11.4. Optimize SVG

Geometry optimizations are achieved by :
First by using path relative commands instead of absolute commands
- the argument separator optimization option allows you to reduce the number of commas (l20,-10 becomes l20-10)
- The option of grouping successive operators allows the syntax to be further reduced (l20,10,l10.5 becomes l20,10,10,5)
Converting geometric objects to path (line,polyline,polygon)
Consolidation of transformation matrices (translate(..)scale(..) becomes matrix(..))
Reducing the number of decimal places
The size reduction can be significant.
Style optimizations group properties assigned by attributes or inline (eg stroke=".." or style="stroke:..") into CSS classes.
CSS classes are computed to factorize properties between more than one element.
The last option, moving attribute properties to inline, is more a syntax convenient than a size optimization.
Text optimizations are achieved by removing empty texts between items and also comments.
These are useful when the SVG is hand written.
