フォント指定でのPNG出力で出力エラーとなる #1

Open tk0miya opened 6 years ago

tk0miya commented 6 years ago

フォント指定でのPNG出力で出力エラーとなる現象がありましたので報告いたします。 ちなみに、blogにてコメントを頂戴した物です。

==== 状況 ==== redmineのWiki External Filter Plugin経由で実行しました。

==== コード ====

{
   サイトトップ -> ログイン画面 -> 情報一覧画面;
   サイトトップ -> 会員登録入力画面 -> 会員登録確認画面 -> 会員登録完了画面 -> サンキューメール;
   サンキューメール[shape = "mail"];
}

==== 実行コマンド ====

/usr/bin/nwdiag -Tpng  -f /usr/share/fonts/japanese/TrueType/sazanami-gothic.ttf -a -o/dev/stdout /dev/stdin

===== 備考 ===== フォントを指定すると本現象が発生する。 フォント指定をしない場合は本現象は発生しませんでした。

==== バージョン情報 ==== Linux MACHINENAME 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:10:56 EDT 2011 i686 i686 i386 GNU/Linux CentOS release 5.6 (Final)

The issue should be treated more general. The current implementation seems to follow a kind of 'stack-based' assignments of method calls and returns. I have not found any way how to specify what instance activation a given method call should be linked to. GraphViz uses a notion of ports. What about to extend the syntax in similar way, i.e. to enable a use of activity labels extending instance labels? For example: { A -> C:0; B -> C:1; A <-- C:0; B <-- C:1; } For example, this would enable to diagram a number of threads under one instance (like HTTP pipelining, etc in my case :-)).
