Method

voidaddTo(Insets i1, Insets i2)
add To 
i2.top += i1.top;
i2.left += i1.left;
i2.bottom += i1.bottom;
i2.right += i1.right;
voidalignComponentsBaseHorizontal(Component left, Component right)
align Components Base Horizontal 
Rectangle leftBounds = left.getBounds();
Rectangle rightBounds = right.getBounds();
leftBounds.y = rightBounds.y + rightBounds.height - leftBounds.height;
left.setBounds(leftBounds);
booleanalignsVertically(Rectangle r1, Rectangle r2)
aligns Vertically 
return r1.getMaxX() == r2.getMaxX() && r1.getMinX() == r2.getMinX();
voidclip(int x, int y, int w, int h)
clip 
cX = x;
cY = y;
cW = w;
cH = h;
clip.x = x;
clip.y = y;

Rectangle[]computeDifference(Rectangle rectA, Rectangle rectB)
Subtracts a rectangle from another and return the area as an array of rectangles. 
if (rectA == null || rectB == null)
    return new Rectangle[0];
Rectangle[] r = new Rectangle[4];
int x1 = rectA.x;
int y1 = rectA.y;
int w1 = rectA.width;
int h1 = rectA.height;
int x2 = rectB.x;
...
Rectangleexpand(final Rectangle rect, final int expansion)
Returns rectangle expanded in four directions for the specified value. 
return expand(rect, expansion, expansion, expansion, expansion);
Rectangleexpand(Rectangle rect, int amount)
expand 
return new Rectangle(rect.x - amount, rect.y - amount, rect.width + amount * 2, rect.height + amount * 2);
voidexpand(Rectangle rectangle, int expansion)
expand 
rectangle.x -= expansion;
rectangle.y -= expansion;
rectangle.width += expansion * 2;
rectangle.height += expansion * 2;
booleanfirstSmallerThanSecond(java.awt.Rectangle first, java.awt.Rectangle second)
first Smaller Than Second 
int areaFirst = (int) (first.getSize().getHeight() * first.getSize().getWidth());
int areaSecond = (int) (second.getSize().getHeight() * second.getSize().getWidth());
return areaFirst < areaSecond;
Rectangleflip(Dimension view, Rectangle rect, int direction)
flip 
boolean flipHorizontal = (direction & 1) == 1;
boolean flipVertical = (direction & 2) == 2;
int x = flipHorizontal ? view.width - (rect.x + rect.width) : rect.x;
int y = flipVertical ? view.height - (rect.y + rect.height) : rect.y;
System.out.println(rect + " - " + new Rectangle(x, y, rect.width, rect.height));
return new Rectangle(x, y, rect.width, rect.height);
