Constructor & Destructor Documentation

MonoPictureFrame() [1/2]

MonoPictureFrame::MonoPictureFrame ( boost::filesystem::path  path )

explicit

Make a picture frame from a JPEG2000 file.

Parameters

path	Path to JPEG2000 file.

Definition at line 59 of file mono_picture_frame.cc.

MonoPictureFrame() [2/2]

MonoPictureFrame::MonoPictureFrame ( ASDCP::JP2K::MXFReader *  reader, int  n, std::shared_ptr< DecryptionContext >  c, bool  check_hmac  )

private

Make a picture frame from a 2D (monoscopic) asset.

Parameters

reader	Reader for the asset's MXF file.
n	Frame within the asset, not taking EntryPoint into account.
c	Context for decryption, or 0.
check_hmac	true to check the HMAC and give an error if it is not as expected.
