使绘制的文本清晰的步骤

Question

我已经写了在图像上绘制文本和保存图像的代码，但我正在绘制的文本在image.What上看起来模糊，需要修改以使其清晰，或者是否有任何其他方法在安卓图像上绘制文本

Canvas canvas = new Canvas(photo);
                Typeface tf = Typeface.create(topaste, Typeface.BOLD);
                Paint paint = new Paint();
                paint.setStyle(Style.FILL);
                paint.setTypeface(tf);
                paint.setColor(Color.WHITE);

                paint.setStrokeWidth(12); 
                canvas.drawBitmap(photo, 0, 0, paint);
                canvas.drawText(topaste, 15, 120, paint);
                image.setImageBitmap(photo);

Answer 1

你试着这样做

        public void onClick(View v) {
            mBitmap.eraseColor(Color.TRANSPARENT);
            mPath.reset();
            mView.invalidate();
        }
