Halftone3::Halftone3 ( )

Member Function Documentation

bool Halftone3::set_param ( const String param,
const ValueBase value 
)
virtual

Sets the value for the given parameter.

Reimplemented from synfig::Layer_Composite.

References synfig::ValueBase::get_type(), IMPORT_VALUE_PLUS, Halftone::param_angle, and Halftone::param_origin.

ValueBase Halftone3::get_param ( const String param) const
virtual

Gets the value of the given parameter.

If it is unknown then call the ancestor's get param member to see if it can handle that parameter's string.

Reimplemented from synfig::Layer_Composite.

References EXPORT_NAME, EXPORT_VALUE, EXPORT_VERSION, Halftone::param_angle, and Halftone::param_origin.

Color Halftone3::get_color ( Context  context,
const Point pos 
) const
virtual

Gets the blend color of the Layer in the context at pos.

Parameters
contextContext iterator referring to next Layer.
posPoint which indicates where the Color should come from
See Also
Context::get_color()

Reimplemented from synfig::Layer.

References synfig::Layer_Composite::get_amount(), synfig::Layer_Composite::get_blend_method(), and synfig::Context::get_color().

bool Halftone3::accelerated_render ( Context  context,
Surface surface,
int  quality,
const RendDesc renddesc,
ProgressCallback cb 
) const
virtual
bool Halftone3::accelerated_cairorender ( Context  context,
cairo_t *  cr,
int  quality,
const RendDesc renddesc,
ProgressCallback cb 
) const
virtual
synfig::Layer::Handle Halftone3::hit_check ( synfig::Context  context,
const Point point 
) const
virtual

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

Parameters
contextContext iterator referring to next Layer.
pointThe point to check
Returns
The handle of the layer under point. If there is not a layer under point, then returns an empty handle.
See Also
Context::hit_check

Reimplemented from synfig::Layer.

Layer::Vocab Halftone3::get_param_vocab ( void  ) const
virtual

Gets the parameter vocabulary. To be overrided by the derived.

First fills the returning vocabulary with the ancestor class

Now inserts the two parameters that this layer knows.

Reimplemented from synfig::Layer_Composite.

References _, TYPE_DIAMOND, TYPE_LIGHTONDARK, TYPE_STRIPE, and TYPE_SYMMETRIC.

virtual bool Halftone3::reads_context ( ) const
inlinevirtual

Returns true if the layer needs to be able to examine its context.

context to render itself, other than for simple blending. For example, the blur layer will return true - it can't do its job if it can't see its context, and the circle layer will return false - rendering a circle doesn't depend on the underlying context until the final blend operation.
