/**********************************************************
|
|
*
|
|
* Data returned by GdipGetRegionData 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 region elements.
|
|
*
|
|
* A region element is either a RECTF or some path data.
|
|
*
|
|
* 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).
|
|
*
|
|
* Path data is preceded by the DWORD 0x10000001. Then follows a
|
|
* DWORD size and then size bytes of data.
|
|
*
|
|
* The combining ops are stored in the reverse order to the region
|
|
* elements and in the reverse order to which the region was
|
|
* constructed.
|
|
*
|
|
* When two or more complex regions (ie those with more than one
|
|
* element) are combined, the combining op for the two regions comes
|
|
* first, then the combining ops for the region elements in region 1,
|
|
* followed by the region elements for region 1, then follows the
|
|
* combining ops for region 2 and finally region 2's region elements.
|
|
* Presumably you're supposed to use the 0x1000000x header to find the
|
|
* end of the op list (the count of the elements in each region is not
|
|
* stored).
|
|
*
|
|
* When a simple region (1 element) is combined, it's treated as if a
|
|
* single rect/path is being combined.
