Hello Raspberry Pi!

ImageMagick で艦これの改装画面を自動アレンジ

https://lh3.googleusercontent.com/-cXo1g_TKFC8/VmLnwv-6pgI/AAAAAAAANKQ/Jyh_YCQcdp0/d-h-Ic42/0000.png

久しぶりに ImageMagick を弄ってて反射効果の復習がしたかったので艦これ艦隊これくしょん)の改装画面をキャプチャーしたものを convert 1回でアレンジするスクリプトを書いてみた。

必要なものは以下の画像6枚。艦これの画面は正確にクロップすれば800×480のはず。これは GIMP を使うと Autocrop Image が使えるので簡単。

フォントは Font Squirrel で手に入る Boycott を使用。

あとは以下のスクリプトの引数に画像ファイルをつけて実行するだけ。工程を何度かに分ければもう少しわかりやすいスクリプトになるけど1回で済ませたかったので若干カオスな状態に…。

原寸大だとこんな感じ。

横に長過ぎるからちょっとレイアウト変えたほうがいいかなぁ…。


左角の切り抜き加工を追加した。座標指定で切り抜かないで、マスクを作成して切り抜くことにした。透明化を維持したまま反射部分を作るのが複雑…。
