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. *''Readers'' – 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 ...

Software
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU General Public License
The GNU General Public License (GNU GPL or simply GPL) is a series of widely used free software licenses that guarantee end users the Four Freedoms (Free software), four freedoms to run, study, share, and modify the software. The license was the first copyleft for general use and was originally written by the founder of the Free Software Foundation (FSF), Richard Stallman, for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. These GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. It is more restrictive than the GNU Lesser General Public License, Lesser General Public License and even further distinct from the more widely used permissive software licenses BSD licenses, BSD, MIT License, MIT, and Apache License, Apache.

Inkscape
Inkscape is a free and open-source vector graphics editor used to create vector images, primarily in Scalable Vector Graphics (SVG) format. Other formats can be imported and exported. Inkscape can render primitive vector shapes (e.g. rectangles, ellipses, polygons, arcs, spirals, stars and 3D boxes) and text. These objects may be filled with solid colors, patterns, radial or linear color gradients and their borders may be stroked, both with adjustable transparency. Embedding and optional tracing of raster graphics is also supported, enabling the editor to create vector graphics from photos and other raster sources. Created shapes can be further manipulated with transformations, such as moving, rotating, scaling and skewing. History Inkscape began in 2003 as a code fork of the Sodipodi project. Sodipodi, developed since 1999, was itself based on Raph Levien's Gill (GNOME Illustration Application). One of the main priorities of the Inkscape project was interface consistency an ...

Mobipocket
Mobipocket SA was a French company incorporated in March 2000 that created the .mobi e-book file format and produced the Mobipocket Reader software for mobile phones, personal digital assistants (PDA) and desktop operating systems. The Mobipocket software package was free and consisted of various publishing and reading tools for PDAs, smartphones, mobile phones, the e-readers Kindle and iLiad, and applications on devices using Symbian, Windows, Palm OS, Java ME and Psion. Amazon.com bought Mobipocket.com in 2005 and kept it running until October 2016, when it permanently shut down the Mobipocket website and servers. History Amazon.com bought Mobipocket.com in 2005. Amazon's acquisition was believed to be a result of Adobe Systems' announcement that it would no longer sell its eBook-packaging and -serving software. An alpha release of the Java-based version of the Mobipocket reader became available for cellphones on June 30, 2008. There is also a reader for desktop compute ...

Smallpdf
Smallpdf is a Swiss online web-based PDF software, founded in 2013. It offers free services to compress, convert and edit PDF documents. History Smallpdf was founded in 2013 by Mathis Büchi, Lino Teuterberg, and Manuel Stofer while they were living abroad in Korea. The idea came from the need for their families to compress and send large documents via email. The initial version of the site featured a standalone PDF compression tool. Since then, the online platform has introduced over 16 PDF tools to convert, compress and edit PDF documents. As of 2019, approximately 25 million unique users use Smallpdf every month. In November 2018, it was announced that Smallpdf would integrate with Dropbox as part of the 'Dropbox Extensions', to provide Dropbox users with PDF editing capabilities. Technical partners Smallpdf partners with Solid Documents for PDF to Office libraries, as well as with PDF tools. Solid Documents is a New Zealand-based company offering desktop PDF solutions. ...

Xpdf
Xpdf is a free and open-source PDF viewer for operating systems supported by the Qt toolkit. Versions prior to 4.00 were written for the X Window System and Motif. Functions Xpdf runs on nearly any Unix-like operating system. Binaries are also available for Windows. Xpdf can decode LZW and read encrypted PDFs. The official version obeys the DRM restrictions of PDF files, which can prevent copying, printing, or converting some PDF files. There are patches that make Xpdf ignore these DRM restrictions, and these restrictions are patched out by the Debian distribution. Xpdf includes several programs that don't need an X Window System, including some that extract images from PDF files or convert PDF to PostScript or text. These programs run on DOS, Windows, Linux and Unix. Xpdf is also used as a back-end for other PDF readers frontends such as KPDF and GPDF, and its engine, without the X11 display components, is used for PDF viewers including BePDF on BeOS, '!PDF' on RISC OS, on ...

QPDF
QPDF is both a software library and a free command-line program that can convert one PDF file to another equivalent PDF file. It is capable of performing transformations such as linearization (also known as web optimization or fast web viewing), encryption, and decryption of PDF files. It also has options for inspecting or checking PDF files, some of which are useful primarily to PDF developers. QPDF includes support for rotating, merging and splitting PDFs through the ability to copy objects from one PDF file into another and to manipulate the list of pages in a PDF file. QPDF is not capable of converting PDF into other formats. The QPDF library also makes it possible to create PDF files from scratch. In this mode, the user is responsible for supplying all the contents of the file, while the QPDF library takes care of the syntactical representation of the objects, creation of cross references tables and, optionally, object streams, encryption, linearization, and other syntactic ...

Vector Graphics
Vector graphics is a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing ''hardware'', vector ''data models'' and file formats, as well as the ''software'' based on these data models (especially graphic design software, computer-aided design, and geographic information systems). Vector graphics is an alternative to raster or bitmap graphics, with each having advantages and disadvantages in specific situations. While vector hardware has largely disappeared in favor of raster-based monitors and printers, vector data and software continues to be widely used, especially when a high degree of geometric precision is required, and when complex information can be decomposed into simple geometric primitives. Thus, it is the preferred model for domains such as engineering, architecture, surveying, 3D render ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pstoedit
pstoedit is a free computer program that converts PostScript and PDF files to other vector formats. It supports many output formats, including WMF/EMF, PDF, DXF, CGM, and HTML, and by means of free/shareware plugins SVG, MIF and RTF. The author and maintainer is Wolfgang Glunz. pstoedit uses ghostscript to perform the first part of the conversion process. Ghostscript converts the PostScript (or PDF) file to a more basic PostScript format, translating complex functions to basic functions, such as line draw commands. The second part of the conversion process consists of translating these basic functions into basic functions of the output format. pstoedit is multi platform. For MS Windows, a setup program is available for both 32bit and 64bit, which does the complete job (including for instance making the connection with ghostscript and MS Office). Three interfaces can be installed: the command line interface, an interface by means of gsview and an import filter for MS Offic ...
