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.
jp2 The JP2 file extension, also known as JPEG2000, was created by the JPEG Committee in the year 2000. The JP2 succeeded the first JPEG Standard in 1992 which was cosine transform based. It features the use of a "wavelet-base", unlike its predecessor JPEG standards. This file format uses a different image compression method. The compression method involves altering certain sections of the image, in terms of quality reduction. This method of compression ensures smaller file sizes and optimal storage. The JP2 file format has made several improvements over the JPEG Standard since 1992. The JP2 files can make use of both the lossless and lossy compression techniques.
