enum | ExecMode { WriteOne, WriteAny, WriteMany } |
This is a base class for a file writer.
All the work is done by the various subclasses of Writer. Write just chooses what subclass to instantiate and returns the output from it, and correctly destroys and instantiates new ones as needed.
Calling Iop::execute() initiates writing the file.
|
overrideprotectedvirtual |
Modify the info to show what is actually written to the file. This assumes the normal behavior that the file clips to the format and writes the channels packed together as the first N channels. It assumes that if you have set the mask to "all" then you are writing a file format that preserves channel names.

This is not true if the input is not connected (to avoid writing black frames but without producing an error) and is not true if "reading" is turned on.

Write the current frame. The Writer object is created if it does not exist, and then execute() is called on it. If the writer does not claim to be a movie file, finish() is called on it.
Implements DD::Image::Executable.

Calls finish() on the Writer if it is writing a movie file. If reading is turned on it acts like user hit the Reload button.
Reimplemented from DD::Image::Executable.
References DD::Image::Writer::finish(), and DD::Image::Writer::movie().

overridevirtual |
Returns WriteMany if the Writer object asks for more than one in Writer::split_input(), indicating that (most likely) more than one view is wanted. Returns WriteOne otherwise, indicating it is a waste of time to call this with different views. Nuke will detect if the filename changes when the view changes and will call this multiple times with different filenames, otherwise complain if the user asks for more than one view to execute.

Return the type of file this will write. This is set by set_file_type() or set_file_type_from_filename() or by validate() if neither of these is done. This is actually the null-sepearted list of names from the DD::Image::Writer::Description object.
Implements DD::Image::FileOp.
Referenced by set_file_type().
bool Write::set_file_type | ( | const char * | name | ) |
Set the type of file the Writer will write. The type is a string like "cin" or "jpeg". Returns true if the new type is different than the previous one. Notice that if the type changes all settings on Writer-specific knobs are lost.
If this type is not found or is zero then file_type() is set to zero. If the node is then executed it will attempt to figure out the type from the filename, and if that fails it will cause an error.
file_types() returns a list of available names. You may also be able to set other names like "sgi16" that are not in this list, these typically initialize some knobs to non-default values.

Referenced by set_file_type_from_filename().
bool Write::set_file_type_from_filename | ( | Knob * | knob = nullptr | ) |
If the filename has "name:" near the start, try using that to set the file type. If that fails, try using the file extension. This is automatically done by execute() and validate() if this or set_file_type() has not been called.
References DD::Image::Knob::get_text(), DD::Image::plugin_error(), and set_file_type().

Does Writer::depth(). Current implementation returns the number of channels turned on in the selector and in the input.

Use this to set a watermark iop to be applied immediately before all writes, without showing it on the DAG. There is no function to turn this off again, as there should be no need.
