Detects whether an image is a BMP, GIF, JPEG, or PNG, and performs the
appropriate operation to convert the input bytes string into a Tensor
of type dtype.
0-D string. The encoded image bytes.
An optional int. Defaults to 0. Number of color channels for
the decoded image.
The desired DType of the returned Tensor.
A name for the operation (optional)
Controls the shape of the returned op's output. If
True, the returned op will produce a 3-D tensor for PNG, JPEG, and BMP
files; and a 4-D tensor for all GIFs, whether animated or not. If,
False, the returned op will produce a 3-D tensor for all file types and
will truncate animated GIFs to the first frame.
Tensor with type dtype and a 3- or 4-dimensional shape, depending on
the file type and the value of the expand_animations parameter.
