    In This Topic

    This function gets a pointer to the optional attribute specified by the parameter nAttrib.

    Declaration:

     
    Copy Code
    AT_ERRCOUNT ACCUAPI IG_vect_layer_get_attrib(
            HIG_VECT_LAYER hLayer, 
            enumIGVectAttrib nAttrib, 
            VOID** lplpAttribPtr
    );
    

    Arguments:

    Name Type Description
    hLayer HIG_VECT_LAYER Handle to the Layer.
    nAttrib enumIGVectAttrib Constant specifying which attribute should be returned.
    lpAttribPtr VOID** Buffer that receives a pointer or handle to the attribute. Buffer type depends on the nAttrib parameter.

    The attribute type is associated with the buffer type as follows:

    Attribute Type Buffer Type
    IG_VECT_ENT_ATTR_DRAWCOLOR IGVectColorEx*
    IG_VECT_ENT_ATTR_FILLCOLOR IGVectColorEx*
    IG_VECT_ENT_ATTR_LINETYPEINDEX long*
    IG_VECT_ENT_ATTR_THICKNESS float*
    IG_VECT_ENT_ATTR_FILLTYPEINDEX long*

    Return Value:

    Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.
