PNG-encode an image.
tf.image.encode_png(
image, compression=-1, name=None
)
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.
