その３７の補足：”Inkscapeから素材を作成して、Expression Blendで扱うまで”の罠って？

やまきさんにツッコミを頂いたので補足します。

結論からいうと、このxamlはBlendにインポート機能が無かった時代に作られたWPF向けのXAMLです。

具体的に中を見てみましょう。

Expression Blendにaiでインポートしたペンギンのxamlです。

素直にCanvasでくくられているだけでなく、ViewBoxでもくくられています。
またPath.Dataも入れ子で書かれています。
ではこのxamlをコピーして、既存のxamlファイルにペーストしてどうなるか試してみましょう。

無効なXAMLといわれました。

エラーを見るとFiguresで引っかかっているようです。

一応SilverlightにもFiguresがありますが、"m ~~~~ z"でスタートポイントとエンドポイントを設定する書き方はできません。
http://msdn.microsoft.com/ja-jp/library/bb980098(v=vs.95).aspx
この書き方はWPFなら可能のようです。
