tensorflow::ops::EncodeJpeg

#include <image_ops.h>

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. Thechannelsdimension ofimagemust be 1. *rgb: Output an RGB JPEG image. Thechannelsdimension ofimage` 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.

Arguments:

• 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.
