tensorflow:: ops:: EncodeJpeg

JPEG-encode an image.

Summary

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.

Args:

• scope: A Scope object
• image: 3-D with shape [height, width, channels] .

Optional attributes (see Attrs ):

• format: Per pixel image format.
• quality: Quality of the compression from 0 to 100 (higher is better and slower).
• progressive: If True, create a JPEG that loads progressively (coarse to fine).
• optimize_size: If True, spend CPU/RAM to reduce size with no quality change.
• chroma_downsampling: See http://en.wikipedia.org/wiki/Chroma_subsampling .
• density_unit: Unit used to specify x_density and y_density : pixels per inch ( 'in' ) or centimeter ( 'cm' ).
• x_density: Horizontal pixels per density unit.
• y_density: Vertical pixels per density unit.
• xmp_metadata: If not empty, embed this XMP metadata in the image header.

Returns:

• Output : 0-D. JPEG-encoded image.
