| getClipped | | public static Point2D[] getClipped(double x1, double y1, double x2, double y2, double xmin, double xmax, double ymin, double ymax)(Code) | | Calculate the clipping points of a line with a rectangle.
Parameters:
x1 - starting x of line
Parameters:
y1 - starting y of line
Parameters:
x2 - ending x of line
Parameters:
y2 - ending y of line
Parameters:
xmin - lower left x of rectangle
Parameters:
xmax - upper right x of rectangle
Parameters:
ymin - lower left y of rectangle
Parameters:
ymax - upper right y of rectangle null (does not clip) or array of two points |
| performCliping | | public static Shape performCliping(Shape s, Rectangle2D bounds)(Code) | | Clips the given shape to the given bounds. If the shape is a Line2D, manual
clipping is performed, as the built in Area does not handle lines.
Parameters:
s - the shape to be clipped
Parameters:
bounds - the bounds to which the shape should be clipped the clipped shape. |
| resizeRect | | public static Shape resizeRect(RectangularShape rectangularShape, double width, double height)(Code) | | Resizes a rectangle. This works for real rectangles and produces funny results
for RoundRects etc ..
Parameters:
rectangularShape - the rectangle
Parameters:
width - the new width of the rectangle
Parameters:
height - the new height of the rectangle. the resized rectangle. |
| resizeShape | | public static Shape resizeShape(Shape s, float width, float height)(Code) | | Resizes a shape, so that the shape has the given width and height, but the origin of
the shape does not change.
Unlike the AffineTransform, this method tries to preserve the Shape's Type.
Parameters:
s - the shape
Parameters:
width - the new width
Parameters:
height - the new height the resized shape. |
| transformShape | | public static Shape transformShape(Shape s, boolean scale, boolean keepAR, double width, double height)(Code) | | Translates the given shape. The shape is translated to the origin supplied in
point. If scaling is requested, the shape will also be scaled using an
AffineTransform.
Parameters:
s - the shape that should be transformed
Parameters:
scale - true, if the shape should be scaled, false otherwise
Parameters:
keepAR - true, if the scaled shape should keep the aspect ratio
Parameters:
width - the target width.
Parameters:
height - the target height. the transformed shape |
| transformShape | | public static Shape transformShape(Shape s, boolean scale, boolean keepAR, Dimension2D dim)(Code) | | Translates the given shape. The shape is translated to the origin supplied in
point. If scaling is requested, the shape will also be scaled using an
AffineTransform.
Parameters:
s - the shape that should be transformed
Parameters:
scale - true, if the shape should be scaled, false otherwise
Parameters:
keepAR - true, if the scaled shape should keep the aspect ratio
Parameters:
dim - the target dimension. the transformed shape |
| translateShape | | public static Shape translateShape(Shape s, double x, double y)(Code) | | Translates a given shape. Special care is taken to preserve the shape's original
class, if the shape is a rectangle or a line.
Parameters:
s - the shape
Parameters:
x - the x coordinate where the shape is translated to
Parameters:
y - the y coordinate where the shape is translated to the translated shape |
