  • DPXimage.h File needed by dpxReader/Writer
  • dpxReader.cpp The DPX spec supports a wide variety of header fields, not all of which have been implemented in Nuke. Our reader source is provided here for those users who encounter a flavor that we do not yet support and need to implement a custom reader to handle it before a Nuke release with built-in support can be made available.
  • dpxWriter.cpp The DPX spec supports a wide variety of header fields, not all of which have been implemented in Nuke. Our reader source is provided here for those users who encounter a flavor that we do not yet support and need to implement a custom reader to handle it before a Nuke release with built-in support can be made available.
  • exrGeneral.h Nuke's EXR i/o which accomodates files with large numbers of channels.
  • ExrChannelNameToNuke.h Nuke's EXR i/o which accomodates files with large numbers of channels.
  • ExrChannelNameToNuke.cpp Nuke's EXR i/o which accomodates files with large numbers of channels.
  • exrReader.cpp Nuke's EXR i/o which accomodates files with large numbers of channels.
