Photograph of a computer monitor showing Python source code written in a text editor interface. The code appears to be related to frame parameter handling and interpolation using numerical values stored in Pandas Series objects. The upper portion contains function definitions and conditional statements. A highlighted segment shows:
frames[frame] = param
if frames == {} and len(string) != 0:
raise RuntimeError("Key Frame string not correctly ...")
return frames
This block assigns a parameter to a specific frame, validates input conditions, and raises an exception if a keyframe string is incorrectly formatted.
Below, a function definition is visible:
def get_inbetweens(key_frames, integer_values):
"""Return a dict with frame numbers as keys and a parameter ..."""
The function docstring explains its purpose: generating an output dictionary or Pandas Series that interpolates parameter values across frames. It notes that if values are missing for a frame, they are derived from surrounding values. The documentation specifies that values at the start and end are extended outward if absent, while intermediate frames are interpolated between known keyframes.
The parameter section specifies expected inputs:
key_frames: dictionary with integer frame numbers as keys and corresponding numerical values.
integer_values: optional list of frames for which interpolated values are to be computed.
The return type is given as a Pandas Series with frame numbers as the index and float values representing the interpolated parameters.
Example usage is partially visible:
>>> key_frames = {0: 0, 10: 1}
>>> get_inbetweens(key_frames, (0, 3, 9, 10))
Output shown includes interpolated floating-point values (e.g., 0.3, 0.9, 1.0) calculated linearly between defined keyframes.
The visual context indicates an environment for coding and debugging numerical interpolation functions, with emphasis on animation, frame-based computation, or procedural parameter automation. The code suggests application in a system requiring smooth transitions between discrete keyframe values, potentially animation pipelines, simulation systems, or generative media frameworks.
