File Structure

Hi;

I'm new with Vector Toolkit, so I don't have any idea yet what to do.  Currently I'm using LeadTools 14.5 and my problem is how can I possibly extract the data structure of the file being read by your Toolkit!  Because we I have a program that maintains a proprietary format and I wanted to use leadtools in import and export function.  But as I see it, I can not find any information how can I extract the structure of the file, like the dxf file so I can convert it to our own format.

Hope you can help me, like giving example or anything that can help me achieve y goal.

Thanks

I'm sorry but we do not give out such information.

What type of data are you going to get? LeadTools has own primitives and you can use it and convert into your data format. Describe your problem more exactly.

Hi Alexy;

Like for example I would like to open a dxf file and using leadtools I wanted to know how can I exactly get the information if the item I'm reading/opening is a polyline, a symbol or block and the likes.  Also how can I extract its features coordinates.  These are just a few information I need to know so I can easily adapt it in our data format.

Thanks in advance.

If you're just wanting to get information about each object, then do this.  Load the image, call GetLayerByIndex, EnuObjects, in the EnumObjects callback we give you an ILEADVectorObject which holds the values for each object.

It's very easy to get info...

class MyVector : public LVectorWindow     
{
public:
   MyVector( L_INT index, HWND hWnd );
   virtual MyVector

   virtual L_INT EnumObjectsCallBack( pVECTORHANDLE pVector, pVECTOROBJECT pObject );
   void GetObjects();
   ... 
}

...
void GetObjects()
{
   EnumObjects();
}
...

L_INT CLTVector::EnumObjectsCallBack(pVECTORHANDLE pVector, pVECTOROBJECT pObject)
{
 switch( pObject->nType )
 {
 case VECTOR_VERTEX:
  {
   VECTORVERTEX vertex;
   LVectorBase vectorBase( pVector );
   LVectorVertex vectorVertex( pObject, &vectorBase );
   vectorVertex.LockObject( &vertex );

   //!- Do something -!  
   // vertex.Object.nType;
   // vertex.Point.x;
   // vertex.Point.y;
   // vertex.Point.z;

   vectorVertex.UnlockObject( &vertex );
  }
  break;
        ... 
        }
}
...
