reimplemented from synfig::Layer.

Rect Layer_Shape::get_bounding_rect (  )  const [virtual]

Reimplemented from synfig::Layer.
