The target document should be PDF version 1.4. PDF is generally not suited for long term preservation. The PDF format may contain resources (such as fonts) that may not exist on the viewing machine. As a result, font substitution may occur resulting in a document that may not look exactly like the original version. | |
1 | PdfA |
The target document should be PDF/A-1b. PDF/A-1b is a subset of PDF obtained by leaving out PDF features not suited to long-term archiving. The resulting document is guaranteed to look exactly like the original version when viewed on the target machine. Saving with PDF/A document type may result in larger output file sizes. |
2 | Pdf12 |
The target document should be PDF version 1.2. PDF is generally not suited for long term preservation. The PDF format may contain resources (such as fonts) that may not exist on the viewing machine. As a result, font substitution may occur resulting in a document that may not look exactly like the original version. |
3 | Pdf13 |
The target document should be PDF version 1.3. PDF is generally not suited for long term preservation. The PDF format may contain resources (such as fonts) that may not exist on the viewing machine. Hence font substitution may occur resulting in a document that may not look exactly like the original version. |
4 | Pdf15 |
The target document should be PDF version 1.5. PDF is generally not suited for long term preservation. The PDF format may contain resources (such as fonts) that may not exist on the viewing machine. As a result font substitution may occur resulting in a document that may not look exactly like the original version. |
5 | Pdf16 |
The target document should be PDF version 1.6. PDF is generally not suited for long term preservation. The PDF format may contain resources (such as fonts) that may not exist on the viewing machine. As a result font substitution may occur resulting in a document that may not look exactly like the original version. |
LEADTOOLS Document Writers can create different types of Adobe PDF documents. You can specify the PDF document type through the use of the PdfDocumentOptions.DocumentType property.
