Function for decode_bmp, decode_gif, decode_jpeg, and decode_png.
tf.raw_ops.DecodeImage(
contents, channels=0, dtype=tf.dtypes.uint8, expand_animations=True, name=None
)
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.
Args | |
|---|---|
contents
|
A Tensor of type string. 0-D. The encoded image bytes.
|
channels
|
An optional int. Defaults to 0.
Number of color channels for the decoded image.
|
dtype
|
An optional tf.DType from: tf.uint8, tf.uint16, tf.float32. Defaults to tf.uint8.
The desired DType of the returned Tensor.
|
expand_animations
|
An optional bool. Defaults to True.
Controls the output shape of the returned op. 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.
|
name
|
A name for the operation (optional). |
Returns | |
|---|---|
A Tensor of type dtype.
