Introducere

Exportul si conversia valorii unui nod - ValueNode/ro sunt printre cele mai interesante caracteristici ale aplicatiei synfig. O combinatie a acestora permite utilizatorului sa organizeze animatii complexe prin modificarea catorva parametri. Vedeti lectia de urmarire a unui element Doc:Following_a_BLine.

Uneori e posibil sa doriti ca sa faceti aceeasi combinatie a valorilor exportate si a tipurilor convertite. Si este obositor sa repetati acelasi lucru de mai multe ori.

Exista o metoda de evitare a repetarii operatiei si de refolosire a valorilor exportate si convertite.

Inchipuiti-va ca aveti o situatie in care ..... you have a cool conversion combination and want to use it into another already done animation. You can do the following:

1. In the animation file that has the cool conversion do:
   1. Export all the values that you want to control. For example if parameter 'a' is a=b+c then you should export three parameters: 'a', 'b' and 'c'. The exported parameter 'a' will be an Add parameter and will be calculated based on the 'b' and 'c' exported parameters.
   2. Delete all the layers (you don't need them at all, because you only need the cool conversion combination). Save the file with other name ("master.sifz"). This will be the main file.
2. Go to File->Import and select the file that have the current done animation where on you want to use the cool exported valuenodes combination.
3. Then select the imported paste canvas layer and go to its canvas parameter and export it. Set a meaningful name. Save the "master" file and close it.
4. Open the "master" file again and you'll see that the imported animation file (already an exported canvas) has an expand triangle that allows to select the layers that are inside of it.
5. Select the parameter of the layer of the imported canvas that you want and link the parameter to any of the "master" canvas exported values that are accessible to the children layers parameters, using the right click mouse button.

That's all folks! ;-)
