===

Draw to an existing `ImageView`:

    // Prepare data

    Resources resources = activity.getResources();

    int width = 200;

    int height = 200;

    String chordName = "Am";

    int position = 0; // fret position index (0 to 8)

    int transpose = 0; // transpose distance (-12 to 12)

    

    // Draw chord

    BitmapDrawable chord = DrawHelper.getBitmapDrawable(

        resources, width, height, chordName, position, transpose);

        

    // Display chord to your image view

    yourImageView.setImageDrawable(chord);

Use `ChordTextureView`:

---

In your layout:

    

In your code:

    ChordTextureView chord = (ChordTextureView) findViewById(R.id.chord_texture_view);

    chord.drawChord("Am", 0);

Chord Helper

===

    ChordHelper.transpose(String chordName, int distance)

    ChordHelper.getChord(String chordName, int position)

    ChordHelper.simplifyName(String chordName)
