tf.image.encode_png(image, compression=None, name=None)
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: A Tensor. Must be one of the following types: uint8, uint1
