Description |
Portable Document Format (PDF) is a file format created by Adobe Systems in 1993 for document exchange. PDF is used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system. Each PDF file encapsulates a complete description of a fixed-layout 2-D document (and, with Acrobat 3-D, embedded 3-D documents) that includes the text, fonts, images, and 2-D vector graphics which comprise the documents. |
JPEG 2000 is a wavelet-based image compression standard. The aim of JPEG 2000 is not only improved compression performance over JPEG but also adding (or improving) features such as scalability and editability. |
