tf.io.encode_jpeg

JPEG-encode an image.

image is a 3-D uint8 Tensor of shape [height, width, channels].

The attr format can be used to override the color format of the encoded output. Values can be:

  • '': Use a default format based on the number of channels in the image.
  • grayscale: Output a grayscale JPEG image. The channels dimension of image must be 1.
  • rgb: Output an RGB JPEG image. The channels dimension of image must be 3.

If format is not specified or is the empty string, a default format is picked in function of the number of channels in image:

  • 1: Output a grayscale image.
  • 3: Output an RGB image.

image A Tensor of type uint8. 3-D with shape [height, width, channels].
format An optional string from: "", "grayscale", "rgb". Defaults to "". Per pixel image format.
quality An optional int. Defaults to
