41 /* Notes on the implementation
43 * The implementation is based on dynamically resizable arrays of points and
44 * flags. I dithered for a bit before deciding on this implementation, and
45 * I had even done a bit of work on a linked list version before switching
46 * to arrays. It's a bit of a tradeoff. When you use linked lists, the
47 * implementation of FlattenPath is easier, because you can rip the
48 * PT_BEZIERTO entries out of the middle of the list and link the
49 * corresponding PT_LINETO entries in. However, when you use arrays,
50 * PathToRegion becomes easier, since you can essentially just pass your array
51 * of points to CreatePolyPolygonRgn. Also, if I'd used linked lists, I would
52 * have had the extra effort of creating a chunk-based allocation scheme
53 * in order to use memory effectively. That's why I finally decided to use
54 * arrays. Note by the way that the array based implementation has the same
55 * linear time complexity that linked lists would have since the arrays grow
56 * exponentially.
58 * The points are stored in the path in device coordinates. This is
59 * consistent with the way Windows does things (for instance, see the Win32
60 * SDK documentation for GetPath).
62 * The word "stroke" appears in several places (e.g. in the flag
63 * GdiPath.newStroke). A stroke consists of a PT_MOVETO followed by one or
64 * more PT_LINETOs or PT_BEZIERTOs, up to, but not including, the next
65 * PT_MOVETO. Note that this is not the same as the definition of a figure;
66 * a figure can contain several strokes.
