@Jabiertxo : Thankyou You seem to have a good level of knowledge of working of the B-Splines and of how curves implemented in lib2geom. I don't know much of code's working. I will study the code and you can help me with the understanding.
@Pieter Barendrecht, seems to know A LOT about Beizer Implementations, I guess he seems the GOTO GUY for technical probelms . :)

Good morning.
I am very glad that people are getting involved in the project. I thank especially Arshdeep Singh for offering with such enthusiasm, I look forward to working with him and learn.
I am also happy news for the project provided by Johan Engelen lib2geom of the project, which seems key to the achievement of the B-Splines in Inkscape.
For my part I contribute my part of the way and start coding before I point out what I think we need to get.
The BSplines give the artist total control to make layouts without using handlers, giving a speed and accuracy, I think, unique in the world of drawing.
This feature is primarily patent while you draw each stroke, implement this feature at the end of the path has no make much sense.
I therefore propose branch-if so-called the project into two consecutive parts:
The first is a part facilitator also has benefits spiro tool. They are getting while drawing a spiro curve, the mark of the "road" is already the final route, without going into consideration to show both paths and / or buttons to switch.
The second would be to implement a curve BSpline like a Spiro.
In both modes "spiro" and "BSPLINE" would be important to assign a key to draw the next point is a corner point.
Do you think well this way?
Buenos días.
Estoy muy contento de la gente que se está involucrando en el proyecto. Le doy gracias especialmente a Arshdeep Singh por ofrecerse con ese entusiasmo, estoy deseoso de poder trabajar junto a el y aprender.
Me alegra también la noticia a favor del proyecto facilitada por Johan Engelen de el proyecto lib2geom, que parece clave para la consecución de las B-Splines en Inkscape.
Yo por mi parte aporto mi parte del camino y antes de empezar a codificar quiero puntualizar lo que pienso que tenemos que conseguir.
Las BSplines dan al dibujante total control al realizar trazados sin necesidad de usar manejadores, dando una velocidad y precisión únicas -creo- en el mundo del dibujo.
Esta característica es patente principalmente mientras se va dibujando cada trazo, implementar dicha característica al final de realizar el trazado no tiene mucho sentido.
Por ello propongo bifurcar -si se llama así- el proyecto en dos partes consecutivas:
La primera es una parte facilitadora que además tiene beneficios para la herramienta spiro. Se trata de conseguir mientras se dibuja una curva spiro, que la marca del "camino" sea ya el trazado final, sin entrar en consideración de mostrar ambos trayectos y / o botones para alternar.
La segunda seria implementar la curva BSpline como una Spiro.
En ambos modos "spiro" y "bspline" seria importante asignar una tecla para que el siguiente punto a dibujar sea un punto de esquina.
¿Os parece bien este camino?
