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. The
channelsdimension of
imagemust be 1. *
rgb: Output an RGB JPEG image. The
channelsdimension 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
:
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
andy_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.
