MuPDF
MuPDF is a free and open-source software framework written in C that implements a PDF, XPS, and EPUB parsing and rendering engine. It is used primarily to render pages into bitmaps, but also provides support for other operations such as searching and listing the table of contents and hyperlinks. The focus of MuPDF is on speed, small code size, and high-quality anti-aliased rendering. Since the 1.2 release, MuPDF has optional support for interactive features such as form filling, JavaScript and transitions. The library ships with a rudimentary X11 and Windows viewer, and a set of command-line tools for batch rendering (mutool draw), examining the file structure (mutool show), and rewriting files (mutool clean). Later versions also have a JavaScript interpreter (mutool run) that allows running scripts to create and edit PDF files. A number of free software applications use MuPDF to render PDF documents, the most notable being Sumatra PDF. MuPDF is also available as a package f ...

List Of PDF Software
This is a list of links to articles on software used to manage Portable Document Format (PDF) documents. The distinction between the various functions is not entirely clear-cut; for example, some viewers allow adding of annotations, signatures, etc. Some software allows redaction, removing content irreversibly for security. Extracting embedded text is a common feature, but other applications perform optical character recognition (OCR) to convert imaged text to machine-readable form, sometimes by using an external OCR module. Terminology *''Creators'' – to allow users to convert other file formats to PDF. *''Viewers'' – to allow users to open, read and print PDF files. *''Editors'' – to allow users to edit or otherwise modify PDF files. *''Converters'' – to allow users to convert PDF files to other formats. Multi-platform Development libraries These are used by software developers to add and create PDF features. Creators These create files in their native formats, b ...

Sumatra PDF
Sumatra PDF is a free and open-source document viewer that supports many document formats including: Portable Document Format (PDF), Microsoft Compiled HTML Help (CHM), DjVu, EPUB, FictionBook (FB2), MOBI, PRC, Open XML Paper Specification (OpenXPS, OXPS, XPS), and Comic Book Archive file (CB7, CBR, CBT, CBZ). If Ghostscript is installed, it supports PostScript files. It is developed exclusively for Microsoft Windows. Features Sumatra has a minimalist design, with its simplicity attained at the cost of extensive features. For rendering PDFs, it uses the MuPDF library. Sumatra was designed for portable use, as it consists of one file with no external dependencies, making it usable from an external USB drive, needing no installation. This classifies it as a portable application to read PDF, XPS, DjVu, CHM, eBooks (ePub, FictionBook, Mobi PDB and TCR), Comic Book (CBZ, CBR, CBT, and CB7) and image formats ( BMP, GIF, JPEG, JPEG 2000, JPEG XR, PNG, TGA, and WebP).

Open XML Paper Specification
Open XML Paper Specification (also referred to as OpenXPS) is an open specification for a page description language and a fixed-document format. Microsoft developed it as the XML Paper Specification (XPS). In June 2009, Ecma International adopted it as international standard ECMA-388. It is an XML-based (more precisely XAML-based) specification, based on a new print path (print processing data representation and data flow) and a color-managed vector document format that supports device independence and resolution independence. In Windows 8 .xps was replaced with the ECMA standard .oxps format which is not natively supported in older Windows versions. OpenXPS was introduced by Microsoft as an alternative to Portable Document Format (PDF). However, PDF remained the standard choice, and support for and user familiarity with XPS files is limited. It has been described as neglected technology, which may cause difficulties to recipients of documents in a format they are not fa ...

EPUB
EPUB is an e-book file format that uses the ".epub" file extension. The term is short for ''electronic publication'' and is sometimes stylized as ''ePUB''. EPUB is supported by many e-readers, and compatible software is available for most smartphones, tablets, and computers. EPUB is a technical standard published by the International Digital Publishing Forum (IDPF). It became an official standard of the IDPF in September 2007, superseding the older Open eBook (OEB) standard. The Book Industry Study Group endorses EPUB 3 as the format of choice for packaging content and has stated that the global book publishing industry should rally around a single standard. Technically, a file in the EPUB format is a ZIP (file format), ZIP archive file consisting of XHTML files carrying the content, along with images and other supporting files. EPUB is the most widely supported vendor-independent XML-based e-book format; it is supported by almost all hardware readers and many software readers a ...

Poppler (software)
Poppler is a free and open-source software library for rendering Portable Document Format (PDF) documents. Its development is supported by freedesktop.org. Commonly used on Linux systems, it powers the PDF viewers of the GNOME and KDE desktop environments. History The project was started by Kristian Høgsberg with two goals: to provide PDF rendering functionality as a shared library, to centralize maintenance effort and to go beyond the goals of Xpdf, and to integrate with functionality provided by modern operating systems. By the version 0.18 release in 2011, the poppler library represented a complete implementation of ISO 32000-1, the PDF format standard, and was the first major free PDF library to support its forms (only Acroforms but not full XFA forms) and annotations features. Poppler is a fork of Xpdf-3.0, a PDF file viewer developed by Derek Noonburg of Glyph and Cog, LLC. The name ''Poppler'' comes from " The Problem with Popplers," an episode of the animated serie ...

Research And Development
Research and development (R&D or R+D), known in some countries as OKB, experiment and design, is the set of innovative activities undertaken by corporations or governments in developing new services or products. R&D constitutes the first stage of development of a potential new service or the production process. Although R&D activities may differ across businesses, the primary goal of an R&D department is to new product development, develop new products and services. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. R&D is crucial for acquiring larger shares of the market through new products. ''R&D&I'' represents R&D with innovation. Background New product design and development is often a crucial factor in the survival of a company. In a global industrial landscape that is changing fast, firms must continually revise their design and range of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Ghostscript
Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages. Its main purposes are the rasterization of documents in these language,, the display or printing of document pages, and conversion between PostScript and PDF files. Features Ghostscript can be used as a raster image processor (RIP) for raster computer printers—for instance, as an input filter of line printer daemon—or as the RIP engine behind PostScript and PDF viewers. It can also be used as a file format converter, such as PostScript to PDF converter. The ps2pdf conversion program comes with the Ghostscript distribution. Ghostscript can also serve as the back-end for PDF to raster image (png, tiff, jpeg, etc.) converter; this is often combined with a PostScript printer driver in " virtual printer" PDF creators. As it takes the form of a language interpreter, Ghostscript can also be used as a general purpose programming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Copyright Infringement
Copyright infringement (at times referred to as piracy) is the use of Copyright#Scope, works protected by copyright without permission for a usage where such permission is required, thereby infringing certain exclusive rights granted to the copyright holder, such as the right to reproduce, distribute, display or perform the protected work, or to produce derivative works. The copyright holder is usually the work's creator, or a publisher or other business to whom copyright has been assigned. Copyright holders routinely invoke legal and technological measures to prevent and penalize copyright infringement. Copyright infringement disputes are usually resolved through direct negotiation, a notice and take down process, or litigation in Civil law (common law), civil court. Egregious or large-scale commercial infringement, especially when it involves counterfeiting, or the fraudulent imitation of a product or brand, is sometimes prosecuted via the criminal justice system.

GNU General Public License
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software (FOSS) domai ...
