Detailed Description
A rectangle where x1 < x2 and y1 < y2 such as width() == (x2 - x1) && height() == (y2 - y1) (x1,y1) is are the coordinates of the bottom left corner of the rectangle. The last element valid in the y dimension is y2 - 1 and the last valid in the x dimension is x2 - 1. x1,x2,y1 and y2 are with floating point precision.
Member functions description
- NatronEngine.RectD.area()
- Return type
double
Returns the area covered by the rectangle, that is: (y2 - y1) * (x2 - x1)
- NatronEngine.RectD.bottom()
- Return type
double
Returns the bottom edge, that is the
- NatronEngine.RectD.clear()
Same as set
(0,0,0,0)
- NatronEngine.RectD.contains(otherRect)
- Parameters
otherRect –
RectD
- Return type
bool
Returns True if otherRect is contained in or equals this rectangle, that is if:
otherRect.x1 >= x1 and
otherRect.y1 >= y1 and
otherRect.x2 <= x2 and
otherRect.y2 <= y2
- NatronEngine.RectD.height()
- Return type
double
Returns the height of the rectangle, that is: y2 - y1
- NatronEngine.RectD.intersect(otherRect)
- Parameters
otherRect –
RectD
- Return type
RectD
Returns the intersection between this rectangle and otherRect. If the intersection is empty,
the return value will have the isNull()
function return True.
- NatronEngine.RectD.intersects(otherRect)
- Parameters
otherRect –
RectD
- Return type
bool
Returns True if rectangle and otherRect intersect.
- NatronEngine.RectD.isInfinite()
- Return type
bool
Returns True if this rectangle is considered to cover an infinite area. Some generator effects use this to indicate that they can potentially generate an image of infinite size.
- NatronEngine.RectD.isNull()
- Return type
bool
Returns true if x2 <= x1 or y2 <= y1
- NatronEngine.RectD.left()
- Return type
double
Returns x1, that is the position of the left edge of the rectangle.
- NatronEngine.RectD.merge(otherRect)
- Parameters
otherRect –
RectD
Unions this rectangle with otherRect. In other words, this rectangle becomes the bounding box of this rectangle and otherRect.
- NatronEngine.RectD.left()
- Return type
double
Returns x1, that is the position of the left edge of the rectangle.
- NatronEngine.RectD.right()
- Return type
double
Returns x2, that is the position of the right edge of the rectangle. x2 is considered to be the first element outside the rectangle.
- NatronEngine.RectD.set(x1, y1, x2, y2)
- Parameters
x1 –
double
y1 –
double
x2 –
double
y2 –
double
Set the x1, y1, x2, y2 coordinates of this rectangle.
- NatronEngine.RectD.set_bottom(y1)
- Parameters
y1 –
double
Set y1
- NatronEngine.RectD.set_left(x1)
- Parameters
y1 –
double
Set x1
- NatronEngine.RectD.set_right(x2)
- Parameters
x2 –
double
Set x2
- NatronEngine.RectD.set_top(y2)
- Parameters
y2 –
double
Set y2
- NatronEngine.RectD.top()
- Return type
double
Returns y2, that is the position of the top edge of the rectangle. y2 is considered to be the first element outside the rectangle.
- NatronEngine.RectD.translate(dx, dy)
- Parameters
dx –
double
dy –
double
Moves all edges of the rectangle by dx, dy, that is:
x1 += dx;
y1 += dy;
x2 += dx;
y2 += dy;
- NatronEngine.RectD.width()
- Return type
double
Returns the width of the rectangle, that is x2 - x1.
