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.
pcx The Picture Exchange file format, shortened PCX, with the .pcx filename extension is an image file format developed by ZSoft Corporation. It was initially released in 1985 as a lossless bitmap image format and for a time was the default file format for PC paintbrush. The format is now largely superseded by other formats given the target platforms for the software associated with the format are no longer in production, i.e. MS DOS and Windows 1.0.
