Ringkasan
Fungsi publik |
|---|
AcceptableFraction (float x) | Fraksi baris minimum yang diperlukan sebelum masukan terpotong diterima. |
Channels (int64 x) | Jumlah saluran warna untuk gambar yang didekodekan. |
DctMethod (StringPiece x) | string yang menentukan petunjuk tentang algoritma yang digunakan untuk dekompresi. |
FancyUpscaling (bool x) | Jika benar, gunakan peningkatan bidang kroma yang lebih lambat namun lebih bagus (khusus yuv420/422). |
Ratio (int64 x) | Rasio penurunan. |
TryRecoverTruncated (bool x) | Jika benar, coba pulihkan gambar dari masukan yang terpotong. |

Fungsi publik
Pecahan yang Dapat Diterima
TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::AcceptableFraction(
float x
)
Fraksi baris minimum yang diperlukan sebelum masukan terpotong diterima.
Defaultnya adalah 1
Saluran
TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::Channels(
int64 x
)
Jumlah saluran warna untuk gambar yang didekodekan.
Defaultnya adalah 0
Metode Dct
TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::DctMethod(
StringPiece x
)
string yang menentukan petunjuk tentang algoritma yang digunakan untuk dekompresi.
Defaultnya adalah "" yang memetakan ke default khusus sistem. Nilai yang valid saat ini adalah ["INTEGER_FAST", "INTEGER_ACCURATE"]. Petunjuknya mungkin diabaikan (misalnya, perpustakaan jpeg internal berubah ke versi yang tidak memiliki opsi spesifik tersebut.)
Defaultnya adalah ""
Peningkatan Mewah
TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::FancyUpscaling(
bool x
)
Jika benar, gunakan peningkatan bidang kroma yang lebih lambat namun lebih bagus (khusus yuv420/422).
Defaultnya adalah benar
Perbandingan
TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::Ratio(
int64 x
)
Rasio penurunan.
Defaultnya adalah 1
Coba Pulihkan Terpotong
TF_MUST_USE_RESULT Attrs tensorflow::ops::DecodeJpeg::Attrs::TryRecoverTruncated(
bool x
)
Jika benar, coba pulihkan gambar dari masukan yang terpotong.
Defaultnya salah
