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 integer precision.
Member functions description¶
-
NatronEngine.RectI.
bottom
()¶ Return type: int
Returns the bottom edge, that is the
-
NatronEngine.RectI.
clear
()¶
Same as set
(0,0,0,0)
-
NatronEngine.RectI.
contains
(otherRect)¶ Parameters: otherRect – RectI
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.RectI.
height
()¶ Return type: int
Returns the height of the rectangle, that is: y2 - y1
-
NatronEngine.RectI.
intersect
(otherRect)¶ Parameters: otherRect – RectI
Return type: RectI
Returns the intersection between this rectangle and otherRect. If the intersection is empty,
the return value will have the isNull()
function return True.
-
NatronEngine.RectI.
intersects
(otherRect)¶ Parameters: otherRect – RectI
Return type: bool
Returns True if rectangle and otherRect intersect.
-
NatronEngine.RectI.
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.RectI.
isNull
()¶ Return type: bool
Returns true if x2 <= x1 or y2 <= y1
-
NatronEngine.RectI.
left
()¶ Return type: int
Returns x1, that is the position of the left edge of the rectangle.
-
NatronEngine.RectI.
merge
(otherRect)¶ Parameters: otherRect – RectI
Unions this rectangle with otherRect. In other words, this rectangle becomes the bounding box of this rectangle and otherRect.
-
NatronEngine.RectI.
left
() Return type: int
Returns x1, that is the position of the left edge of the rectangle.
-
NatronEngine.RectI.
right
()¶ Return type: int
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.RectI.
set
(x1, y1, x2, y2)¶ Parameters: - x1 –
int
- y1 –
int
- x2 –
int
- y2 –
int
- x1 –
Set the x1, y1, x2, y2 coordinates of this rectangle.
-
NatronEngine.RectI.
set_bottom
(y1)¶ Parameters: y1 – int
Set y1
-
NatronEngine.RectI.
set_left
(x1)¶ Parameters: y1 – int
Set x1
-
NatronEngine.RectI.
set_right
(x2)¶ Parameters: x2 – int
Set x2
-
NatronEngine.RectI.
set_top
(y2)¶ Parameters: y2 – int
Set y2
-
NatronEngine.RectI.
top
()¶ Return type: int
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.RectI.
translate
(dx, dy)¶ Parameters: - dx –
int
- dy –
int
- dx –
Moves all edges of the rectangle by dx, dy, that is:
x1 += dx;
y1 += dy;
x2 += dx;
y2 += dy;
-
NatronEngine.RectI.
width
()¶ Return type: int
Returns the width of the rectangle, that is x2 - x1.
