EncodePng

public final class EncodePng

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.

Constants

Constant Value: "EncodePng"

Public Methods

public Output<TString> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static EncodePng.Options compression (Long compression)

Parameters
compression Compression level.

public Output<TString> contents ()

0-D. PNG-encoded image.

public static EncodePng create (Scope scope, Operand<? extends TNumber> image, Options... options)

Factory method to create a class wrapping a new EncodePng operation.

Parameters
scope current scope
image 3-D with shape `[height, width, channels]`.
options carries optional attributes values
Returns
  • a new instance of EncodePng
