一点片段，仅供参阅

var
lyr: Layer;
ft: FindFeature;
ds: Dataset;
……
ft := lyr.Find.Search(strID, EmptyParam);
if ft.type_ = miFeatureTypeRegion then
begin
ft.Style.RegionColor := clr; //clr: TColor;
ft.Update(strID, EmptyParam);
end;

Specifying Point Styles

Use a Symbol clause to specify point styles. There are three types of Symbol clauses: one for specifying MapInfo 3.0-style symbols; one for specifying TrueType font symbols; and one for specifying bitmap symbols.

Symbol Syntax Example
Symbol(shape, color, size): Symbol(35,0,12)；
Symbol(shape,color,size,font,fontstyle,rotation): Symbol(64,255,12,"MapInfo Weather" ,17,0)；
Symbol(bitmapname,color,size,customstyle): Symbol("sign.bmp", 255, 18, 0) 。
