Introduction to Vector Graphics

MVG ignores all white-space between commands. This allows multiple MVG commands per line. It is common convention to terminate each MVG command with a new line to make MVG easier to edit and read. This syntax description uses indentation in MVG sequences to aid with understanding. Indentation is supported but is not required.

Metafile wrapper syntax (to support stand-alone MVG files) ---------------------------------------------------------- 
  push graphic-context
   viewbox 0 0 width height
    [ any other MVG commands ]
  pop graphic-context
Pattern syntax (saving and restoring context) --------------------------------------------- 
  push pattern id x,y width,height
   push graphic-context
    [ drawing commands ]
   pop graphic-context
  pop pattern
an example is (%s is a identifier string) 
  push defs
   push pattern %s 10,10 20,20
    push graphic-context
     fill red
     rectangle 5,5 15,15
    pop graphic-context
    push graphic-context
     fill green
     rectangle 10,10 20,20
    pop graphic-context
   pop pattern
  pop defs
For image tiling use 
  push pattern id x,y width,height
   image Copy ...
  pop pattern
Note you can use the pattern for either the fill or stroke like 
  stroke url(#%s)
or 
  fill url(#%s)
Clip-path syntax ---------------- The clip path defines a clipping area, where only the contained area will be drawn upon. Areas outside of the clipping area are masked. 
  push defs
   push clip-path %s
    push graphic-context
     rectangle 10,10 20,20
    pop graphic-context
   pop clip-path
  pop defs
  clip-path url(#%s)
