|
function CreateIntersectionArray: ArrayOfTIntersectionInfo; override; |
|
This item has no description. Showing description inherited from TFillShapeInfo.CreateIntersectionArray. create an array that will contain computed intersections. you may augment, in this case, use CreateIntersectionInfo for new items | |

|
function GetBounds: TRect; override; |
|
This item has no description. Showing description inherited from TFillShapeInfo.GetBounds. returns integer bounds | |

|
function NbMaxIntersection: integer; override; |
|
This item has no description. Showing description inherited from TFillShapeInfo.NbMaxIntersection. returns maximum of intersection per line | |
