Outline Effects

Outline Effects

The Outline section of the shape effects, contains a set of parametric outline adjustment effects. These effects will adjust the outlines of the objects individually, creating new shapes from the existing object shapes.

In some of these shape effects, the primary shape effect tool can be used to adjust shape effect attributes interactively.

Detail

The Detail outline distortion effect adds or removes low level details of shapes. The low level details are adjusted by keeping high level aspects of the shape intact. The level of detail to keep or adjust can be selected by the user.

The Detail effect can also be used to copy low level detail from other shapes.

The Detail outline distortion, with basic options.

Advanced options of the Detail outline distortion.

The Detail outline effect uses the following basic options:

  • Sample - Select the sample shape used to adjust high level details of the filtered shapes. The sample shape can be selected from the list of shape presets, styles and object references with the Shape role. This option is enabled only if the Adjustment option is selected.
  • Density - Edit the density of the sampling of both the filtered shapes and the detail sample shape.
  • Level - Edit the amount of high level detail to keep from the original shape. The low level details are adjusted randomly or by the sample shape, depending on the selected options.
  • Tempering - Edit the strength of randomization of the low level shape details.
  • Seed - Set the randomization seed used to generate low level details. The button can be used to pick random seed values.
  • Adjustment - Enable or disable the adjustment of the filtered shape using low level details from the selected sample shape.
  • Randomized - Enable or disable the adjustment of the filtered shape using randomly generated low level details.

More advanced options of the Detail distortion are available, by clicking on the button.

  • Intensity - Select a function to adjust the intensity of low level detail changes. The Cubic and Monotone Cubic functions are edited by selecting the Edit Curve command.
  • Smoothness - Edit the smoothness of the reconstructed curve shapes.
  • Segment - Edit the maximum segment length. Longer segments are split into shorter parts.
  • Amount - Edit the strength of the low level details copied from the sample shape.

Displacement

The Displacement outline distortion effect moves locations of a shape using a mask image created from an other object. The amount of movement of shape positions can be controlled locally, by the color intensity of the mask object. The Displacement effect can be used for example, to create a relief of a mask in a set of outlines.

Any user created object (or group of objects) can be used as the displacement mask, by assigning a name to the object, and enabling the Filter Image role for the object with the Object Options command.

Modifying or editing the mask object will automatically update all displacement effects using the mask.

The Displacement outline distortion, with basic options.

Advanced options of the Displacement outline distortion.

The Displacement outline effect uses the following basic options:

  • Displace - Select the displacement mask object. This field opens a list of objects with the Filter Image role, from the current document. Typically these objects are placed on a reference sheet.
  • Radius - Edit the radius of the displacement mask, relative to the extend of the distorted outlines.
  • Amount - Edit the maximum amount of displacement.
  • Rotation - Edit the rotation of the displacement mask.
  • Direction - Set the direction of the displacement of outline points.
  • Smoothing - Set the amount of extra smoothing applied to the displaced outline nodes.
  • Lines - Set the maximum length of lines created when the Split Lines option is enabled.
  • Split Lines - Enable or disable the splitting of lines into multiple smaller length lines. When enabled, the displacement effect splits the lines of shapes into smaller lines (limited by the length in the Lines field). The displacement mask relief is then approximated using these lines, creating a sharp relief. When disabled, the displacement mask relief is approximated using smooth curves.
  • Proportional - Enable or disable the proportional fitting of the displacement mask to the distorted outline region.
  • Original Size - Enable or disable the the use of the original displacement mask size.

More advanced options of the Displacement distortion are available, by clicking on the button.

  • Stretch - Edit the amount of vertical stretching of the displacement mask.
  • Steps - Edit the maximum number splits made on a single curve segment.
  • Resolution - Edit the resolution of the displacement mask.
  • Center X and Center Y - Set the center of the displacement distortion.

The displacement mask can be interactively positioned, sized, rotated and stretched, using the using the primary shape effect editor tool:

  • Click on the original shape at any location and drag to set the offset distance.
  • If the distance is uniform (default width profile), hold the Command key and click at a location on the shape to add a different, non-uniform distance at that location.
  • If the distance is non-uniform, clicking at a location will add a new width node and a local offset distance.
  • The width nodes can be dragged and positioned along the shape to set the location of various offset amounts.

The button from the Shape Effects panel, activates the shape effect tool used to interactively edit the circular bump distortion attributes.

Interactive editing of the Displacement effect.

Interactive editing of the displacement distortion is done by dragging the handles to change an attribute value:

  • (1) - Set the vertical stretching of the displacement mask, by dragging this handle towards or away from the center.
  • (2) - Set the center of the displacement mask.
  • (3) - Set the radius of the displacement, by dragging this handle towards or away from the center.
  • (4) - Set the rotation of the displacement mask, by dragging this handle around the center.
  • (5) - Set the amount of displacement, by dragging this handle along the axis of the displacement rotation.

Offset Path

The Offset Path outline distortion effect offsets the object outlines outwards or inwards by a user defined amount. A variable width profile can be used to create non-uniform outline offset effects.

The Offset Path outline distortion, with basic options.

Advanced options of the Offset Path outline distortion.

The Offset Path outline effect uses the following basic options:

  • Distance - Edit the shape offsetting distance. Positive distances will offset closed shapes outwards. Negative distances will offset closed shapes inwards.
  • Precision - Edit the precision used to calculate the shape offsets. The precision value is used to select between approximating the ideal shape offset or using as few new shape nodes as possible.
  • Profile - Select the variable width profile preset or style, used in the shape offsetting. The variable width profile controls the variation of the distance of the offset shape. To set custom variable width profiles, click on the button, or use the primary shape effect editor tool.

The shape offset distance can be edited interactively, using the primary shape effect editor tool:

  • Click on the original shape at any location and drag to set the offset distance.
  • If the distance is uniform (default width profile), hold the Command key and click at a location on the shape to add a different, non-uniform distance at that location.
  • If the distance is non-uniform, clicking at a location will add a new width node and a local offset distance.
  • The width nodes can be dragged and positioned along the shape to set the location of various offset amounts.

  • The width nodes can be dragged and positioned along the shape to set the location of various thickness amounts.

Overlay

The Overlay outline effect overlays a user selected open shape along the distorted shapes. This effect is similar to the outline zigzag effect, with the difference, that any user editable open shape can be used to create a variation along the distorted shapes.

The overlay shape can be any previously saved shape style or preset, or the shape of any object having the Shape role. The overlay shape may contain closed paths, or may be a closed shape altogether. In case of closed shapes, the overlay effect will space the overlay shape along the distorted paths using the spacing set in the advanced options.

  • Mirrored - Enable or disable the mirroring of every second overlay shape.
  • Flipped - Enable or disable the flipping of mirrored overlay shapes.
