Just like shapes and lines, text in SVG can be a pre-defined symbol.
The advantage of defining text as a symbol is that it is created once and can be replicated countless times in multiple locations on an SVG image. Consider the image below:
It is created from the code below:
$SVG_T:=SVG_New (400;200) $MyPat_T:=SVG_Define_pattern ($$SVG_T;"myGrid";20;20;0;0;"userSpaceOnUse") $Use_T:=SVG_New_rect ($MyPat_T;0;0;20;20;0;0;"black";"beige";0.5) SVG_SET_OPACITY ($Use_T;-1;20) $Symbol_T:=SVG_Define_symbol ($SVG_T;"RefText") SVG_New_text ($Symbol_T;"This is Referenced text";0;0\ ;"Lucida Grande,Verdana";18;Plain;Align left;"red") SVG_New_rect ($$SVG_T;0;0;400;400;0;0;"";"url(#myGrid)";1) SVG_Use ($SVG_T"RefText";20;20) SVG_Use ($SVG_T;"RefText";60;60) SVG_Use ($SVG_T"RefText";100;100) SVG_Use ($SVG_T;"RefText";140;140) |
Notice that the text is defined once using SVG_Define_symbol and then referenced or used four times with SVG_Use. This is far more efficient and managable than repeating the use of SVG_New_text.
