ImageData DrawOnImage(ImageData imageData, LineSegment[] lines, int color = unchecked((int)0xFFFF0000), int thickness = 1);
ImageData DrawOnImage(ImageData imageData, Contour[] contours, int color = unchecked((int)0xFFFF0000), int thickness = 1);
ImageData DrawOnImage(ImageData imageData, Corner[] corners, int color = unchecked((int)0xFFFF0000), int thickness = 1);
ImageData DrawOnImage(ImageData imageData, Edge[] edges, int color = unchecked((int)0xFFFF0000), int thickness = 1);
```
