Usage

From source file:Main.java

public static Matrix getScaleMatrix(float toWidth, int fromWidth, float toHeight, int fromHeight) {
    Matrix matrix = new Matrix();
    matrix.postScale(toWidth / fromWidth, toHeight / fromHeight);
    return matrix;
}

From source file:Main.java

public static Bitmap scaleBitmap(Bitmap bitmap, float widthRatio, float heightRatio) {
    Matrix matrix = new Matrix();
    matrix.postScale(widthRatio, heightRatio);
    return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
}

From source file:Main.java

public static Bitmap doScale(Bitmap b, float scale) {
    Matrix matrix = new Matrix();
    matrix.postScale(scale, scale);
    b = Bitmap.createBitmap(b, 0, 0, b.getWidth(), b.getHeight(), matrix, true);
    return b;/*w  ww . j  a va 2 s . com*/
}

From source file:Main.java

    return newBitmap;
}

From source file:Main.java
