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.
gif The .gif filename extension refers to the GIF graphical file format created by CompuServe in 1987. The format is from the class of raster graphics which uses a dot matrix type data structure of orthogonally placed pixels, each with their own color information. The file format has a rich history of usage in storing sprite data for video games especially those released in the early 90's. The GIF format has also been used in low-resolution animation clips distributed over the internet, and in design of sharp-edged art that utilize a palette of a few colors up to a max of 256 colors. The GIF file format has its advantage in its compression technique, which limits file size but does not compromise image quality. The file format natively opens on many of the popular web browsers.
