Pictures or Graphics are held on computers as files. The files can be in one of many formats.
There are lots of formats that have been around for ages - they are distinguished by the extensions
for the file names. The following list shows some of those extensions
BMP CLP CT CUT DCX DIB EPS FPX GIF IFF IMG JIF JPG KDC LBM MAC MSP PBM PCD PCT PCX PGM PIC PNG PPM PSD PSP RAS RAW RLE SCT TGA TIF WPG
The two main ones used for the internet are GIF and JPG files.
Internet browser programs have been told how to deal with such files. Browser are programmed to get their instructions from files containing HyperText Markup Language - in other words HTM files. If such files contain the names of GIF and JPG files, they are processed without any bother.
The layout and structure of HTM files is defined by the World Wide Web consortium, they are the authority for all things internet.
There are other files used for the Internet - an example is SWF files. They are known as ShockWaveFiles, they contain animations. Unfortunately the Internet Browser programs were written before ShockWaveFiles were dreamed of and therefore cannot handle them. To get around this problem, the producers of ShockWaveFiles created something called a Browser PlugIn. That is a program extension that enables browsers to deal with new file layouts.
The makers of Browser PlugIns usually provide a facility to download a copy of the PlugIn for free.
Now to SVG files !! The World Wide Web consortium, decided to develop and specify a new format for Graphics. That is the origin of the SVG (Scalable Vector Graphic) format. However the Internet Browsers cannot deal with such files, they have not been programmed to deal with them.
A company called Adobe have witten a Browser PlugIn that permits browsers to handle SVG files. The PlugIn can be downloaded from the Adobe SVG Zone - I downloaded it and installed it. It opened my eyes to a new vista of the world - it was well worth the effort !!
When you have loaded it, you may want to know more about SVG files. The World Wide Web consortium, web site is a source of such information - that is a bit technical and a bit hard work.
Another delightful site that is very interesting is SVG Spot - that was a place that really supported and kindled my interest and delight to have found Scalable Vector Graphics.
I found an SVG file that demonstrates some features of SVG files - it is not terribly exciting - so - I decided to "JazzIt Up" a bit, it may amuse you (keep an eye on the Yellow Spot - it is a real wicked little devil - hehehehe!!)
The web page that really really delighted me was Bella The Dragon, a Childrens Picture Book - I even downloaded it and have sat totally spellbound by it !!
You might even like to have a look at SVG Demos and try lots of the links.
It is hoped that you have found this page useful and/or interesting and maybe even informative. You may wish to comment below. (Didn't that yellow spot entertain you ??)
