SVG Basic (SVGB)  is a subset of SVG, and SVG Tiny (SVGT) is a subset of SVG 

Basic.  These  light  versions  of  SVG  are  designed  to  accommodate  cellphones  and 

other handheld devices with limited screen real estate, memory and bandwidth. SVGT 

is  the  format  involved  in  the  implementation  of  this  thesis.  The  theoretical  issues  of 

SVGT are discussed as following.   

2.4  Introduction of Scalable Vector Graphics Tiny (SVGT) 

2.4.1  What is SVGT? 

Because of industry demand, two mobile profiles were introduced with SVG 1.1: 

SVG 

Tiny

  (SVGT)  and 

SVG  Basic

  (SVGB).  These  are  subsets  of  the  full  SVG  standard, 

mainly intended for user agents with limited capabilities. In particular, SVG Tiny was 

defined  for highly restricted  mobile devices  such as cellphones, and SVG Basic was 

defined  for  higher  level  mobile  devices,  such  as  PDAs.  Hence,  it  was  decided  that 

SVG Tiny would  be  a strict subset of SVG Basic, itself  a strict subset of SVG  Full.

2.4.2  First impression of SVGT 

Since  SVGT  is  an  XML  format  and  follows  the  XML  grammar.  SVGT  grammar  is 

based  on  an  XML  DTD.  It  starts  and  ends  with  an 

SVG

  tag.    Objects  are  placed 

within  the  SVGT  object  to  form  graphics.  Some  basic  drawing  components  are 

provided,  such  as  rectangle,  circle,  ellipse,  line,  polyline  and  polygon;  the
