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
 x1 –
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
 dx –
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.
