| 15 | /** |
| 16 | * High-level PDF document builder — **zero PDF object-model knowledge |
| 17 | * required**. |
| 18 | * |
| 19 | * `Pdf` is a stateful, cursor-driven builder on top of {@see PdfWriter}. |
| 20 | * It maintains a current page, a text cursor, and a default font; each |
| 21 | * call flows content downward from the top margin, automatically |
| 22 | * breaking to a new page when the content column fills up. |
| 23 | * |
| 24 | * ### Example |
| 25 | * |
| 26 | * ```php |
| 27 | * $pdf = new Pdf(); // Letter, 72pt margins, Helvetica 11 |
| 28 | * $pdf->addHeading('Welcome', 1); |
| 29 | * $pdf->addText('This is body text. It wraps automatically to the content'); |
| 30 | * $pdf->addText('column width, and overflowing content starts a new page.'); |
| 31 | * $pdf->addSpacer(12); |
| 32 | * $pdf->addImage('/path/to/photo.jpg', width: 300); |
| 33 | * $pdf->save('/out.pdf'); |
| 34 | * ``` |
| 35 | * |
| 36 | * ### Output modes |
| 37 | * |
| 38 | * Three mutually-exclusive ways to emit the finished document: |
| 39 | * |
| 40 | * - `save(string $path)` — write to a file |
| 41 | * - `toBytes(): string` — get the bytes as a string |
| 42 | * - `writeTo($resource): int` — write to an open stream resource |
| 43 | * |
| 44 | * ### Scope |
| 45 | * |
| 46 | * Phase 1 handles the 80% case: word-wrapped body text, H1–H6 headings, |
| 47 | * images with auto-scaling, spacers, horizontal rules, explicit and |
| 48 | * automatic page breaks, and Left/Center/Right alignment. Fonts are |
| 49 | * limited to the 14 standard PDF fonts (Helvetica / Times / Courier |
| 50 | * families plus Symbol and ZapfDingbats). For custom TrueType fonts, |
| 51 | * embedded images with precise transforms, tables, or absolute-positioned |
| 52 | * graphics, drop to the underlying {@see PdfWriter} via {@see writer()}. |
