## Detailed Description

class HIOUtilityDwfImport : public HInputHandler

  The HIOUtilityDwfImport is the integration class for the DWF toolkit. Using this integration class allows you to import Autodesk’s DWF (Design Web Format). This integration is based on DWF Toolkit version 7+. To use this integration class you will need to obtain a license of DWF Toolkit.

  Public Functions

  inline HIOUtilityDwfImport()
  inline ~HIOUtilityDwfImport()
  inline virtual void RegisterInputHandlerTypes()

    This abstract function must register extension types to be handled by subclassed HInputHandler instance.

    For example, the following line of code can be used to specify a class that will handle files with “stl” extensions:

  inline const char *GetOutputName()
    Returns

      A character pointer denoting the name of the handler.

  inline virtual const char *GetInputName()
    Returns

      A character pointer denoting the name of the input handler.

  inline virtual HInputHandlerStyle GetInputStyle()

    This abstract method returns the HInputHandlerStyle the HInputHandler.

    For example, the following line of code can be used for an HInputHandler that handles models:

  inline virtual const char *GetInputTypesString()

    This method must be implemented in a subclassed HInputHandler

    .

    Examples:

    The following line of code can be used to specify the stl extension:

    The following line of code can be used to specify that the jpg, bmp and gif extension are handled:

    Returns

      The extension type or types that are handled by this HInputHandler.

  HFileInputResult FileInputByKey(const wchar_t *FileName, HC_KEY key, HInputHandlerOptions *options)

    This method reads the DWF file into the segment tree underneath given key

    Parameters

      - FileName – A character pointer denoting the name of the file to be read in

      - key – HOOPS key to segment for data to load in

      - Import – options

    Returns

      InputOK if the import succeeds

  inline virtual HFileInputResult FileInputByKey(const char *FileName, HC_KEY key, HInputHandlerOptions *options)

    This method loads model data from a given file to a given HOOPS segment key. Note that this must be implemented in a subclassed HInputHandler instance handling models.

    Parameters

      - filename – The name of the file to load.

      - key – The HOOPS segment key to load model data into.

      - options – An options class containing any needed extra information for the operation.

    Returns

      The #HFileInputResult result of the input operation.
