Given a declarative specification, creates a callable with the following signature: ``callback(x_range, y_range, width, height)`` where ``x_range`` and ``y_range`` form the bounding box on the viewport, and ``width`` and ``height`` specify the output image dimensions. Parameters ---------- df : pandas.DataFrame, dask.DataFrame glyph : Glyph The glyph to bin by. agg : Reduction, optional The reduction to compute per-pixel. Default is ``count()``. transform_fn : callable, optional A callable that takes the computed aggregate as an argument, and returns another aggregate. This can be used to do preprocessing before passing to the ``color_fn`` function. color_fn : callable, optional A callable that takes the output of ``tranform_fn``, and returns an ``Image`` object. Default is ``shade``. spread_fn : callable, optional A callable that takes the output of ``color_fn``, and returns another ``Image`` object. Default is ``dynspread``. height_scale: float, optional Factor by which to scale the provided height width_scale: float, optional Factor by which to scale the provided width g?c t||_||_||_||_||_||_||_||_y)N)dfglyphagg transform_fncolor_fn spread_fn width_scale height_scale) selfr r rrrrrrs 3lib/python3.12/site-packages/datashader/pipeline.py__init__zPipeline.__init__+s?
