Types of PDF |
|||||||||
|
There are three types of PDF document - They are: |
|||||||||
|
Formatted Text & Graphics |
|||||||||
|
This type of PDF preseerves the text of a document and a graphic bit map for all non-text items. Where the original document is a scanned image this method necessitates manual correction of the OCR’d ( Optical Character Recognition ) text. |
|||||||||
|
The main advantage is that the process of conversion is less costly. |
|||||||||
|
PDF Searchable |
|||||||||
|
In this format it is possible to view an exact image of the document whilst being able to search the Text produced by OCR. The Text however can not be edited it is for indexing only. There is a low level of manual correction required and so the cost is reduced however because of the retention of full images this format takes up more memory. |
|||||||||
|
This has to offset against the advantage of having an accurate image of the original which is invaluable where the document may be required in a dispute situation |
|||||||||
|
Image only |
|||||||||
|
This is as above but without any OCR produced text for search purposes. This disadvantage can often be minimised by the use of book marks, subject or keyword fields to provide a system of indexing. In some applications this produces a more useful method of searching for individual batches of documents. |
