Define Documentation

#define GEOMLIBEXPORT   MI_DLLIMPORT
 

Definition at line 110 of file region.h.

#define REGIONCOMP_Inside   2
 

Element is inside the region.

Definition at line 160 of file region.h.

#define REGIONCOMP_Intersect   3
 

Element intersects the region.

Definition at line 161 of file region.h.

#define REGIONCOMP_Outside   1
 

Element is outside the region.

Definition at line 159 of file region.h.

#define REGIONCOMP_Overlap   4
 

Element overlaps the region, both inside and outside.

Definition at line 162 of file region.h.

#define REGIONFLAG_TestAsLines   0x00000001
 

Test element if possible as line data.

Definition at line 164 of file region.h.

#define REGIONTEST_ClipInside   5
 

Clip inside, not actual test.

Definition at line 156 of file region.h.

#define REGIONTEST_ClipOutside   6
 

Clip outside, not actual test.

Definition at line 157 of file region.h.

#define REGIONTEST_CompInside   1
 

Only elements completely inside region.

The DSUBREGION structure follows the same storage format as the CAD Polygon structure. The IsleNumPoints array is an array containing the number of points per island. The Points array contains both the points for the exterior polygon region and the islands. The layout of the points is as follows: first the exterior polygon is stored then the points for each island in the order stored in the IsleNumPoints array. If no islands exist, then the IsleNumPoints array is not allocated. Anything inside an island is considered to be "outside" the region. DREGION and DSUBREGION are defined in stddefns.h

Definition at line 152 of file region.h.

#define REGIONTEST_CompOutside   3
 

Only elements completely outside region.

Definition at line 154 of file region.h.

#define REGIONTEST_PartInside   2
 

All elements that partially or completely fall inside region.

Definition at line 153 of file region.h.

#define REGIONTEST_PartOutside   4
 

All elements that partially or completely fall outside region.

Definition at line 155 of file region.h.
