Android–Paint画笔设置颜色过滤器

光照效果

/** LightingColorFilter(0xffffff,0x003000);* 第一个参数是去除照片中的某个颜色* 第二个参数是增加颜色更亮* 下面代码是绿色更亮* */LightingColorFilter lighting = new LightingColorFilter(0xffffff,0x003000);mPaint.setColorFilter(lighting);canvas.drawBitmap(bitmap,0,0,mPaint);

//红色去除掉LightingColorFilter lighting = new LightingColorFilter(0x00ffff,0x000000);mPaint.setColorFilter(lighting);canvas.drawBitmap(mBitmap, 0,0, mPaint);

//原始图片效果LightingColorFilter lighting = new LightingColorFilter(0xffffff,0x000000);mPaint.setColorFilter(lighting);canvas.drawBitmap(mBitmap, 0,0, mPaint);

颜色调节

/*
*颜色色值与照片叠加滤镜
*new PorterDuffColorFilter(Color.RED, PorterDuff.Mode.ADD);
*第一个参数是叠加的颜色
*第二个参数是叠加的模式，这点跟ps中图片叠加模式相似
*/PorterDuffColorFilter proterDuffColorFilter = new PorterDuffColorFilter(Color.RED, PorterDuff.Mode.ADD);mPaint.setColorFilter(proterDuffColorFilter);canvas.drawBitmap(bitmap,100,0,mPaint);

上面代码效果如下

Android–Paint画笔设置颜色矩阵过滤器

float[] colorMatrix = {1,0,0,0,100, //red0,1,0,0,0, //green0,0,1,0,100, //blue0,0,0,1,0, //alpha};ColorMatrixColorFilter matrixColorFilter = new ColorMatrixColorFilter(colorMatrix);mPaint.setColorFilter(matrixColorFilter);canvas.drawBitmap(bitmap,100,0,mPaint);

颜色矩阵过滤器也可以如下写

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);ColorMatrixColorFilter mColorMatrixColorFilter = new ColorMatrixColorFilter(cm);mPaint.setColorFilter(mColorMatrixColorFilter);canvas.drawBitmap(bitmap, 100, 0, mPaint);
