All diagrams are now supporting this syntax.
Note that ascending compatibility with HTML syntax is preserved.

  • <s> or <s:#AAAAAA> or <s:colorName> for strike text
  • <w> or <w:#AAAAAA> or <w:colorName> for wave underline text
  • <color:#AAAAAA> or <color:colorName>
  • <back:#AAAAAA> or <back:colorName> for background color
  • <size:nn> to change font size
  • <img:file> : the file must be accessible by the filesystem
  • <img:http://url> : the URL must be available from the Internet
