| Methods inherited from TOP:
|
| cudaMemory(...)
| cudaMemory() -> CUDAMemory
| Copies the contents of the TOP to a newly allocated block of raw CUDA memory. The CUDA memory will be deallocated when the returned CUDAMemory object is deallocated. Ensure you keep a reference to the returned object around as long as you are using it.
|
| numpyArray(...)
| numpyArray(delayed=False, writable=False) -> numpy.array
| Returns the TOP image as a Python NumPy array. Note that since NumPy arrays are referenced by line first, pixels are addressed as [h, w]. Currently data will always be in floating point, regardless of what the texture data format is on the GPU.
|
| Args:
| delayed - (Keyword, Optional) If set to True, the download results will be delayed until the next call to numpyArray(), avoiding stalling the GPU waiting for the result immediately. This is useful to avoid long stalls that occur if immediately asking for the result. Each call with return the image that was 'current' on the previous call to numpyArray(). None will be returned if there isn't a result available. You should always check the return value against None to make sure you have a result. Call numpyArray() again, ideally on the next frame or later, to get the result. If you always need a result, you can call numpyArray() a second time in the event None is returned on the first call.
| writable - (Keyword, Optional) If set to True, the memory in the numpy array will be allocated in such a way that writes to it arn't slow. By default the memory the numpy array holds can be allocated in such a way that is very slow to write to. Note that in either case, writing to the numpy array will *not* change the data in the TOP.
|
| sample(...)
| sample(x=None,y=None,z=None,u=None,v=None,w=None) -> tuple(r,g,b,a)
| Returns a 4-tuple representing the color value at the specified texture location. One horizontal and one vertical component must be specified. Note that this is a very expensive operation currently. It will always stall the graphics pipeline if the TOP is currently queued to get updated, and then downloads the entire texture (not just the requested pixel). Use this for debugging and non-realtime workflows only.
|
| Args:
| x - (Keyword, Optional) The horizontal pixel coordinate to be sampled.
| y - (Keyword, Optional) The vertical pixel coordinate to be sampled.
| z - (Keyword, Optional) The depth pixel coordinate to be sampled. Available in builds 2022.23800 and later.
| u - (Keyword, Optional) The normalized horizontal coordinate to be sampled.
| v - (Keyword, Optional) The normalized vertical coordinate to be sampled.
| w - (Keyword, Optional) The normalized depth pixel coordinate to be sampled. Available in builds 2022.23800 and later.
|
| Example:
| r = n.sample(x=25,y=100)[0] #The red component at pixel 25,100.
| g = n.sample(u=0.5,v=0.5)[1] #The green component at the central location.
| b = n.sample(x=25,v=0.5)[2] #The blue 25 pixels across, and half way down.
|
| save(...)
| save(filepath, asynchronous=False, createFolders=False, quality=1.0, metadata=[]) -> filepath

|
| Args:
| filepath - (Optional) The path and filename to save to. If not given then a default filename will be used, and the file will be saved in the project.folder folder.
| aysnchronous - (Keyword, Optional) If True, the save will occur in another thread. The file may not be done writing at the time this function returns.
| createFolders - (Keyword, Optional) If True, folders listed in the path that don't exist will be created.
| quality - (Keyword, Optional) Specify the compression quality used. Values range from 0 (lowest quality, small size) to 1 (best quality, largest size).
| metadata - (Keyword, Optional) A list of string pairs that will be inserted into the file's metadata section. Any type of list structure is supported (dictionary, tuple, etc) as long as each metadata item has two entries (key & value). Note: Only supported on EXR files.
|
| Example:
| name = n.save() #save in default format with default name.
| n.save('picture.jpg')
| n.save('image.exr', metadata=[ ("my_key", "my_value"), ("author_name", "derivative") ] ); # save as .exr with custom metadata
|
| saveByteArray(...)
| saveByteArray(filetype, quality=1.0, metadata=[]) -> bytearray
| Saves the image to a bytearray object in the requested file format. Support file formats are: .tif, .tiff, .jpg, .jpeg, .bmp, .png, .exr and .dds. Returns the bytearray object. To get the raw image data use numpyArray() or cudaArray() instead.
|
| Args:
| filetype - (Optional) A string specifying the file type to save as. If not given the default file type '.tiff' will be used. Just the suffix of the string is used to determine the file type. E.g '.tiff', 'file.tiff', 'C:/Files/file.tiff' will all work. Suffix must include the period.
| quality - (Keyword, Optional) Specify the compression quality used. Values range from 0 (lowest quality, small size) to 1 (best quality, largest size).
| metadata - (Keyword, Optional) A list of string pairs that will be inserted into the file's metadata section. Any type of list structure is supported (dictionary, tuple, etc) as long as each metadata item has two entries (key & value). Note: Only supported on EXR files.
|
| Example:
| arr = n.saveByteArray() # save in default format.
| arr = n.saveByteArray('.jpg') # save as .jpg
| arr = n.saveByteArray('.exr', metadata=[ ("my_key", "my_value"), ("author_name", "derivative") ] ); # save as .exr with custom metadata

| Example:
| b = op.Videoplayer
| To list all Global OP Shortcuts:
|
| Example:
| for x in op:
| print(x)
| </blockquote>
|
| outputConnectors
| List of output connectors (on the right side) associated with this operator.
|
| outputs
| List of output operators (via right side connectors) from this operator.
|
| pages
| A list of all built-in pages.
|
| par
| An intermediate parameter collection object, from which a specific parameter can be found.
|
| Example:
| n.par.tx
| or
| n.par['tx']
|
| parGroup
| An intermediate parameter collection object, from which a specific parameter group can be found.
|
| Example:
| n.parGroup.t
| or
| n.parGroup['t']
|
| parent
| The Parent Shortcut object, for accessing parent components through indices or shortcuts.
| Note: a version of this method that searches relative to the current operator is also in the global td module.
|
| parent(n) → OP or None
| <blockquote>
| The nth parent of this operator. If n not specified, returns the parent. If n = 2, returns the parent of the parent, etc. If no parent exists at that level, None is returned.
|
| Args:
| n - (Optional) n is the number of levels up to climb. When n = 1 it will return the operator's parent.
|
| Example:
| p = parent(2) #grandfather
| </blockquote>
| parent.shortcut → OP
| <blockquote>
| A parent component specified with a shortcut. If no parent exists an exception is raised.
|
| Args:
| shortcut - Corresponds to the Parent Shortcut parameter specified in the target parent.
|
| Example:
| n = parent.Videoplayer
| See also Parent Shortcut for more examples.</blockquote>
|
| passive
| If true, operator will not cook before its access methods are called. To use a passive version of an operator n, use passive(n).
|
| path
| Full path to the operator.
|
| python
| Get or set parameter expression language as python.
|
| recursiveChildren
| Deprecated. Use op.numChildrenRecursive
|
| render
| Get or set Render Flag.
|
| replicator
| The replicatorCOMP that created this operator, if any.
|
| selected
| Get or set Selected Flag. This controls if the node is part of the network selection. (yellow box around it).
|
| showCustomOnly
| Get or set the Show Custom Only Flag which controls whether or not non custom parameters are display in parameter dialogs.
|
| showDocked
| Get or set Show Docked Flag. This controls whether this node is visible or hidden when it is docked to another node.
|
| storage
| Storage is dictionary associated with this operator. Values stored in this dictionary are persistent, and saved with the operator. The dictionary attribute is read only, but not its contents. Its contents may be manipulated directly with methods such as OP.fetch() or OP.store() described below, or examined with an Examine DAT.
|
| tags
| Get or set a set of user defined strings. Tags can be searched using OP.findChildren() and the OP Find DAT.
| The set is a regular python set, and can be accessed accordingly:
|
| Example:
| n.tags = ['effect', 'image filter']
| n.tags.add('darken')
|
| time
| Time Component that defines the operator's time reference.
|
| totalCooks
| Number of times the operator has cooked.
|
| valid
| True if the referenced operator currently exists, False if it has been deleted.
|
| viewer
| Get or set Viewer Flag.
|
| warning
| (Deprecated.) Get or set the warning message associated with this OP.
