How can we specify the text size, type, density when creating bitmap

I'm trying to create a bitmap with text on it. but I'm having troubles in specifying the options for that text, like the size, type, smoothness.

Here is my code:

Bitmap resultBitmap=Bitmap.createBitmap(384,384, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(resultBitmap);
canvas.drawColor(Color.WHITE);
Paint paint = new Paint();
paint.setColor(Color.BLACK); // Text Color  
paint.setStrokeWidth(24); // Text Size      
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_OVER)); // Text Overlapping Pattern

// some more settings...
canvas.drawBitmap(resultBitmap, 0, 0, paint);
canvas.drawText("00: Some text", 300, 10, paint);
Solution

  • The problem with density was the size of the bitmap itself, while it's small, the printed texts cannot be smooth! Text size:

    paint.setTextSize(fontSize);

    density is the same problem like smoothing, so just make it bigger.

    type:

    paint.setTypeface(Typeface.create(Typeface.DEFAULT_BOLD, Typeface.BOLD));

    color:

    paint.setColor(Color.BLACK);

    background color:

    canvas.drawColor(Color.WHITE);
