アルファベット文字の図式表現を取得する

Question

アンドロイドには、私の空間的な表現（例えば 'A'）が表示されます。点の配列やパスオブジェクトやベクトルのようなもの。私はcanvas.drawText（）を使用する代わりに、自分自身で画面に文字を描画します。これは可能ですか？

Answer 1

ここでポイントを返し、別の方法です：

private void textStuff() { 
    int textSize = 32; 
    char letter = 'A'; 
    getPointsForChar(textSize, letter); 
} 

@NonNull 
private ArrayList<Point> getPointsForChar(int textSize, char letter) { 
    Canvas canvas = new Canvas(); 
    Paint paint = new Paint(); 
    Bitmap bitmap = Bitmap.createBitmap((int) (float) textSize, (int) (float) textSize, Bitmap.Config.ALPHA_8); 
    canvas.drawPaint(paint); 
    canvas.setBitmap(bitmap); 
    paint.setColor(Color.BLACK); 
    paint.setTextSize(textSize); 
    canvas.drawText(String.valueOf(letter), 0, (float) textSize, paint); 
    Log.d("Font", "bitmap " + bitmap.toString()); 
    ArrayList<Point> points = new ArrayList<>(); 
    for (int x = 0; x < bitmap.getWidth(); x++) { 
     for (int y = 0; y < bitmap.getHeight(); y++) { 
      int pixel = bitmap.getPixel(x, y); 
      if (pixel != Color.TRANSPARENT) { 
       points.add(new Point(x, y)); 
      } 
     } 
    } 

    StringBuilder stringBuilder = new StringBuilder("The following points make up '" + letter + "':"); 
    for (Point point : points) { 
     stringBuilder.append("\n\t").append(point.toString()).append(", "); 
    } 

    Log.d("Font", stringBuilder.toString()); 
    return points; 
} 

上記の方法の出力は次のとおりです。

The following points make up 'A': 
    Point(1, 29), 
    Point(1, 30), 
    Point(1, 31), 
    Point(2, 27),

Answer 2

Pathは、次のコードを使用して取得できます。私はまだこのコードによって生成されたパスがネイティブパスであり、というではないので、より有用なパスを得る方法があるかどうかを調べようとしています。

Path path = new Path(); 
Paint paint = new Paint(); 
paint.getTextPath("A", 0, 1, 0f, 0f, path);
