| 236 | * document. Consecutive calls will have no effect, except for creating a new |
| 237 | * page. The situation is different if you intent to convert the PostScript |

| 240 | * have different page sizes. |

| 242 | * Though PostScript does not know different page sizes, pslib places |
| 243 | * a bounding box for each page into the document. This size is evaluated |
| 244 | * by some PostScript viewers and will have precedence over the BoundingBox |
| 245 | * in the Header of the document. This can lead to unexpected results when |
| 246 | * you set a BoundingBox whose lower left corner is not (0, 0), because the |
| 247 | * bounding box of the page will always have a lower left corner (0, 0) |
| 248 | * and overwrites the global setting. |
