Classes

struct  csVertexStatus
 The clipper can output additional information about each vertex in output polygon. More...
struct  iClipper2D
 This interfaces represents a 2D clipper for polygons. More...

Defines

#define MAX_OUTPUT_VERTICES   64
 Maximal number of vertices in output (clipped) polygons.

Enumerations

Clipper return codes

The clipper routines return one of CS_CLIP_OUTSIDE, CS_CLIP_INSIDE, CS_CLIP_CLIPPED so that we can distinguish between the cases when input polygon is completely outside the clipping polygon (thus it is not visible), completely inside the clipping polygon (thus it has not changed) and partially outside, partially inside (thus it was clipped).

enum  { CS_CLIP_OUTSIDE = 0, CS_CLIP_CLIPPED = 1, CS_CLIP_INSIDE = 2 }
Additional vertex informations

enum  { CS_VERTEX_ORIGINAL = 0, CS_VERTEX_ONEDGE = 1, CS_VERTEX_INSIDE = 2 }
 

Clipped vertex type.
