开源办公软件，Calligra 2.7 发布
Calligra 是一套开放 源代码的办公室套装软件，可用于Linux、Mac OS X、Windows 和 Haiku等操作系统。其中包含了多种软件，包括：文字处理器、电子数据表、演示稿软件、数据库管理，以及矢量图形和数字绘图软 件。Calligra 使用开放文件格式（ODF，OpenDocument Format）作为默认的文件格式，并能导入其他格式，如Microsoft Office的文件。Calligra依赖于KDE技术，并常与KDE Software Compilation相结合。
Calligra Suite的前身是KOffice，其开发开始于1997年。在1998年加入KPresenter和KWord。
The Calligra team is proud and pleased to announce the release of version 2.7 of the Calligra Suite, Calligra active and the Calligra Office Engine. This version is the result of thousands of commits which provide new features, polishing of the user interaction and bug fixes.
The version number of this release is actually 2.7.1, not 2.7.0 because a serious problem was found after the tagging of 2.7.0. Due to the release process, the team had to withdraw 2.7.0 and instead release 2.7.1 as the first stable version of the 2.7 series.
News in This Release
Calligra 2.7 contains a number of new features. Here is an excerpt of the most important ones.
Words, the word processing application, has a new look for the toolbox. In the same toolbox there are also new controls to manipulate shapes with much enhanced usability. Styles are now sorted with the used ones first in the style selector which should make using styles much more convenient. There are also enhancements to the reference controls, especially regarding hyperlinks and bookmarks.
Author, the writer’s application, has new support for EPUB3: mathematical formulas and multimedia contents are now exported to ebooks using the EPUB format. There is also new support for book covers using images.
The new toolbox for Words, Author, Sheets and Stage inside the sidebar.
There is a new export filter for common text and enhancements to the docx import filter, which can now support predefined table styles. Note that all of these enhancements to Words and Author are also available in the other application. We note here where they were originally developed.
Sheets, the spreadsheet application, now uses the same new toolbox as Calligra Words.
Plan, the project management application, has improvement in the scheduling of tasks and new export filters to OpenDocument Spreadsheet (ODS) and CSV.
Kexi, the visual database creator, improves CSV data import, in particular now it can import data into an existing table. Passwords do not require modal dialogs and are generally better handled. See the full list of changes.
Shapes: There are some improvements in the general shapes available from most Calligra applications: The formula shape now has new ways to enter formula: a matlab/octave mode and a LaTEX mode. The tool for the text shape is improved to better handle text styles.
Another change common to Words, Author and Stage is an improved visual style editor.
The new shape editor, also known as shape control.
Krita, the 2D paint application, has new grayscale masks, a better freehand path tool with line smoothing, a way to paint shapes with Krita brushes, improved color to alpha filter, an improved crop tool and an improved transform tool that helps the user create textures. Support for new file formats include export to QML and a much improved import/export filter for photoshop PSD files. You can read about the improvements in Krita in more details on krita.org.
