svgz The .svgz extension files are Scalable Vector Graphics files that have been compressed using the GZIP compression. These files support graphical elements that include transparency, animations, gradients and filters. They consist of graphics data that is put together in an XML format. Images, text and vector graphic shapes which are paths that comprise of curves and straight lines are the three kinds of graphic objects allowed by .svg extension format. Excellent dynamic and interactive images can be created using the Scalable Vector Graphics technology which has been developed by W3C (World Wide Web Consortium) SVG group in 1998 and launched in 1999. It has been used by many web designers since then for attractive graphical representation. As per W3C recommendation, SMIL is the right choice for SVG when it comes to animation. Onmouseover or Onclick assignments can also be configured for objects in the SVG graphics to handle specific animation events to make the image dynamic and interactive.
pdf The .pdf file format extension was developed by Adobe systems in 1993 as a means of presenting documents in a consistent manner across different platforms, hardware, operating systems, and applications. The format was not released as an open source document format until 2008, though minimal proprietary technologies still controlled by Adobe Systems exist in the format. Every .pdf document carries with it the necessary meta information required to properly reconstruct the text, fonts, and graphics used to produce the document. This ensures that documents will be viewed in exactly the same way the author intended regardless of the device used to open the document. From conception to date, Adobe Systems has continued to support the format adding features with every iteration of the standard including hardened algorithms for document encryption and privacy. Today, many freely available readers exist allowing you to open and view .pdf documents and create or convert other file formats such as .jpeg and .doc into .pdf documents.
