|Description||The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it.||The .pdb file extension is a database format used for the Palm OS platform. The PalmDOC eBook file type is a version of the PDB format. The proliferation of eBooks has left this format behind due to the lack of support for DRM protection meaning only royalty free text is typically available.|
|Technical details||The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. A font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate.||The format supports reflowable content however the format lacks some of the features found in more modern eBook formats, for example only providing a very basic contents table. The format features RLE compression which was crucial because the format was designed for the low storage capacity Palm devices of the 1990s.|
