| 14 | * PDF Border Style dictionary (/Type /Border). |
| 15 | * |
| 16 | * Describes the border drawn around annotations that support it |
| 17 | * (Link, FreeText, Line, Square, Circle, Polygon, PolyLine, etc.). |
| 18 | * Assigned to the /BS entry of those annotation dictionaries. |
| 19 | * |
| 20 | * Style (/S) values: |
| 21 | * S - Solid |
| 22 | * D - Dashed |
| 23 | * B - Beveled |
| 24 | * I - Inset |
| 25 | * U - Underline |
| 26 | * |
| 27 | * Example: |
| 28 | * $bs = new BorderStyle(); |
| 29 | * $bs->w = new PdfNumber(2.0); |
| 30 | * $bs->s = new PdfName('D'); |
| 31 | * $bs->d = new PdfArray([new PdfNumber(3), new PdfNumber(2)]); |
