}
privateBitmap createWatermark(Bitmap bitmap, String mark) {
intw = bitmap.getWidth();
inth = bitmap.getHeight();
Bitmap bmp = Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_8888);
Canvas canvas =newCanvas(bmp);
Paint p =newPaint();
// 水印颜色
p.setColor(Color.parseColor("#c5576370"));
// 水印字体大小
p.setTextSize(150);
//抗锯齿
p.setAntiAlias(true);
//绘制图像
canvas.drawBitmap(bitmap,0,0, p);
//绘制文字
canvas.drawText(mark,0, h /2, p);
canvas.save(Canvas.ALL_SAVE_FLAG);
canvas.restore();
returnbmp;
}
}
