                   JComponent component)

Method Detail

getBoundingBox

public BoundingBox getBoundingBox(double x,
                         double y,
                         double scale)

Get the bounding box for the dimensions of the viewport at the specified scale, centred at the x, y model coordinates.

Parameters:

x - The model x coordinate.

y - The model y coordinate.

scale - The scale.

Returns:

The bounding box.

getBoundingBox

public BoundingBox getBoundingBox(double x1,
                         double y1,
                         double x2,
                         double y2)

Get the bounding box in model units for the pair of coordinates in view units. The bounding box will be clipped to the model's bounding box.

Parameters:

x1 - The first x value.

y1 - The first y value.

x2 - The second x value.

y2 - The second y value.

Returns:

The bounding box.

getBoundingBox

public BoundingBox getBoundingBox(int x,
                         int y,
                         double scale)

Get the bounding box for the dimensions of the viewport at the specified scale, centred at the x, y view coordinates.

Parameters:

x - The view x coordinate.

y - The view y coordinate.

scale - The scale.

Returns:

The bounding box.
