tensorflow::ops::DecodePng

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].
