2.0 Enhancements

Service Pack Release 19.30

The HInputHandlerOptions::m_bPRCImportHiddenObjects option has been added. If set to true, representation items marked as 'hidden' will be imported but have their visibility turned off. If set to false, representation items marked as hidden will be skipped and not imported. Setting this value to false gives the pre-option behavior and is the default. See the HIO_Exchange programming guide for more info.

Service Pack Release 19.25

Printing-to-scale is now supported. This is activated by setting a 'scaling factor' for the model. Using the scaling factor, HOOPS can determine that '1 unit in world space equals 1 cm', and the hardcopy result will physically match the specified scale. Refer to Section 4.3.2 of the HOOPS/MVO Programming Guide for more information.

The HOutputHandlerOptions::m_bPrcCompressTessellation option has been added, which sets whether to compress tessellation data when exporting to PRC format. See the HIO_Publish programming guide for more info.

The HOutputHandlerOptions::m_ePrcBrepCompression option has been added, which sets the compression level for any BRep data when exporting to the PRC format. See the HIO_Publish programming guide for more info.

Minor Release 19.1

HBaseOperator and HEventInfo now support multi-touch events. Refer to Section 12.7 of the HOOPS/MVO Programming Guide for more information.

Major Release 19.0

HUtility::TwoPassPrint can handle printing arbitrarily large documents and adds margin support.
