PDF (Portable Document Format) is a file format developed by Adobe for presenting documents independently of software, hardware, or operating systems.
The pdf component allows finding text in PDF documents, listing page numbers, and extracting specific pages from a document.

| Input | Comments | Default |
|---|---|---|
| PDF Data | The PDF file data to process. This can be a file reference from a previous step. | |
| Line Tolerance | Y-coordinate tolerance in PDF points for grouping text items into lines. Items within this vertical distance are considered same-line. Default is 2 points. Increase for PDFs with inconsistent text positioning. | 2 |
| Page Start | The starting page number for extraction. If not provided, extraction starts from the first page. | |
| Page End | The ending page number for extraction. If not provided, extraction continues to the last page. |
Find Pattern {#findpattern}¶
Searches the PDF document and returns page numbers containing text that matches the search criteria.

| Search Pattern | The text pattern to search for in the PDF document. | |
| Case Sensitive | When true, the search is case-sensitive. | false |
| Use Regex | When true, treats the search pattern as a regular expression. | false |
| Contains | When true, returns pages containing the pattern; when false, returns pages without the pattern. | true |
Find Text Position {#findtextposition}¶
