Bases: core.Hiero.Python.SubTrackItem
Class for objects that can hold multiple stroke and/or text elements to provide annotation functionality.
Annotation is derived from SubTrackItem and thus Annotation objects can be placed and trimmed on VideoTrack
subtracks. Strokes and/or text can be added to an annotation by creating AnnotationStroke and/or AnnotationText
objects and using addElement().
self.addElement() -> Adds the specified AnnotationElement, which should be an instance of an AnnotationElement sub-class, i.e. either
an AnnotationStroke or an AnnotationText object.
@return: If there was no error, returns the added element.
self.elements() -> returns a tuple with all of the elements contained in this annotation.
@return: tuple of hiero.core.Element sub-class objects
self.toString() -> returns a description of the object. Equivalent to str(object).
@return: string
Bases: Shiboken.Object
Base class for types of elements that may be added to an Annotation.
This class shold not be used directly and AnnotationElement objects should not be created.
self.color() -> returns a tuple containing the color for this annotation element in the form (red, green, blue, alpha),
with the components represented as floating point values in the range [0, 1].
@return: tuple of (red, green, blue, alpha)
self.setColor() -> None
Sets the color and alpha of the element.
Each component must be a floating point value in the range [0, 1].
@param red: The new red component.
@param green: The new green component.
@param blue: The new blue component.
@param alpha: The new alpha component.
self.toString() -> string
Returns a description of the object. Equivalent to str(object).
@return: A string describing the object.
Bases: core.Hiero.Python.AnnotationElement
A class, derived from AnnotationElement, storing a set of 2d points to represent a single stroke
within an annotation.
self.points -> Returns a variable tuple containing the 2d points forming the stroke. Each point is
represented as a 2 component tuple, with the x and y components of the point as floating point values.
@return: tuple of 2 component tuples, each of the form (x, y)
self.setPoints -> Sets the points that make up this stroke, replacing any points the stroke already had.
The points must be specified as a list (not tuple) of 2d points, each point being a 2 component tuple of
floats or integers, e.g. [(100, 200), (123.456, 300)].

@return: string
Bases: core.Hiero.Python.AnnotationElement

Base class to be derived from in order to populate an ExportStructureViewer widget, such as the one used in the Export dialog box. IExportStructure objects provides access to a root node, which has to be an object derived from IExportStructureElement, which the ExportStructureViewer widget then uses to determine the tree structure to display to the user. For an example of how to derive from this class, see Plugins/site-packages/hiero/core/FnExportStructure.py. For an example use of a derived IExportStructure object, see Plugins/site-packages/hiero/exporters/FnShotProcessor.py. It will often be more than sufficient to just use an ExportStructure2 object, instead of subclassing IExportStructure directly.

Used to store name/value pairs that can be resolved in strings. Example: Assuming the resolve table has an item “{filename}” that resolves to example.mov, Then calling resolveTable.resolve(taskObject, “someprefix_{filename}”) will return “someprefix_example.mov” To use, create an object, call addResolver on it with whatever key/value pairs you want, and then you can call resolve on the object to resolve a string. You can also merge two ResolveTable objects, replacing existing key’s with those in the ResolveTable passed in. And you can use functions to do the resolve. These take one parameter, the task that the resolve is applying to. For an example of how to use this, see FnExporterBase.py.

This is a variation on the Clip.addToNukeScript() method that remaps the Read frame range to the range of the this TrackItem rather than the Clip’s range. TrackItem retimes and reverses are applied via Retime and OFlow nodes if needed.

This means timing can be set in the original source range and adding channels, etc won’t affect frames outside the cut length.

Execute the callable ‘call’ with optional arguments ‘args’ and named arguments ‘kwargs’ in the main thread and return immediately. Note that this method expects a single item for args or a tuple, and a dictionary for kwargs. It will not accept anything else.
Examples of how to use this method (that work):
executeInMainThread(someMethod, “First positional parameter”) executeInMainThread(someMethod, “First positional parameter”, {‘kwArg0’: “arg0”}) executeInMainThread(someMethod, (“First positional parameter”, “kwArg0 passed as positional parameter”)) executeInMainThread(someMethod, (“First positional parameter”, “kwArg0 passed as positional parameter”), {‘kwArg1’: “arg1 as well”}) executeInMainThread(someMethod, “First positional parameter”, {‘kwArg1’: “arg1”})
An example of what won’t work:
executeInMainThread(someMethod, “First positional parameter”, “Second positional parameter”)
The above fails because the second parameter to executeInMainThread must be a dictionary.
Execute the callable ‘call’ with optional arguments ‘args’ and named arguments ‘kwargs’ in the main thread and wait for the result. Note that this method expects a single item for args or a tuple, and a dictionary for kwargs. It will not accept anything else.

hiero.core.filenameList(directory, splitSequences, returnDirectories, returnHiddenFiles) -> Returns a list of strings representing the items found in the specified directory, putting image sequences together as one element.
@param directory: path to the directory to query
@param splitSequences: optional, defaults to False. If set to True, then splits broken image sequences up. Otherwise, broken sequences create only one entry in the returned list
@param returnDirectories: optional, defaults to True. If set to True, sub directories will be included in the returned list
@param returnHiddenFiles: optional, defaults to True. If set to True, hidden/system files will be returned in the list
For a directory with the following items: item1.txt item2.txt quicktime.mov highres1.dpx
You’d get a tuple with the same list of items (txt files are recognized as not being image sequences).
You’d get a tuple with: (“quicktime.mov”, “highres#.dpx 1-4”)
Note the missing 3 in the above list. If you set splitSequences to False, you’d get: (“highres#.dpx 1-5”)
If instead you set splitSequences to True, you’d get: (“highres#.dpx 1-3”, “highres#.dpx 4-5”)
You’d get a tuple like this: (“highres###.dpx 1-5”)
You’d get this: (“highres#.dpx 99-100”)
In the above example, the sequence number crosses over from 2 digits to 3, so it is treated as one and the number of hashes (#) is put to 1, which means the number is wild.
You’d get this: (“highres###.dpx 99-100”)
Note that in this last example, the 99 is prefixed with 0.
findItemsInProject -> Returns all items in a Project’s clipsBin. User can filter by a specific type(s) or by partial name, and optionally print a verbose log to the output window. Takes up to 4 keyword arguments : Project object, a string, a type or an array of strings for filter type, partial name of item, and a bool to enable/disable verbose mode Returns an array of items. Note: to find Tags in a Project, use the findProjectTags method.

@return: Project object
hiero.core.openProject(path) Opens the project found at the specified path. Must be called on the main thread. Throws an exception on failure. @param path: Path to the project file (*.hrox). @return: Opened project.
openProjectStartup(path -> for internal use only, hiero.core.openProject(path) should be used instead.
@return: Project object

@param projectTypes: optional; one of Project.kAllProjects, Project.kUserProjects, Project.kStartupProjects

quit() -> shuts down Hiero, without saving any existing projects. Safer than calling sys.exit(), which doesn’t always clean up properly and can cause Hiero to crash. This version sets the exit code of the Hiero process to 0.
Note that this must be the last line in a script.
quit(exitCode) -> same as the first version of this method, except that this one sets the exit code of the process to the exitCode variable.
