class hiero.core.Annotation

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().

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.

elements

self.elements() -> returns a tuple with all of the elements contained in this annotation.

@return: tuple of hiero.core.Element sub-class objects

toString

self.toString() -> returns a description of the object. Equivalent to str(object).

@return: 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.

Represents a specific item on a Track. Can also be created using the createTrackItem method on VideoTrack and AudioTrack objects. Can be converted to a MediaSource object if isSource() returns True, or a Sequence object if isSequence() returns True.

Note that the version functions don’t cause a scan of any directories for other versions of media and will only skip to versions that have already been discovered. For an example of how to do that, see Plugins/site-packages/hiero/ui/ScanForVersions.py.

For an example of how to implement custom versioning scheme, see Plugins/site-packages/hiero/core/versioning_example.py.

@return: string

trackIndex
hiero.core.addPathRemap()

addPathRemap(windowsPathPrefix -> adds to the table of file path remapping prefixes that Hiero maintains. Pairs of path prefixes added to this table will be used to convert paths between Windows, OSX and Linux. When on Windows, Hiero will replace any Linux or OSX prefixes found with the corresponding Windows prefix. On OSX, Hiero will search for the Windows and Linux path prefixes and replace them with the corresponding OSX prefix. The same applies for OSX/Windows prefixes being replaced on Linux. These can also be configured through the user interface in the General tab of the Preferences dialog.

@param windowsPathPrefix: string

@param osxPathPrefix: string

@param linuxPathPrefix: string

@return: None

hiero.core.addPluginPath()

addPluginPath(pluginPath) -> adds a new path to the list of plugin paths searched for Python plugins (in Python/Startup and Python/StartupUI folders). The user’s .nuke folder will be the first in this list.

addPluginPath(pluginPath -> the same as above, except that the index specifies which item in the list of paths to place the new one before.

@param pluginPath: the new path to add

@param index: optional; if not specified or negative, the new path will be added to the end of the list

hiero.core.closeAllProjects()

hiero.core.closeProject() -> closes all of the existing projects without saving.

hiero.core.closeProject(bool dontSave) -> same as above, but if the parameter is set to false, unsaved projects will cause Hiero to popup a dialog for each unsaved project, asking the user if they’d like to save.

@param dontSave: True or False

hiero.core.conformer()

conformer() -> returns an interface for setting the conforming options.

@return: a Conformer object

hiero.core.defaultFrameRates()

hiero.core.defaultFrameRates() -> returns the list of frame rates displayed in Hiero’s user interface.

@return: tuple of floats

hiero.core.executeInMainThread(call, *args, **kwargs)

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):

def someMethod(firstParameter, kwArg0=None, kwArg1=None)
print firstParameter

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.

hiero.core.executeInMainThreadWithResult(call, *args, **kwargs)

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.

Examples of how to use this method (that work):

def someMethod(firstParameter, kwArg0=None, kwArg1=None)
print firstParameter return kwArg1

result = executeInMainThreadWithResult(someMethod, “First positional parameter”) result = executeInMainThreadWithResult(someMethod, “First positional parameter”, {‘kwArg0’: “arg0”}) result = executeInMainThreadWithResult(someMethod, (“First positional parameter”, “kwArg0 passed as positional parameter”)) result = executeInMainThreadWithResult(someMethod, (“First positional parameter”, “kwArg0 passed as positional parameter”), {‘kwArg1’: “arg1 as well”}) result = executeInMainThreadWithResult(someMethod, “First positional parameter”, {‘kwArg1’: “arg1”})

An example of what won’t work:

result = executeInMainThreadWithResult(someMethod, “First positional parameter”, “Second positional parameter”)

The above fails because the second parameter to executeInMainThread must be a dictionary.

hiero.core.filenameList(directory, splitSequences=False, returnDirectories=True, returnHiddenFiles=True)

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).

With a directory with the following items:
  • quicktime.mov
  • highres1.dpx
  • highres2.dpx
  • highres3.dpx
  • highres4.dpx
  • highres5.dpx

You’d get a tuple with: (“quicktime.mov”, “highres#.dpx 1-4”)

If you had the following in a directory:
  • highres1.dpx
  • highres2.dpx
  • highres4.dpx
  • highres5.dpx

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”)

If you had a directory with this:
  • highres001.dpx
  • highres002.dpx
  • highres003.dpx
  • highres004.dpx
  • highres005.dpx

You’d get a tuple like this: (“highres###.dpx 1-5”)

If you had a directory with this:
  • highres99.dpx
  • highres100.dpx

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.

If instead you had a directory with this:
  • highres099.dpx
  • highres100.dpx

You’d get this: (“highres###.dpx 99-100”)

Note that in this last example, the 99 is prefixed with 0.
