Aligns rectangle to a regular tile grid, of which tile is a representative
tile, and stores the result in destination.
alignment can be one of:
GEGL_RECTANGLE_ALIGNMENT_SUBSET: Calculate the biggest aligned rectangle
contained in rectangle.
GEGL_RECTANGLE_ALIGNMENT_SUPERSET: Calculate the smallest aligned
rectangle containing rectangle.
GEGL_RECTANGLE_ALIGNMENT_NEAREST: Calculate the nearest aligned rectangle
to rectangle.
destination may point to the same object as rectangle or tile.
Returns TRUE if the result is not empty.
a #GeglRectangle
a #GeglRectangle
a #GeglRectangleAlignment value
Aligns rectangle to the tile grid of buffer, and stores the result in
destination.
alignment has the same meaning as for gegl_rectangle_align().
destination may point to the same object as rectangle.
Returns TRUE if the result is not empty.
a #GeglRectangle
a #GeglBuffer
a #GeglRectangleAlignment value
For debugging purposes, not stable API.
Check if a rectangle is equal to a set of parameters.
Returns TRUE if rectangle and x,``y width x height are equal.
X coordinate
Y coordinate
width of rectangle
height of rectangle
Calculates the intersection of two rectangles. If the rectangles do not intersect, dest's width and height are set to 0 and its x and y values are undefined.
dest may point to the same object as src1 or src2.
Returns TRUE if the rectangles intersect.
Check if a rectangle has zero area.
Returns TRUE if the width or height of rectangle is 0.
Returns TRUE if the GeglRectangle represents an infininte plane, FALSE otherwise.
Sets the x, y, width and height on rectangle.

height in pixels.
Subtracts subtrahend from minuend, and stores the resulting rectangles in
destination. Between 0 and 4 disjoint rectangles may be produced.
destination may contain minuend or subtrahend.
Returns the number of resulting rectangles.
Computes the bounding box of the area formed by subtracting subtrahend
from minuend, and stores the result in destination.
destination may point to the same object as minuend or subtrahend.
Returns TRUE if the result is not empty.
Computes the symmetric difference of the rectangles source1 and source2,
and stores the resulting rectangles in destination. Between 0 and 4
disjoint rectangles may be produced.
destination may contain rectangle1 or rectangle2.
Returns the number of resulting rectangles.
Creates a new rectangle set with the values from
x,y,widthandheight.
