| # fpdfapi/ |
| |
| This subdirectory contains the central implementation of the PDF specification, |
| ranging from low-level parsing to high-level page representation and rendering. |
| |
| ## Subdirectories |
| |
| * **[cmaps/](cmaps/)**: Logic and static data for character mapping, providing |
| the necessary infrastructure to support multi-byte character sets (CJK) and |
| custom encoding mappings. |
| * **[edit/](edit/)**: Tools for modification and creation. Contains the logic |
| for document generation, page organization, and font subsetting. |
| * **[font/](font/)**: PDF-specific font logic, including Type1, TrueType, and |
| CIDFont implementations, as well as glyph mapping and font resource |
| management. |
| * **[page/](page/)**: Provides a logical representation of PDF objects as |
| high-level page content. This includes managing resources like fonts, |
| colorspaces, and interpreting content streams into interactive objects. |
| * **[parser/](parser/)**: The foundations of PDF reading. Handles low-level |
| syntax (objects, arrays, dictionaries), cross-reference tables, and the |
| incremental update system. |
| * **[render/](render/)**: The bridge between the PDF object graph and the |
| graphics engine. It coordinates the translation of page objects into drawing |
| calls for the rendering backends. |
