 タブ譜を描いただけですが、ここではVexFlowのタブ譜の技術は使わず、通常の五線譜を二つ重ねているだけです。線が重なると少し汚くなるので、必要最小限になるよう。重ねる五線譜の一つは、10ピクセル上にずらした上で、一番上の線だけを描いています。小節線の長さは調節できないので、一部重なっています。これで6線50ピクセルの幅のタブ譜になります。TAB記号は自作のフォントを前の記事でもやった方法で追加しています。
 
 
 ベースのタブ譜は逆に4線譜にしないといけないので、ひとつ削っています。ただし、このままだと小節線が飛び出してしまうので、VexFlowの機能の小節線は描かないようにしました。そして、あらたに作った関数で、30ピクセルの小節線を描くようにしています。なので、この先、二重線にしたり、リピート記号を描いたりする必要が出てきたら、また関数はちょこっと変えていかないといけないのだと思います。繰り返し記号など全部の小節線の種類を網羅しないといけないですね。ベースタブ譜は公式でも対応できないので、これくらいの苦労はしかたないですね。
 
 
*insertBaseEndBarPathToSVG(Stave)
 
 
 引数のStaveオブジェクトが示す小節に対して30ピクセルの縦線をひくという関数です。
 
 
'''第一引数:'''ベース用のタブ譜向けの短い小節線をひきたい小節のオブジェクトをVexFlowの描画が終わったあとのグローバルな領域でも参照できるようにしたStave型のオブジェクトを引数に設定します。
 
 
 
 次の記事からタブ譜の中身を描くことに挑戦していかないといけないので、まだまだ創造力をはたからせないとタブ譜は完成しなさそうです。

VexFlow 使い方に戻る。

概要

 まともにVexFlowを使う気がないので、VexFlowを実直に学びたいという人向けの記事ではなくなる予定です。VexFlow応用しかやりません。覚えてもしょうがないことはやらないのがここの管理人の方針なのです。まずはタブ譜を表示するだけのことをやってみましょう。応用技をつかえば、ベースのタブ譜も描けるようになる優れた技術です。自称ですけど。


 ちな、2024年4月上旬、まだ書きかけの記事です。

 タブ譜を描いただけですが、ここではVexFlowのタブ譜の技術は使わず、通常の五線譜を二つ重ねているだけです。線が重なると少し汚くなるので、必要最小限になるよう。重ねる五線譜の一つは、10ピクセル上にずらした上で、一番上の線だけを描いています。小節線の長さは調節できないので、一部重なっています。これで6線50ピクセルの幅のタブ譜になります。TAB記号は自作のフォントを前の記事でもやった方法で追加しています。


 ベースのタブ譜は逆に4線譜にしないといけないので、ひとつ削っています。ただし、このままだと小節線が飛び出してしまうので、VexFlowの機能の小節線は描かないようにしました。そして、あらたに作った関数で、30ピクセルの小節線を描くようにしています。なので、この先、二重線にしたり、リピート記号を描いたりする必要が出てきたら、また関数はちょこっと変えていかないといけないのだと思います。繰り返し記号など全部の小節線の種類を網羅しないといけないですね。ベースタブ譜は公式でも対応できないので、これくらいの苦労はしかたないですね。


  • insertBaseEndBarPathToSVG(Stave)


 引数のStaveオブジェクトが示す小節に対して30ピクセルの縦線をひくという関数です。


第一引数:ベース用のタブ譜向けの短い小節線をひきたい小節のオブジェクトをVexFlowの描画が終わったあとのグローバルな領域でも参照できるようにしたStave型のオブジェクトを引数に設定します。


 次の記事からタブ譜の中身を描くことに挑戦していかないといけないので、まだまだ創造力をはたからせないとタブ譜は完成しなさそうです。
