PDF is a standard for encoding documents in an "as printed" form that is portable between systems. However, the suitability of a PDF file for archival preservation depends on options chosen when the PDF is created: most notably, whether to embed the necessary fonts for rendering the document; whether to use encryption; and whether to preserve additional information from the original document ...
Interactive Forms is a mechanism to add forms to the PDF file format. PDF currently supports two different methods for integrating data and PDF forms. Both formats today coexist in the PDF specification: [38] [53] [54] [55] AcroForms (also known as Acrobat forms), introduced in the PDF 1.2 format specification and included in all later PDF ...
The early File Transfer Protocol (FTP) is considerably less transparent, because it requires each user to learn how to access files through an ftp client. Similarly, some file systems allow transparent compression and decompression of data, enabling users to store more files on a medium without any special knowledge; some file systems encrypt ...
The Portable Document Format (PDF) was created by Adobe Systems, introduced at the Windows and OS/2 Conference in January 1993 and remained a proprietary format until it was released as an open standard in 2008.
Some image formats, such as PNG and TIFF, also allow partial transparency through an alpha channel, which solves the edge limitation problem. Instead of each pixel either being transparent or not transparent, it can be set to 254 levels of partially transparent, allowing some of the background image to show through the foreground image.
This means that when an MP3 that was encoded at those bitrates is being played back, it is indistinguishable from the original PCM, and the compression is transparent to the listener. The term transparent compression can also refer to a filesystem feature that allows compressed files to be read and written just like regular ones. In this case ...
Modern usage of the term radical transparency coincided with increased public use of Information communications technologies including the Internet. Kevin Kelly argued in 1994 that, “in the network era, openness wins, central control is lost.” [3]: p.116 David Brin's writing on The Transparent Society re-imagined the societal consequences of radical transparency remixing Orwell's 1984.
WWF is a modification of the open standard PDF format for document exchange endorsed by the World Wide Fund for Nature (also abbreviated WWF) Germany. [1] The WWF format is promoted as being more environmentally friendly than other comparable document exchange formats (e.g. PDF or DOC) since documents in this format are designed to be more difficult to print.
