pymovements.gaze.GazeDataFrame.deg2pix#

GazeDataFrame.deg2pix(pixel_origin: str = 'upper left', position_column: str = 'position', pixel_column: str = 'pixel') → None#

Compute gaze positions in pixel position coordinates from degrees of visual angle.

This method requires a properly initialized experiment attribute.

After success, the gaze dataframe is extended by the resulting dva position columns.

Parameters:

pixel_origin (str) – The desired location of the pixel origin. (default: ‘upper left’) Supported values: center, upper left.
position_column (str) – The input position column name. (default: ‘position’)
pixel_column (str) – The output pixel column name. (default: ‘pixel’)

Raises:

AttributeError – If gaze is None or there are no gaze dataframes present in the gaze attribute, or if experiment is None.
