DWFObject and DWFInstance

Newbie question on DWFToolKit.  Given an instance of DWFInstance, how do I get the corresponding DWFObject?

And given a DWFObject, how do I get the associated DWFInstance?


Thank you in advance.

Thank you for your questions.

The DWF Instance is recorded in the DWF Object Definition resource and DWF Content Definition resource. Please refer to the DWF Toolkit samples “ObjectDefinitionReader” and “ReadContentDefinition” to get the DWF Instance.


The 3D DWF Object is recorded in the 3D Graphic Resource. Please refer to the toolkit sample “SimpleW3DStreamProcessor” to parse the 3D Graphic Resource; you can get each DWF Object by TK_Tag. Please refer to the DWF Toolkit help doc for more detail information about the TK_Tag.


After getting the DWF Instance and DWF Object, you can match them: the DWF Instance node Id is equal to the Tag id (which is the DWF Object node Id).


Please let us know if you have any further questions.

This is how you match DWFObject and DWFInstance:


DWFObject *obj;


DWFInstance* pInstance = piInstance->value();

DWFRenderable* pRendered = pInstance->getRenderedElement();


obj->id() == pRendered->id();
