Calibre 0.8.67 released with support for mathematic operations and dedicated image view

Calibre is a versatile e-book library management tool that, along with a powerful e-book viewer, comes with numerous functionalities (file format conversion, in-depth detail editing, online news fetching, etc).

Calibre 0.8.67 has been released, introducing (since 0.8.66) the handy support to display mathematical operations, such as numerous symbols, fractions, matrices, equations, etc.

The math-related operations can be displayed (are supported) in EPUB and HTML files.

Basically, if a HTML file contains (the "old" behavior)

the Calibre viewer will render it as (the new behavior)

The users can benefit the newly added feature in cases like downloading a HTML file filled with mathematics and open it directly with Calibre (Calibre 0.8.67 will expose the math operations as user-friendly operations), and/or downloading a HTML file containing math operations, and convert it to EPUB, followed by distributing the created EPUB file to various persons, etc.

In order to accurately render mathematical operations, Calibre uses MathJax, a high-quality open-source engine focused on mathematics.

Calibre features a solid library where numerous books can be added, sometimes including books that contain maps, complex images, image-based chemical reactions, etc, book types that sometimes "demand" (for a proper reading experience) a manner of exposing an image into a separate window while scrolling the book's text content (in situations like observing a map while reading the history of a certain culture, following a map while reading details about the species living across a certain continent, etc); the mentioned functionality has been implemented into Calibre, meaning, the user can open an image (in a dedicated separate window) while "moving" through pages, pages and separately displayed image contained in the same book.

The usage is a simple as opening a book, navigate to the preferred image and right-click on the image-->View image, action that separates the image into a distinct "frame".

Along with the mentioned features, Calibre 0.8.67 brings various fixes and optimizations (option to select the used font's "family" and size when on PDF conversion, enhanced Metadata dialog, etc), as well as new news sources (Arcadia, CIPER, Business Week Magazine, Chronicle of Higher Education, etc).
