(Python only)

Fetches pixels from an image asset.

Returns: The pixels as raw image data.

paramsObjectAn object containing parameters with the following possible values:
assetId - The asset ID for which to get pixels. Must be an image asset.
fileFormat - The resulting file format. Defaults to png. See ImageFileFormat for the available formats. There are additional formats that convert the downloaded object to a Python data object. These include: NUMPY_NDARRAY, which converts to a structured NumPy array.
grid - Parameters describing the pixel grid in which to fetch data. Defaults to the native pixel grid of the data.
region - If present, the region of data to return, specified as a GeoJSON geometry object (see RFC 7946).
bandIds - If present, specifies a specific set of bands from which to get pixels.
visualizationOptions - If present, a set of visualization options to apply to produce an 8-bit RGB visualization of the data, rather than returning the raw data.
