◆ close()

bool PtexWriterBase::close ( Ptex::String & error )

virtual

Close the file.

This operation can take some time if mipmaps are being generated or if there are many edit blocks. If an error occurs while writing, false is returned and an error string is written into the error parameter.

Implements PtexWriter.

Reimplemented in PtexMainWriter, and PtexIncrWriter.
