tf.image.encode_png(
image,
compression=-1,
name=None
)
Defined in generated file: tensorflow/python/ops/gen_image_ops.py
.
PNG-encode an image.
image
is a 3-D uint8 or uint16 Tensor of shape [height, width, channels]
where channels
is:
- 1: for grayscale.
- 2: for grayscale + alpha.
- 3: for RGB.
- 4: for RGBA.
The ZLIB compression level, compression
, can be -1 for the PNG-encoder
default or a value from 0 to 9. 9 is the highest compression level, generating
the smallest output, but is slower.
Args:
image
: ATensor
. Must be one of the following types:uint8
,uint16
. 3-D with shape[height, width, channels]
.compression
: An optionalint
. Defaults to-1
. Compression level.name
: A name for the operation (optional).
Returns:
A Tensor
of type string
.
