Python Imaging Library (Fork)
cd332fc38a
The (previously refactored) polygon_generic function didn't draw
consistent polygons (equilateral polygons were not equilateral nor
symmetrical).
The most notable changes are:
* The horizontal edges are searched for when finding the polygon
boundaries, drawn and discarded from the edge list used to detect
intersections.
* The intersections are now checked and calculated from the current value
of the scan line (ymin) instead of in the middle (ymin + 0.5).
* Because the change in the scan line behavior, we should duplicate
the intersections in the maximum Y value of an edge or there will be
draw errors with concave and complex polygons.
* The rounds of the X coordinates in the hline function calls are
switched to draw the inner pixels.
* Removed the ugly micro-optimization of qsort at the end.
This implementation of the scan line algorithm may not be technically
correct, it's not optimized and it have problems with some edge cases,
like a wide line from (x0, y) to (x1, y + 1), therefore it should be
reviewed in the future.
