These versions include special TouchUp properties to manage digits, ligatures option and paragraph direction in right-to-left Middle Eastern scripts such as Arabic, Hebrew, and Persian, as well as standard left-to-right Indian scripts such as Devanagari and Gujarati.
The Web Capture feature can convert single web pages or entire web sites into PDF files, while preserving the content's original text encoding.
Acrobat can also copy Arabic and Hebrew text to the system clipboard in its original encoding; if the target application is also compatible with the text encoding, then the text will appear in the correct script.
A comprehensive list of security bulletins for most Adobe products and related versions is published on their Security bulletins and advisories page and in other related venues. From Version 3. This functionality allows a PDF document creator to include code which executes when the document is read. Malicious PDF files that attempt to attack security vulnerabilities can be attached to links on web pages or distributed as email attachments.
While JavaScript is designed without direct access to the file system to make it 'safe', vulnerabilities have been reported for abuses such as distributing malicious code by Acrobat programs.
Since at least version 6, JavaScript can be disabled using the preferences menu [41] and embedded URLs that are launched are intercepted by a security warning dialog box to either allow or block the website from activating. These vulnerabilities could cause the application to crash and potentially allow an attacker to take control of the affected system. There have been reports of these vulnerabilities being exploited to trick Windows users into clicking on a malicious PDF file delivered in an email message.
Adobe recommended users update their product installations. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system.

Converting to such an old standard is also difficult: what do you do with all the things present in your PDF files that are not possible within a PDF 1.
Using ghostscript I managed to output pdf 1. Specifying 1. I just tried with MS Word on Mac, and it was version 1. Pages on the same Mac created a PDF to the 1. You can convert any PDF to any version. Hi, I have a question. So from when was this possible to do? That has been possible for as long as I remember. What has improved over time is the ability to select a block of text.
Hi, I have a question here. Will it affected the space between the paragraph if using different version of PDF to download or print out the documents. Example, if i open and print the file by using my laptop and using my handphone to do the same things, will it be a differences? If yes, is it because of the version of PDF? Can two applications display a PDF differently? If you open a recent PDF with an old viewing application, the program might not be able to interpret all the functions that newer versions of PDF can use.
Some page elements might simply not be shown. This is the reason why in graphic arts it is customary to always use Adobe Reader or Adobe Acrobat. Those applications have proven to be the most reliable for correctly displaying complex PDF files.
Other software can be just as good when it comes to viewing simple office documents but for print-ready PDF files used by designers, creative agencies and printers, the Adobe software is the way to go.
If you open a PDF in one copy of Adobe Acrobat that is configured to show overprints and then in another copy on another machine where that setting is disabled, some text or other elements may be shown differently.
If it is not created correctly and has missing font data, one viewer might use font A to display the text and another PDF viewer might use font B. Missing font data is typically the reason why the spacing between characters on a line of text looks different in two different PDF viewers. I have never actually seen the spacing between paragraphs, so the height between one line of text and the next one, change. Your email address will not be published.
