virtual ASPOSE_FONT_SHARED_API void AssignDataFrom (System::SharedPtr< TtfTableBase > table)

Designed to copy data from another table with same type, for example hhea->hhea, hmtx->hmtx. This mechanism can be helpful when table of generated font needed to copy data from another existing font(not generated) to avoid problems with linking to data source(source table from existing font has link to data source(offset, length), but this link data is superfluous for destination table, so full copy (method like Copy()) is not decision for this case. Let the table takes necessary data via this assigning mechanism. More...
