Method for polygon

Functions

bbox_intersection	Compute bbox to check if there are a bbox intersection.
box_index	Return k_box index for each value
box_indexes	Return i_box,j_box index for each value
close_center	Compute an overlap with circle parameter and return a percentage
convex	Check if polygon is convex
convexs	Check if polygons are convex
create_meshed_particles
create_vertice	Return polygon vertice.
create_vertice_from_2darray	Choose a polygon in x,y list and return vertice.
fit_circle	From a polygon, function will fit a circle.
fit_circle_	From a polygon, function will fit a circle.
fit_ellipse	From a polygon, function will fit an ellipse.
get_convex_hull	Get convex polygon which enclosed current polygon
get_pixel_in_regular	Get a pixel list of a regular grid contain in a contour.
get_wrap_vertice	Return a vertice for each polygon and check that use same reference coordinates.
group_obs	Get index k_box for each box, and indexes to sort
insidepoly	True for each postion inside a contour
is_left	Test if point is left of an infinit line.
merge	Merge all polygon of the list
poly_area	Must be called with local coordinates (in m, to get an area in m²).
poly_area_vertice	Compute area from vertice.
poly_contain_poly	Check if poly_in is include in poly_out.
poly_indexs	Index of contour for each postion inside a contour, -1 in case of no contour
polygon_overlap	Return percent of overlap for each item.
reduce_size	Reduce array size if last position is repeated, in order to save compute time
shape_error	With a polygon(x,y) in local coordinates.
tri_area2	Double area of triangle
vertice_overlap	Return percent of overlap for each item.
visvalingam	Polygon simplification with visvalingam algorithm
winding_number_grid_in_poly	Return index for each grid coordinates within contour.
winding_number_poly	Check if x,y is in poly.
