The HOTS attachment (Hotspot Information) defines the hotspot associated with the image as would be the case for a cursor or a pinned texture. This replaces image hotspot mark-up and can be edited directly in the Layer Properties window in the user interface for Chasys Draw IES. The metadata consists of a host-defined structure of a fixed length:
#define META_HOTS_VERSION 0x0001
struct meta_HOTS_Obj
{
unsigned short version; //HOTS version
unsigned short unused_1; //unused, set to 0
long x;
//hotspot, x
long y;
//hotspot, y
unsigned long unused_2; //unused, set to 0
};
The plug-in requests metadata of size sizeof(meta_HOTS_Obj). The plug-in then proceeds to fill the structure with the hotspot position and the version of the structure.
