Only region points inside the image are painted.
Region points outside the image are ignored. In case of an empty region, the image is not modified.
Reimplemented from IDrawable.
| int area | ( | self | ) |
Calculate the area of the region.
The area is the number of pixels in the region.
| Point center_of_gravity | ( | self | ) |
Calculate the center of gravity of the region.
| MathErrorException | If the center of gravity could not be computed. |
| RegionArray connected_components | ( | self | ) |
Calculate the connected components of the region.
The 8-neighborhood is used to determine the components.
| Region create_from_points | ( | cls, | |
| Union[PointArray, npt.NDArray[np.int_]] | points ) |
Creates a region from points.
| points | NumPy Array of Point objects representing the region's points OR NumPy Array of Points [x,y] |
| OutOfRangeException | If a point at a given index has an invalid length. |
| NotSupportedException | If the parameter `points` is not a NumPy array of Point objects or a two-dimensional NumPy array. |
Creates a Region from a Rectangle.
| rect | Rectangle to create the region from |
| NotSupportedException | If the contents of rectangle are not integers. |
Computes the dilation of the input region with the given structuring element.
The reference point of the structuring element is at (0, 0).
| structuring_element |
Computes the erosion of the input region with the given structuring element.
The reference point of the structuring element is at (0, 0).
| structuring_element |
Computes the intersection of two regions.
| PointArray points | ( | self | ) |
Get the points of the region.
