Chapter 7
Working with Distortions, Gradient Meshes, Envelopes, and Blends
Objectives
• Edit colors and distort objects
• Work with gradient meshes
• Work with envelopes
• Create blends

Edit Colors and Distort Objects
• Illustrator provides a number of effects that you can use to alter the shape of an object.
• The Pucker & Bloat effect adjusts the segments between an object’s anchor points.

Before Pucker effect
After Pucker effect; segments appear curvedinward
Original shape of object is evident by bounding box
Edit Colors and Distort Objects
• The Bloat effect is achieved by moving the segments outward and the anchor points inward.

After Bloat effect—segments are moved outward
Edit Colors and Distort Objects
• The Twist effect rotates an object more sharply in the center than it does at the edges, creating a whirlpool effect.

After Twist effect; center is rotatedmore than edges
Edit Colors and Distort Objects
• The Edit Colors commands on the Edit menu are very useful for quickly applying color changes to objects.
• The changes are applied directly to the objects; they are not effects.

Edit Colors and Distort Objects
• You can saturate colors or desaturate colors in an illustration.
• You can also use the Convert to Grayscale and Blend Front to Back commands.

Saturate filter intensifies color
Convert to Grayscale filter removes all chromatic color
Work with Gradient Meshes
• The Mesh tool and the Create Gradient Mesh command can be used to transform a basic object into a mesh object.
• A mesh object is a single, multicolored object in which colors can flow in different directions, and colors transition gradually from point to point.

Work with Gradient Meshes
• When you create mesh objects, multiple mesh lines crisscross the object.
• Mesh points are diamond-shaped and work like anchor points.– Can be assigned a color– When assigned, color flows outward from
point

• Area between four mesh points is a mesh patch.
• Apply color to all four mesh points simultaneously by applying color to patch.

Work with Gradient Meshes
• You can apply opacity settings to a mesh point on a gradient mesh.
• Select one or more points on the mesh, then drag the slider in the Transparency panel.

Work with Gradient Meshes
• Mesh points can be added, deleted, and moved along mesh line without altering mesh shape.
• Manipulate anchor points’ direction lines to alter shape of mesh.

• The shape of the mesh is manipulated by direction lines.
• Mesh points can be moved, just like anchor points.
Work with Gradient Meshes
• You can create a mesh object from any path.
• You cannot create a mesh from compound paths or text objects.
• Use the Mesh tool or apply the Create Gradient Mesh command.

Work with Gradient Meshes
• The Create Gradient Mesh command creates a mesh object with regularly spaced mesh lines and mesh points.

Work with Gradient Meshes
• Once you create a mesh object it can’t be converted back.
• Complex mesh objects are a memory drain and may effect computer performance.– Better to create a few simple mesh objects
rather then a single complex one

Three interior mesh points darkened
Work with Envelopes
• Envelopes are objects used to distort selected objects.
• Objects take on shape of envelope object.
© 2011 Delmar Cengage Learning
Work with Envelopes
• Make envelopes with: • Objects you create• Preset wrap shapes • Mesh objects
• Use envelopes with compound paths, text objects, meshes, and blends.

Resulting envelope effect
Work with Envelopes
• Create envelopes with top objects, meshes, and wraps.
• Create an envelope by using the Envelope Distort command on the Object menu.
© 2011 Delmar Cengage Learning
Work with Envelopes
• Make with Warp – 15 premade shapes
• Make with Mesh – same as gradient. meshes made with Mesh Tool.
• Make with Top Object – top most selected object.
© 2011 Delmar Cengage Learning
Work with Envelopes
• Envelopes can distort objects with linear gradient fills or pattern fills.
• Click the Distort Linear Gradients or Distort Pattern Fills in Envelope Options dialog box to activate.

Create Blends
• A blend is a series of intermediate objects and colors between two or more selected objects.
© 2011 Delmar Cengage Learning
Create Blends
• Blends are created with:– Blending tool or– Make Blend command
© 2011 Delmar Cengage Learning
Create Blends
• Make blends between:– two open paths– two closed paths– objects filled with gradients– blends
© 2011 Delmar Cengage Learning
Create Blends
• The fewer the number of steps in a blend, the more distinct each object will be.
• A large number of steps creates the illusion of being continuous or “smooth.”
© 2011 Delmar Cengage Learning
Create Blends
• In Blend Options dialog box select– Specified Steps– Specified Distance– Smooth Color – default option
© 2011 Delmar Cengage Learning
Create Blends
• You can create a simple blend between open paths.
• You can create color effects with a blend and a mask.

Chrome letters created with a blend and a mask
Create Blends
• Affect the appearance of a blend by manipulating its spine.
• When blend created, path is drawn between starting and ending objects – referred to as spine and manipulated like a path.
© 2011 Delmar Cengage Learning
Create Blends
• Examples:– Add anchor points to spine with Pen tool, then
move them with Direct Selection tool– Spine can be replaced by drawing a path with
Pen tool, then select it along with any blend and apply the Replace Spine command
