Decode a PNG-encoded image to a uint8 or uint16 tensor.
The attr `channels` indicates the desired number of color channels for the decoded image.
Accepted values are:
- 0: Use the number of channels in the PNG-encoded image.
- 1: output a grayscale image.
- 3: output an RGB image.
- 4: output an RGBA image.
This op also supports decoding JPEGs and non-animated GIFs since the interface
is the same, though it is cleaner to use tf.io.decode_image
.

Public Methods
public Output<T> asOutput ()
Returns the symbolic handle of the tensor.
Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.
public static DecodePng.Options channels (Long channels)
Parameters
channels | Number of color channels for the decoded image. |

Parameters
scope | current scope |
---|---|
contents | 0-D. The PNG-encoded image. |
