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