Document

Set this colormatrix to the concatenation of the two specified colormatrices, such that the resulting colormatrix has the same effect as applying matB and then applying matA.

Usage

From source file:Main.java

public static Bitmap toSepia(Bitmap bmpOriginal) {
    int width, height;
    height = bmpOriginal.getHeight();/*from   ww w.j av a  2  s. c  om*/
    width = bmpOriginal.getWidth();

    Bitmap bmpGrayscale = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
    Canvas c = new Canvas(bmpGrayscale);
    Paint paint = new Paint();

    ColorMatrix grMatrix = new ColorMatrix();
    grMatrix.setSaturation(0);

    ColorMatrix scMatrix = new ColorMatrix();
    scMatrix.setScale(1f, .85f, .72f, 1.0f);
    grMatrix.setConcat(scMatrix, grMatrix);

    ColorMatrixColorFilter f = new ColorMatrixColorFilter(grMatrix);
    paint.setColorFilter(f);
    c.drawBitmap(bmpOriginal, 0, 0, paint);
    return bmpGrayscale;
