Detailed Description

Base class for Stroke Shaders. Any Stroke Shader must inherit from this class and overload the shade() method. A StrokeShader is designed to modify any Stroke's attribute such as Thickness, Color, Geometry, Texture, Blending mode... The basic way to achieve this operation consists in iterating over the StrokeVertices of the Stroke and to modify each one's StrokeAttribute. Here is a python code example of such an iteration:

 it = ioStroke.strokeVerticesBegin() while not it.isEnd(): att =
it.getObject().attribute()
     ## perform here any attribute modification
     it.increment()

Here is a C++ code example of such an iteration:

 for (StrokeInternal::StrokeVertexIterator v = ioStroke.strokeVerticesBegin(), vend =
ioStroke.strokeVerticesEnd(); v != vend;
     ++v)
 {
     StrokeAttribute& att = v->attribute();
     // perform any attribute modification here...
 }

shade()

int Freestyle::StrokeShader::shade ( Stroke &  ioStroke ) const

virtual

The shading method. This method must be overloaded by inherited classes.

Parameters

ioStroke

The stroke we wish to shade. this Stroke is modified by the Shader (which typically modifies the Stroke's attribute's values such as Color, Thickness, Geometry...)
