| 53 | +1. Upload your document file |
| 54 | +1. Perform the extracting attachment actions for PDf document using one of the function getDocumentAttachments or getDocumentAttachmentByIndex or getDownloadDocumentAttachmentByIndex as shown in the next example |
| 55 | +1. Also you can perform extracting actions for PDF document using one of the function getDownloadDocumentAttachment or getDocumentFileAttachmentAnnotations or getDownloadDocumentAttachment or getDownloadDocumentAttachment |
| 56 | +1. To perform extracting actions for PDF documsnt page you can perform function getPageFileAttachmentAnnotations |
| 57 | +1. Perform the appending attachment actions for PDf document using postAddDocumentAttachment or perform appending attachments to page using postPageFileAttachmentAnnotations fumction |
| 58 | +1. Perform replacement attachment actions for PDF document using postPageFileAttachmentAnnotations or putFileAttachmentAnnotation or putFileAttachmentAnnotationDataExt |
| 59 | +1. Download the result if need it |

| 162 | +Portable Document Format (PDF) is a type of document created by Adobe back in 1990s. The purpose of this file format was to introduce a standard for representation of documents and other reference material in a format that is independent of application software, hardware as well as Operating System. PDF files can be opened in Adobe Acrobat Reader/Writer as well in most modern browsers like Chrome, Safari, Firefox via extensions/plug-ins. Most of the commercially available software suites also offer conversion of their documents to PDF file format without the requirement of any additional software component. Thus, PDF file format has full capability to contain information like text, images, hyperlinks, form-fields, rich media, digital signatures, attachments, metadata, Geospatial features and 3D objects in it that can become as part of source document. |
