*
|
|
* Data returned by GdipGetRegionData (for rectangle based regions)
|
|
* looks something like this:
|
|
*
|
|
* struct region_data_header
|
|
* {
|
|
* DWORD size; size in bytes of the data - 8.
|
|
* DWORD magic1; probably a checksum.
|
|
* DWORD magic2; always seems to be 0xdbc01001 - version?
|
|
* DWORD num_ops; number of combining ops * 2
|
|
* };
|
|
*
|
|
* Then follows a sequence of combining ops and RECTFs.
|
|
*
|
|
* Combining ops are just stored as their CombineMode value.
|
|
*
|
|
* Each RECTF is preceded by the DWORD 0x10000000. An empty rect is
|
|
* stored as 0x10000002 (with no following RECTF) and an infinite rect
|
|
* is stored as 0x10000003 (again with no following RECTF).
|
|
*
|
|
* The combining ops are stored in the reverse order to the RECTFs and in the
|
|
* reverse order to which the region was constructed.
|
|
*
|
|
* When two or more complex regions (ie those with more than one rect)
|
|
* are combined, the combining op for the two regions comes first,
|
|
* then the combining ops for the rects in region 1, followed by the
|
|
* rects for region 1, then follows the combining ops for region 2 and
|
|
* finally region 2's rects. Presumably you're supposed to use the
|
|
* 0x10000000 rect header to find the end of the op list (the count of
|
|
* the rects in each region is not stored).
|
|
*
|
|
* When a simple region (1 rect) is combined, it's treated as if a single rect
|
|
* is being combined.
