#include <image_ops.h>

Optional attribute setters for DecodeJpeg.

Summary

Public attributes
`acceptable_fraction_ = 1.0f`	`float`
`channels_ = 0`	`int64`
`dct_method_ = ""`	`StringPiece`
`fancy_upscaling_ = true`	`bool`
`ratio_ = 1`	`int64`
`try_recover_truncated_ = false`	`bool`

Public functions
`AcceptableFraction(float x)`	`TF_MUST_USE_RESULT Attrs` The minimum required fraction of lines before a truncated input is accepted.
`Channels(int64 x)`	`TF_MUST_USE_RESULT Attrs` Number of color channels for the decoded image.
`DctMethod(StringPiece x)`	`TF_MUST_USE_RESULT Attrs` string specifying a hint about the algorithm used for decompression.
`FancyUpscaling(bool x)`	`TF_MUST_USE_RESULT Attrs` If true use a slower but nicer upscaling of the chroma planes (yuv420/422 only).
`Ratio(int64 x)`	`TF_MUST_USE_RESULT Attrs` Downscaling ratio.
`TryRecoverTruncated(bool x)`	`TF_MUST_USE_RESULT Attrs` If true try to recover an image from truncated input.

Public attributes

acceptable_fraction_

float tensorflow::ops::DecodeJpeg::Attrs::acceptable_fraction_ = 1.0f

channels_

int64 tensorflow::ops::DecodeJpeg::Attrs::channels_ = 0

dct_method_

StringPiece tensorflow::ops::DecodeJpeg::Attrs::dct_method_ = ""

fancy_upscaling_

bool tensorflow::ops::DecodeJpeg::Attrs::fancy_upscaling_ = true

ratio_

int64 tensorflow::ops::DecodeJpeg::Attrs::ratio_ = 1

try_recover_truncated_

bool tensorflow::ops::DecodeJpeg::Attrs::try_recover_truncated_ = false

Public functions

AcceptableFraction

TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::AcceptableFraction(
  float x
)

The minimum required fraction of lines before a truncated input is accepted.

Defaults to 1

Channels

TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::Channels(
  int64 x
)

Number of color channels for the decoded image.

Defaults to 0

DctMethod

TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::DctMethod(
  StringPiece x
)

string specifying a hint about the algorithm used for decompression.

Defaults to "" which maps to a system-specific default. Currently valid values are ["INTEGER_FAST", "INTEGER_ACCURATE"]. The hint may be ignored (e.g., the internal jpeg library changes to a version that does not have that specific option.)

Defaults to ""

FancyUpscaling

TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::FancyUpscaling(
  bool x
)

If true use a slower but nicer upscaling of the chroma planes (yuv420/422 only).

Defaults to true

Ratio

TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::Ratio(
  int64 x
)

Downscaling ratio.

Defaults to 1

TryRecoverTruncated

TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::TryRecoverTruncated(
  bool x
)

If true try to recover an image from truncated input.

Defaults to false
