Envelope Distort

Overview

An Envelope Distortion is a process that allows you to use a Mesh to distort a target, a single object or set of objects that you select before you apply the Envelope Distortion. Targets can contain vector objects, text objects, embedded images, or a combination of all three, but cannot contain a linked image.  

An Envelope Distortion is a process that allows you to use a Mesh to distort a target, a single object or set of objects that you select before you apply the Envelope Distortion. Targets can contain vector objects, text objects, embedded images, or a combination of all three, but cannot contain a linked image. 

 The Mesh used in an Envelope Distort object is the same type of object that you would create with the Object > Create Gradient Mesh command or with the Mesh tool. You can actually edit an Envelope Distortion object with the Mesh tool and when you select an Envelope for editing, the Appearance panel will show that the object is a Mesh. However, when used in an Envelope, it functions differently than it does in a Gradient Mesh. The Mesh is used not just as a framework for shading or coloring its Points and Patches. Instead, when used with Envelope Distort, the topology of the Mesh controls how the Mesh will distort the Contents. The distortion always (A) fills the entire Envelope and (B) follows the paths of the Mesh. That is, a rectangular Mesh, is neutral; it does not distort the Contents, but moving any point in a rectangular Mesh will cause a corresponding distortion in the Contents.

 You can create an Envelope Distortion object in 3 ways, each of which has a corresponding command in the Object > Envelope Distort menu:

  • The Make with Warp (Alt + Shift + Ctrl + W) command allows you to select the Mesh from a number of presets. Each preset creates a corresponding distortion in the target. The presets present the same options as are available from the Effect > Warp command (Arc, Arc Lower, Arc Upper, Arch, Bulge, Shell Lower, Shell Upper, Flag, Wave, Fish, Rise, FishEye, Inflate, Squeeze, and Twist).
  • The Make with Mesh (Alt + Ctrl + M) command allows you to create an Envelope with a neutral, rectangular Mesh. To distort the Contents, you must edit this Envelope so as to change the trajectory of its Mesh lines.
  • The Make with Top Object (Alt + Ctrl + C) command allows you to use an arbitrary shape as the Mesh. You place the Mesh above the target in the Layers panel stacking order, select them both, and then execute the Make with Top Object command. By default, Ai places Mesh points only on the border of the shape, but you can add more Mesh points with the Mesh tool.

Thus, when you use the Make with Warp and Make with Mesh commands, Ai supplies the Mesh. When you use Make with Warp, Ai lets you choose the Mesh from a number of presets. When you use Make with Mesh, Ai initially supplies a simple, non-distorting rectangular Mesh. However, when you use Make with Top Object, Ai allows you to actually draw the shape that it converts into the Mesh.

Illustration of How to
With the Edit Envelope button pressed (left) you are editing the Envelope's Mesh. With the Edit Content button pressed (right) you the Layers panel shows the Envelope's Contents, which you can edit in the usual way.

The Envelope object is both a container (for its Contents, the target objects), but it is also an object with its own special (Mesh) properties that most containers do not have. Hence, while you can edit either the Envelope's Mesh or its Contents, you cannot edit both at the same time as you would with a normal container. Instead, you must first signal whether you want to edit the Envelope's Mesh or its contents. Therefore, before you can start editing, you must first Select the Envelope object and then click either the Edit Envelope button (which is on by default), or the Edit Contents button. When (and only when) you click the Edit Envelope button, will you get access to the Anchor Points and Control Handles of the Mesh. Similarly, when (and only when) you click the Edit Contents button, will you see the Envelope's row in the Layers panel display a disclosure triangle, signaling that it will now act like a container, and give you access to the contents.

With the Edit Envelope button pressed (left) you are editing the Envelope's Mesh. With the Edit Content button pressed (right) you the Layers panel shows the Envelope's Contents, which you can edit in the usual way.

  • With the Edit Envelope button pressed (left) you are editing the Envelope's Mesh. With the Edit Content button pressed (right) you the Layers panel shows the Envelope's Contents, which you can edit in the usual way. Undo the Envelope Distortion and in the Layers panel, will replace the Envelope sublayer with a Group that contains the Mesh and a Group that contains the original target objects.
  • Show both the original target objects and the Mesh on the Artboard.
Illustration of How to
When you Release an Envelope Distortion, Ai gives you back not only the original target objects, but also the Mesh that it used to create the Envelope object.

With the Object > Envelope Distort > Release command you can undo the Envelope Distortion.  This command also demonstrates that Ai is non-destructive (i.e., that it preserves both the target objects and the Mesh that was used to construct the Envelope. When you execute the Release command, Ai will: 

  • Replace the Envelope sublayer in the Layers panel with a Group that contains the Mesh and a Group that contains the original target objects.
  • Show both the original target objects and the Mesh on the Artboard.

Make an Envelope that has a Warped Mesh

Create an Envelope Distortion using Make with Warp

To make an Envelope Distortion that uses a preset type of warped Mesh in Adobe Illustrator:

  1. Select all the objects that you want to make up the target.
  2. Execute the Object > Envelope Distort > Make with Warp (Alt + Shift + Ctrl + W) command. Ai will (A) apply the default style (Arc) to the target and (B) open the Warp Options dialog, which has the same appearance and options as the dialog that is invoked by the Effect > Warp command.
  3. In the dialog, select the Style: Arc, Arc Lower, Arc Upper, Arch, Bulge, Shell Lower, Shell Upper, Flag, Wave, Fish, Rise, FishEye, Inflate, Squeeze, or Twist. Figure 5 Warp Options (not to be confused with the Envelope Options) tells Ai how to construct the Mesh when you use the Make with Warp command.
  4. Illustration of How to select Warp options.
    Warp Options (not to be confused with the Envelope Options) tells Ai how to construct the Mesh when you use the Make with Warp command.
    In the dialogue you may also set parameters for the:
    1. Horizontal or Vertical orientation.
    2. Bend: the amount that the warp will bend, expressed as a positive or negative percentage of the maximum. Options id = "Warp".
    3. Distortion in the Horizontal direction expressed as a positive or negative percentage of the maximum.
    4. Distortion in the Vertical direction expressed as a positive or negative percentage of the maximum.
  5. Click OK. Ai will:
    1. Create a hidden, internal Mesh object of the type you specified Apply the distortion to the target objects.
    2. Use the internal Mesh to create an Envelope object, which, in the Layers panel, will have the default name <Envelope>.
    3. Show the word "Envelope" in the Appearance panel and below it the link to Contents. Clicking on the Contents link will reveal that it contains a Mesh, which contains Mesh Points.
    4. Show the following in the Control panel:
      1. An Edit Envelope button, which looks like the Mesh tool.
      2. An Edit Contents button, which looks like a warped star.
      3. Controls for all the options that were displayed in the Warp Options dialog.
    5. Show the Mesh's Anchor Points, and Segments on the Artboard. Ai does this because the Edit Envelope button is enabled by default. If the Edit Contents had been the default, you would see a Selection box for the Contents.

Edit Envelope

To edit the Mesh of a Warp Envelope Distortion in Adobe Illustrator:

  1. Select the Envelope.
  2. To change the Warp Options, in the Control panel, ensure that the Edit Envelope button is active; then use any of the controls for the Warp Options.
  3. To edit the Mesh Control Points directly, do any of the following:
    1. To add an Anchor Point, click on the Mesh.
    2. To delete an Anchor Point, Direct Select it and press the Delete-key.
    3. To move an Anchor Point or a Control Handle, Direct Select it and drag.

Reset with Warp

To reset the Warp Options dialog settings in Adobe Illustrator:

  1. Select the Envelope object on the Artboard or in the Layers panel.
  2. Ensure that the Edit Envelope button is active.
  3. Execute the Object > Envelope Distort > Make with Warp (Alt + Shift + Ctrl + W) command. Ai will display the Warp Options dialog with its current settings.
  4. Reset the settings.
  5. Click OK

Note:

You can also apply the Object > Envelope Distort > Reset with Warp (Alt + Shift + Ctrl + W) command to an Envelope that you created with one of the other two Envelope Distortion commands. If you do, Ai will display the Warp Options dialog, and you can essentially convert the other object into a Warp-type Envelope Distortion.

Release

To undo an Envelope Distortion in Adobe Illustrator:

  1. Select the Envelope object either on the Artboard or in the Layers panel.
  2. Execute the Object > Envelope Distort > Release command. Ai will:
  3. Undo the Envelope Distortion.
  4. In the Layers panel, replace the Envelope object, with two objects: (A) a Mesh object and (B) a sublayer for each of the original target objects.
  5. Display on the Artboard:
    1.  The original target objects as they were when the Envelope Distort command was first applied (without any of the edits that you applied when they were within the Envelope object).
    2. The Mesh object as it was just before you Released the Envelope Distortion.

Edit Contents

To edit the Contents of a Warp Envelope Distortion in Adobe Illustrator:

  1. Select the Envelope object on the Artboard or in the Layers panel.
  2. In the Control panel, click the Edit Contents button. In the Layers panel, the Envelope layer will then behave, not like a single Mesh object, but like a container, similar to a Group. Ai will display a disclosure triangle that allows you to see all the sublayers that represent the Envelope's contents, with all content sublayers selected by default. You can now:
    1. Select the entire container object and change its Attributes in the Appearance panel or give it an Effect.
    2. Click the disclosure triangle to display the Sublayers and target individual sublayers for editing.
    3. Go to the Artboard and double-click the Envelope to enter Isolation Mode and use it to select and edit the Contents.

Make an Envelope Distortion that has a Generic Rectangular Mesh

Create an Envelope Distortion Using Make with Mesh

To make an Envelope Distortion that uses that, by default, uses a generic non-distorting rectangular Mesh in Adobe Illustrator:

  1. Select all the objects that you want to make up the target.
  2. Execute the Object > Envelope Distort > Make with Mesh (Alt + Ctrl + M) command.  Ai will display the Envelope Mesh dialog.
  3. In the Dialog, set the number of rows and columns that you want the Mesh to have.
  4. Click OK. Ai will:
    1. Illustration of Envelope Mesh dialog
      The Envelope Mesh dialog tells Ai how many rows and columns you want the Mesh to have when you use the Make with Warp command. This dialog corresponds to the Warp Options dialog (not to the Envelope Options dialog).
      Create an internal non-distorting rectangular Mesh object that has the number of rows and columns that you specified in the Mesh dialog.
    2. Use the internal Mesh to create an Envelope object, which, in the Layers panel, will have the default name <Envelope>.
    3. Show the word "Envelope" in the Appearance panel and below it the link to Contents. Clicking on the Contents link will reveal that it contains a Mesh, which contains Mesh Points.
    4. Show the following in the Control panel:
      1. An Edit Envelope button, which looks like the Mesh tool.
      2. An Edit Contents button, which looks like a warped star.
      3. Controls for the number of Rows and Columns, and a Reset Envelop Shape control that will immediately reset any Mesh Points and Control Handles that you have edited so that they define a simple, non-distorting rectangular grid.
    5. Show the Mesh's Anchor Points, and Segments on the Artboard. Ai does this because the Edit Envelope button is enabled by default. If instead the Edit Contents had been the default, you would see Selection indicators around the Content objects.

Edit Envelope

To edit the Envelope in Adobe Illustrator:

  1. Select the Envelope object on the Artboard or in the Layers panel.
  2. To change the number of rows and columns in the grid, go to the Control panel, and update the Rows and or Columns controls.

To edit the Contents of a Mesh Envelope Distortion in Adobe Illustrator:

  1. Select the Envelope object on the Artboard or in the Layers panel.
  2. In the Control panel, click the Edit Contents button. In the Layers panel, the Envelope layer will then behave, not like a single Mesh object, but like a container, similar to a Group. Ai will display a disclosure triangle that allows you to see all the sublayers that represent the Envelope's contents, with all content sublayers selected by default. You can now:
    1. Select the entire container object and change its Attributes in the Appearance panel or give it an Effect.
    2. Click the disclosure triangle to display the Sublayers and target individual sublayers for editing.
    3. Go to the Artboard and double-click the Envelope to enter Isolation Mode and use it to select and edit the Contents.

Make an Envelope that uses a Closed Path as the Mesh

Illustration of How to
Three closed paths used to create the Meshes for Envelope Distortions with the Make with Top Object command. Note that on the Artboard: (A) the closed path (i.e., the Top Object) need not overlap the target, (B) the Envelope will replace the Top Object, and (C) the target will expand or contract to fill the Top Object.

Create an Envelope Distortion with Make with Top Object

To make an Envelope Distortion that allows you to create an arbitrary shape and use it as the Mesh in Adobe Illustrator:

  1. Select all the objects that you want to make up the Target.
  2. Draw a closed Path that you want Ai to use as the Mesh.
  3. Make sure that the Path is on top of the Target in the Layers panel stacking order.
  4. Execute the Object > Envelope Distort > Make with Top Object (Alt + Ctrl + C) command.  
  5. Ai will immediately:
    1. Use the Path as the Mesh and the Target as the contents to create an Envelope object, which, in the Layers panel, will have the default name <Envelope>.
    2. Show the word "Envelope" in the Appearance panel and below it the link to Contents. Clicking on the Contents link will reveal that it contains a Mesh, which contains Mesh Points. When making an Envelope Distortion with the Make with Top Object command, by default, Ai will place the Mesh points only on the outer boundary of the Distorting Path. You can, however, add more Mesh points with the Mesh tool.
    3. Show the following in the Control panel:
      1. An Edit Envelope button, which looks like the Mesh tool.
      2. An Edit Contents button, which looks like a warped star.
    4. Show the Mesh's Anchor Points, and Segments on the Artboard. Ai does this because the Edit Envelope button is enabled by default. If instead the Edit Contents had been the default, you would see Selection indicators around the Content objects.

Edit Envelope

To edit the Envelope that was made from a "Top Object" in Adobe Illustrator:

  1. Select the Envelope.
  2. To update the Envelope options for this type of Envelope Distortion object, go to the Control panel and click the Envelope Options button, which is just to the right of the Edit Contents button. Ai will pop up the Envelope Options dialog.
  3. To edit the Mesh Control Points directly, do any of the following:
    1. To add a Mesh Point, Get the Mesh tool and click on the Mesh. Ai will add a Mesh Point, which when it intersects with the boundary will add four more anchor points to the border.
    2. To delete an Anchor Point, Direct Select it and press the Delete-key.
    3. To move an Anchor Point or a Control Handle, Direct Select it and drag.

Release

To undo an Envelope Distortion in Adobe Illustrator:

  1. Select the Envelope object either on the Artboard or in the Layers panel.
  2. Execute the Object > Envelope Distort > Release command. Ai will:
  3. Undo the Envelope Distortion.
  4. In the Layers panel, replace the Envelope object, with two objects: (A) a Mesh object and (B) a sublayer for each of the original target objects.
  5. Display on the Artboard:
    1.  The original target objects as they were when the Envelope Distort command was first applied (without any of the edits that you applied when they were within the Envelope object.
    2. The Mesh object as it was just before you Released the Envelope Distortion.

Edit Contents

To Edit the Contents of a "Top Object" Envelope Distortionin Adobe Illustrator:

  1. Select the Envelope object on the Artboard or in the Layers panel.
  2. In the Control panel, click the Edit Contents button. In the Layers panel, the Envelope layer will then behave, not like a single Mesh object, but like a container, similar to a Group. Ai will display a disclosure triangle that allows you to see all the sublayers that represent the Envelope's contents, with all content sublayers selected by default. You can now:
    1. Select the entire container object and change its Attributes in the Appearance panel or give it an Effect.
    2. Click the disclosure triangle to display the Sublayers and target individual sublayers for editing.
    3. Go to the Artboard and double-click the Envelope to enter Isolation Mode and use it to select and edit the Contents.

Envelope Options

Screenshot of the Envelope Options Dialog
Envelope Options Dialog

The Envelope Options control how the Mesh will distort the target when you execute one of the Make commands.

Update Envelope Options

To apply options to an Envelope object in Adobe Illustrator:

  1. Select the object.
  2. Execute the Object > Envelope Distort > Envelop Options command or click the Envelope Options button (Envelope Options button) in the Control panel. Ai will display the Envelope Options dialog.
  3. In the dialog, update any of the following settings.

Envelope Option Settings

Anti Alias
Enabling this option can smooth jagged edges (aliasing) in raster images, which may appear when distortion exposes square pixels. It works by blending colors around edges to make the pixels less visible. Therefore, enabling Anti-Aliasing may reduce performance, and disabling it can decrease the time it takes to distort an image.
Preserve Shape Using
This area of the dialog contains a radio button group that allows you to specify that Ai should use either a Clipping Mask or Transparency (an Alpha Channel) to preserve the shape of a Mesh that is not rectangular.
Fidelity
This option tells Ai how closely it should align the target objects to the boundary of the Mesh when it constructs the Envelope.
Distort Appearance
Tells Ai that when creating the Envelope Distortion it should also distort any effects that were used in the target. This option also enables the following two options.
Distort Linear Gradients
Tells Ai that when creating the Envelope Distortion it should also distort any Linear Gradients that are used in the target.
Distort Pattern Fills
Tells Ai that when creating the Envelope Distortion it should also distort any Pattern Fills that are used in the target.
