Adobe Acrobat is a family of Application Software by Adobe Systems . These applications use Adobe's Portable Document Format (PDF) as their native File Format . Some software in the family is commercial, and some free of charge. '''Adobe Reader''' (formerly called '''Acrobat Reader''') is available as a no-charge download from Adobe's web site, and allows the viewing and printing of PDF files. Acrobat and Reader are major components of the Adobe Engagement Platform , and are widely used as a way to present information with a fixed layout similar to a paper publication. The Adobe Acrobat products are . Retrieved on 2007-06-18 .. HISTORY Since the early 1990s , the Acrobat product had several competitors who each used their own document formats, such as:
By the late 1990s PDF had become the De Facto standard, and the others had become largely historical footnotes. This in turn has led to many more competitors for Adobe Acrobat, both free and commercial. Today, there are a host of third-party programs that create or manipulate PDF, such as Ghostscript , Foxit , and Nitro PDF . Adobe also allows Acrobat plug-ins to be developed by third parties, which can add extra functions within the Acrobat program. Product names Adobe has changed the names of the products in the Acrobat family regularly, also splitting products up, joining them together, or discontinuing members. This causes much confusion, not only about what product to obtain, but even about what product people have. Between version 3 and 5, Standard and Professional versions were one product simply called Adobe Acrobat. As of April 2007, the current main members of the Adobe Acrobat family are
Adobe has never created a product called either Adobe Writer or Acrobat Writer, although these names seem a natural opposite to the Reader product. To add more confusion, Acrobat used to include a Printer Driver called PDFWriter, which is unrelated. Product history Acrobat Reader 1.0 for Macintosh was originally released 15 June 1993, later for DOS and Windows 3.1. This was not available in single copies and was not initially free. After a while the IRS purchased a right to distribute Reader 1.0, effectively making it seem free to those who obtained it that way.
Acrobat Reader 2.0 for Windows and Macintosh was released September 1994. Now free.
Acrobat Reader 3.0 was released 1996. The first to display PDF files in-browser, and the first to support form filling.
Acrobat Reader 4.0 was released April 1999.
Acrobat Reader 5.0 was released May 2001.
Adobe Reader 6.0 was released April 2003. No Linux or Unix versions were released.
Adobe Reader 7.0 was released January 2005.http://www.adobe.com/aboutadobe/pressroom/pressreleases/200501/010505Acrobat.html
]] Adobe Reader 8.0 was released November 2006.http://www.adobe.com/aboutadobe/pressroom/pressreleases/200609/091806Acrobat.html
On June 2007, an update for Acrobat 8 Professional and Adobe Reader 8.1 was released in order to support Microsoft Office 2007 , Windows Vista and 64 bit Windows Operating Systems . (version 8.1) CRITICISMS From Version 3.02 onwards, Acrobat Reader (now Adobe Reader) has included support for JavaScript . This functionality allows the document creator to include code which executes when the document is read. 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 through Acrobat.1 On September 13 , 2006 , David Kierznowski provided sample PDF files illustrating these vulnerabilities. In the most current version of Reader, JavaScript can be disabled using the preferences menu and embedded URLs that are launched are intercepted by a security warning dialog box to either allow or block the website from launching.2 There have been a number of people who consider the software to be too slow to load and use,http://searchenginewatch.com/showPage.html?page=3456481 so they have developed work around solutions to speed up the software.http://underscorebleach.net/jotsheet/2005/01/fix-adobe-acrobat-pdf-problems The application has been improved by Adobe as the latest version of the software does load quicker; Adobe claims that Adobe Reader 7 users can "Open and save PDF files faster than ever" as version 7.0 launches "up to 50% faster than version 6.0".http://www.adobe.com/products/acrobat/acrrwhatsnew.html This works by installing a program which runs every time the computer is turned on, and which loads parts of Reader into memory. This can sometimes improve the loading speed of Reader, but also uses up valuable memory resources on the computer and causes longer start-up times. A typical install size is 96MB. Many have also noted poor behavior in the Internet Explorer and Mozilla Firefox Acrobat plug-ins. The plug-ins do not support full asynchronous loading, thus causing browsers to appear to "lock up" until the document has been fully downloaded. To make matters worse, they apparently also fail to terminate when a document is closed, thereby leaving behind various CPU-intensive application threads that run until the next reboot.http://www.file.net/process/acrord32.exe.html Adobe has also refused to support past versions (version prior to version 8 - their latest) under Windows Vista. Anyone purchasing a new computer must either sacrifice using Adobe PDF tools, step back to Windows XP, or pay an upgrade fee to version 8 to be able to continue using Adobe products. |
