Detailed Description

Sub-class of DD::Image::Read used by NukeStudio/Hiero for timeline reads.

NukeStudio and Hiero code that uses DDImage plugins for reading source footage will create TimelineRead rather than just Read instances. This is for internal use, though if readers want to behave in some different when being used for the timeline they can test a dynamic_cast of their owning Read op to see if it's actually a TimelineRead.

Constructor & Destructor Documentation

◆ TimelineRead()

DD::Image::TimelineRead::TimelineRead ( )

We only need a default constructor, as by definition there's no node to pass through to the Read constructor.

Member Function Documentation

◆ filename()

void DD::Image::TimelineRead::filename ( const char * f )

These intentionally shadow the non-virtual base class methods. Setting the file name will also create the reader format, which is needed for timeline reads
