VECTOR_DISPLAY_OPTIONS

typedef struct _VECTOR_DISPLAY_OPTIONS 
{ 
   VECTOR_TEXTRENDER TextRender; 
   VECTOR_ANTIALIASING AntiAliasing; 
   L_INT nClipMode; 
   L_SIZE_T dwReserved; 
}VECTOR_DISPLAY_OPTIONS, *pVECTOR_DISPLAY_OPTIONS; 

The VECTOR_DISPLAY_OPTIONS structure has the display settings for the vector toolkit. Some or all of the members can be set to apply some effects or filters to the output.

Comments

pVECTOR_DISPLAY_OPTIONS is a pointer to a VECTOR_DISPLAY_OPTIONS structure. Where the function parameter type is pVECTOR_DISPLAY_OPTIONS, you can declare a VECTOR_DISPLAY_OPTIONS variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pVECTOR_DISPLAY_OPTIONS variable is necessary only if your program requires a pointer.

The VECTOR_DISPLAY_OPTIONS structure is used with the LVectorBase::GetDisplayOptions and LVectorBase::SetDisplayOptions functions.

A clipping polydraw sets a clipping region that is applied to any vector object added after the clipping polydraw is added. For example, if the user adds object #1, then adds a clipping polydraw, and then adds objects #2 and #3, the toolkit will draw object #1 without modification. It will then render the clipping polydraw, which will set a clipping region. the toolkit will then draw objects #2 and #3, which will be clipped according to the clipping polydraw and the clip mode specified in nClipMode.

If nClipMode is set to 0, no clipping will be performed.
