ប្រវត្តិកំណើត[កែប្រែ]

ការ​ចេញ​ផ្សាយ​ដំបូង[កែប្រែ]

On 28 September 2010, several members of the OpenOffice.org project formed a new group called "The Document Foundation". The Document Foundation created LibreOffice from their former project, over concerns that Oracle Corporation would either discontinue OpenOffice.org, or place restrictions on it as an open-source project, as it had on OpenSolaris.

It was originally hoped that the LibreOffice name would be provisional, as Oracle was invited to become a member of The Document Foundation. Oracle rejected offers to donate the OpenOffice.org brand to the project[១២] and demanded that all members of the OpenOffice.org Community Council involved with The Document Foundation step down from the OOo community council, citing a conflict of interest.[១៣]

The Go-oo project was discontinued in favour of LibreOffice.[១៤] Improvements made by the project are being merged into LibreOffice. Improvements made in other forks are also expected to be incorporated into LibreOffice.[១៥][១៦] Other improvements being made is the use of Java is being reduced to reduce any possible security issue and to improve application stability.[១៧]

As a result of the fork of OpenOffice.org into LibreOffice, and the resulting loss of developers, Oracle announced in April 2011 that it was terminating the commercial development of OpenOffice.org.[១៨]

កំណែ 3.3[កែប្រែ]

Impress in LibreOffice 3.3.0

LibreOffice 3.3.0 Beta 1, which was based on the beta release of OpenOffice.org 3.3, was made available on 28 September 2010 - the day "The Document Foundation" was announced to act as the suite's public figurehead. The first stable version, 3.3, was released on 25 January 2011.[១៩] Because The Document Foundation and most of the software's developers saw LibreOffice as being a direct continuation of OpenOffice.org, LibreOffice 3.3 continued the OpenOffice.org version numbering.

LibreOffice 3.3 features several functions not found in its OpenOffice.org counterpart, mainly as a result of Oracle's copyright assignment policies. Most of the features found in the 3.3 release were directly adapted from several already-created plugins, as well as the Go-oo fork. Among features unique to LibreOffice are:[២០]

  • SVG image import.
  • Lotus Word Pro and MS Works import filters.
  • Improved WordPerfect import.
  • Dialog box for title pages.
  • Navigator lets one heading be unfolded as usual in a tree view.
  • "Experimental" mode that allows unfinished features to be tried by users.
  • Some bundled extensions, including Presenter View in Impress.
  • Colour-coded document icons.

កំណែ 3.4[កែប្រែ]

The major release of LibreOffice following 3.3 is version 3.4, released on 3 June 2011.[២១][២២] Although in final form, v3.4 is stated on the LibreOffice website to be suitable for early adopters[២៣], with known issues.[២៤] Hence, v3.3.3 is still available for others. In particular, v3.4 has known compatibility issues with Microsoft Office.[២៤] New features and improvements said to be in 3.4 include:[២៥]

  • Memory usage improvements.[២៦]
  • Reduction of LibreOffice's reliance on Java.[២៦]
  • Continuing the transition to GNU MAKE for building LibreOffice.[២៧]
  • A change of style can be tested and, if unsuitable, simply be "reset" in Writer's style edit dialog, with no need to close the style dialog to check the new style.[២៨]
  • Improvements to Calc, including improved speed and improved compatibility with Microsoft Excel, including pivot tables (formerly called DataPilot in OOo/LOo), support for an unlimited number of fields.[២២]
  • Improved user interface for Writer, Impress and Draw, including better text rendering engine and improved GTK+ theme integration in Linux.[២២]
  • Several thousand lines of German comments were translated into English and over 5,000 lines of dead code were removed from Writer, Calc and Impress.[២២]

លក្ខណៈ​ពិសេស​ទូទៅ[កែប្រែ]

Unlike OpenOffice.org, LibreOffice uses the GStreamer multimedia framework in Linux to render multimedia content such as videos in Impress and other programs. Visually, LibreOffice uses the large "Tango style" icons that are used for the application shortcuts, quick launch icons, icons for associated files and for the icons found on the toolbar of the LibreOffice programs.[២៩][៣០] They are also used on the toolbars and menus by default. OpenOffice.org uses small icon sizes and the "Classic" or "Galaxy" icon style by default.[២៩][៣១][៣២] Also, LibreOffice uses a combo box in place of the zoom button found in OpenOffice.org and not a zoom slider. The first run wizard from OpenOffice.org that guides a user through the setting of user name and the registration process has been removed from LibreOffice. [៣៣]

ពេល​កំណត់​ការ​ចេញ​ផ្សាយ[កែប្រែ]

Table showing the release cadence

The Document Foundation intends to release new major versions of LibreOffice once every six months and to eventually align with the March/September schedule of the other major free software projects.[២១]

The Foundation provides two different versions of LibreOffice. The latest version is available for users looking for the latest enhancements while the previous version caters to users who prefer stability over availability of new features.[៣៤]

ប្រភេទ​ឯកសារ​ដែល​ស្គាល់[កែប្រែ]

LibreOffice can import and export documents in several file formats;[៦] its native format is the OpenDocument Format. Formats supported (for reading and writing) include those used by Microsoft Office, including the Office Open XML specification used in Microsoft Office 2007 and 2010, which use the .docx, .pptx and .xlsx extensions, as well as to the older file formats used in Microsoft Office 95 and 97-2003, which use .doc, .ppt and .xls. Also supported are Rich Text File format and OpenOffice.org XML format.[ត្រូវការអំណះអំណាង] LibreOffice can save password-protected XLS files. It uses only one basic encryption method compatible with many spreadsheet applications (for example Gnumeric).

LibreOffice has VBA macro support. It can import files from MS Works and Lotus Word Pro. LibreOffice Draw has native functionality to open SVG files, where OpenOffice.org Draw requires an extension.[៣៥][៣៦][៣៧] There is improved EMF drawing and WordPerfect Graphics import.

Exporting to a number of non-editable formats is supported. All documents can be exported to the PDF format,[៦] and presentations to Adobe Flash (SWF). LibreOffice also has the ability to import documents in read-only mode in the Unified Office Format, Data Interchange Format and the formats of Microsoft Works, WordPerfect, Lotus 1-2-3, and others.[ត្រូវការអំណះអំណាង].
