tensorflow:: ops:: DecodePng

#include <image_ops.h>

Decode a PNG-encoded image to a uint8 or uint16 tensor.

Summary

The attr channels indicates the desired number of color channels for the decoded image.

Accepted values are:

  • 0: Use the number of channels in the PNG-encoded image.
  • 1: output a grayscale image.
  • 3: output an RGB image.
  • 4: output an RGBA image.

If needed, the PNG-encoded image is transformed to match the requested number of color channels.

This op also supports decoding JPEGs and non-animated GIFs since the interface is the same, though it is cleaner to use tf.io.decode_image .

Args:

  • scope: A Scope object
  • contents: 0-D. The PNG-encoded image.

Optional attributes (see Attrs ):

  • channels: Number of color channels for the decoded image.

Returns:

  • Output : 3-D with shape [height, width, channels] .
