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].
