-------------------------------------------------------------------------------- /doc/ja_JP/usage.md: -------------------------------------------------------------------------------- 1 | # コマンドラインオプションの説明 2 | 3 | ## 入出力 4 | 5 | ### 入力 6 | 7 | - `-i input.avif`（必須） 8 | 9 | ### 出力 10 | 11 | - `-o output.png`（必須） 12 | 13 | ### Alpha/Depth画像の展開 14 | 15 | - `--extract-alpha ` 16 | - `--extract-depth ` 17 | 18 | 付与されているalpha/depthの画像を別ファイルにデコードして保存する。 19 | 20 | このオプションでalphaを展開しても、`-o `で指定したファイルには引き続きalphaは適用される。 21 | 22 | ## マルチスレッド 23 | 24 | ### 利用スレッド数 25 | 26 | - `--threads ` 27 | - 初期値：論理コア数（`nproc`コマンドで確認可能） 28 | 29 | 注意点： 30 | 31 | - `--threads 0` の場合、メインスレッドのみでデコードする。 32 | - `--threads 1` の場合、メインスレッドとは別にもう1つスレッドが建ち、一応多少早くなる。 33 |
