ColorFilter：颜色过滤器，使用方法可以给图片加上滤镜效果
只对Google已经封装好的方法使用,也可以使用矩阵下来下来在研究
float[] colorMatrix = {
2,0,0,0,0, //red
0,1,0,0,0, //green
0,0,1,0,0, //blue
0,0,0,1,0 //alpha
};
ColorMatrix cm = new ColorMatrix();
// //亮度调节
cm.setScale(1,2,1,1);
// //饱和度调节0-无色彩， 1- 默认效果， >1饱和度加强
cm.setSaturation(2);
//色调调节
cm.setRotate(0, 45);
mColorMatrixColorFilter = new ColorMatrixColorFilter(cm);
mPaint.setColorFilter(mColorMatrixColorFilter);
canvas.drawBitmap(mBitmap, 100, 0, mPaint);
