PNG-encode an image.
tf.raw_ops.EncodePng( image, compression=-1, name=None )
image
is a 3-D uint8 or uint16 Tensor of shape [height, width, channels]
where channels
is:
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.
