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:

• 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	A Tensor. Must be one of the following types: uint8, uint16. 3-D with shape [height, width, channels].
compression	An optional int. Defaults to -1. Compression level.
name	A name for the operation (optional).

Returns
A Tensor of type string.
