tf.raw_ops.DecodePng
Stay organized with collections
Save and categorize content based on your preferences.
Decode a PNG-encoded image to a uint8 or uint16 tensor.
tf.raw_ops.DecodePng(
contents,
channels=0,
dtype=tf.dtypes.uint8
,
name=None
)
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
.
