public TiledImageBackground(ej.microui.display.Image image)
```
    Creates a tiled image background aligned on the top-left corner and repeated horizontally and vertically.
    
    Parameters:
    
    image - the background image.

```
public TiledImageBackground(ej.microui.display.Image image,
                            int horizontalAlignment,
                            int verticalAlignment,
                            boolean horizontalRepeat,
                            boolean verticalRepeat)
```
    Creates a tiled image background specifying its attributes.
    
    Parameters:
    
    image - the background image.
    
    horizontalAlignment - the horizontal alignment.
    
    verticalAlignment - the vertical alignment.
    
    horizontalRepeat - true if the image is repeated horizontally, false otherwise.
    
    verticalRepeat - true if the image is repeated vertically, false otherwise.
    
    Throws:
    
    IllegalArgumentException - if the horizontal or vertical alignment is not valid.

  - isTransparent
```
public boolean isTransparent(int width,
                             int height)
```
    Description copied from interface: Background
    
    Tells whether or not this background is transparent.
    A background is considered as transparent if it does not draw every pixel with maximal opacity when it is applied. If a widget has a transparent background, its parent has to be rendered before the widget.
    
    Specified by:
    
    isTransparent in interface Background
    
    Parameters:
    
    width - the width of the background.
    
    height - the height of the background.
    
    Returns:
    
    true if the background is transparent, false otherwise.
  - apply
```
public void apply(ej.microui.display.GraphicsContext g,
                  int width,
                  int height)
```
    Description copied from interface: Background
    
    Applies the background on a graphics context.
    
    Specified by:
    
    apply in interface Background
    
    Parameters:
    
    g - the graphics context.
    
    width - the width of the background.
    
    height - the height of the background.
  - equals
```
public boolean equals(@Nullable
                      Object obj)
```
    Description copied from class: Object
    Indicates whether some other object is "equal to" this one.
    The equals method implements an equivalence relation on non-null object references:
    - It is reflexive: for any non-null reference value x, x.equals(x) should return true.
    - It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
    - It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
    - It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
    - For any non-null reference value x, x.equals(null) should return false.
    The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).
    Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.
    Specified by:
    
    equals in interface Background
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the reference object with which to compare.
    
    Returns:
    
    true if this object is the same as the obj argument; false otherwise.

  - hashCode
```
public int hashCode()
```
    Description copied from class: Object
    Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.
    The general contract of hashCode is:
    - Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
    - If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
    - It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
    As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)
    Specified by:
    
    hashCode in interface Background
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a hash code value for this object.
