This is some SVG drawn text

Basic usage

The Text tool needs a center position, and - of course - some text to display.

    cx: 50                  # cx=50 is center position
    cy: 50                  # cy=50 is center position

- type: 'text'              # tooltype is 'text'
  position:                 # Position on (100x100) canvas
    cx: 50                  # cx=50 is center position
    cy: 50                  # cy=50 is center position
  entity_index: 0           # connect to state of entity 0
  text: 'My Text'
  styles:
    text:
      font-size: 12em       # set font size to 12em

Always use a relative font-size: it fits well with the relative sizes used by SAK

Unless you need a fixed size in pixels...

Method Support Description
classes Using SAK or User defined class definitions
