    description: >
      Render rich text from a string containing a subset of HTML 4.
      The only other properties that can be used with this are geometry and
      bgcolour. The geometry width and height defines the page or block size
      while its X and Y coordinates determine its position.
      This property has a higher priority than argument; argument is ignored if
      this property is set.
    mutable: yes

      Render rich text from a file containing a subset of HTML 4.
      The only other properties that can be used with this are geometry and
      bgcolour. The geometry width and height defines the page or block size
      while its X and Y coordinates determine its position.
      This property has a higher priority than both argument and html; argument
      and html are ignored if this property is set.

    title: Hide
    type: boolean
    description: >
      Setting this property will not be serialized (unlike "disable"). When set
      true (1), the filter does not render. This allows an authoring tool to
      provide its own rendering while editing and then let the filter render
      outside the tool UI.

  - identifier: overflow-y
    title: Vertical Overflow
    type: boolean
    description: >
      This option applies only when using html or resource properties. It
      controls whether the text will be cropped to the geometry property or
      allowed to overflow. When not set, it is automatic based on whether the
      geometry height is greater than or equal to the profile height. The
      default is unset/automatic.
    mutable: yes

  - identifier: pixel_ratio
    title: Pixel Ratio
    type: float
    description: >
      This option applies only when using html or resource properties. It adds
      a scaling factor to the rendering. This can be used to help to make MLT's
      output match a user interface.
      NOTE: this property is only used on Windows because it is the only platform
      found thus far that has different rendering behavior relative to device
      pixel ratio.
    minimum: 1.0
    default: 1.0
