ADOBE ILLUSTRATOR CS3 Chapter 4 Transforming and Distorting Objects
Transform objects Defining the Transform Tools Transformation occurs when an object s size, shape, or position is changed on artboard Tools panel contains five transform tools: Rotate Scale Reflect Shear Free Transform Chapter 4 2
Transform objects Defining the point of origin All transformations executed in relation to a fixed point and called point of origin Default point of origin is object s center point You can change center point to another point on the object or somewhere else on the artboard Chapter 4 3
Transform objects Defining the point of origin There are four basic methods for making transformations with transform tools Click a transform tool, then click and drag anywhere on artboard Double-click transform tool, which opens tool s dialog box Click a transform tool, then click artboard to define point of origin Click transform tool, press [Alt](Win) or [option](mac), then click artboard and tool's dialog box opens Chapter 4 4
Transform objects The Reflect Tool flips an image All transformations are executed from a point of origin Chapter 4 5
Transform objects Working with the Transform Again Command You can repeat a transformation again quickly with the Transform Again command Scale or rotate Moving Quickest way to use Transform Again command is to press [Ctrl][D](Win) or Ë [D](Mac) Chapter 4 6
Transform objects Using the Transform Each command Command allows you to transform multiple objects individually Transform Each dialog box offers options to move, scale, rotation, or reflect an object among others Before After The eight squares are rotated on their own center points Chapter 4 7
Transform objects Using the Free Transform Tool The Free Transform Tool applies an eight-handled bounding box to a selected image Move handles to scale and shear object Click and drag outside the object to rotate the object Moving handles in conjunction with keyboard commands allows you to distort the object, or distort object in perspective Press and hold [Shift][Ctrl](Win) or [Shift]Ë (Mac) to distort image Press and hold [Shift][Alt][Ctrl](Win) or [Shift][option]Ë (Mac) while dragging to distort in perspective Chapter 4 8
Transform Objects Using the Transform panel Transform panel displays information about size, orientation, and location of one or more selected objects Type new values directly into the Transform panel to modify selected objects You can identify the reference point on the bounding box from which the object will be transformed Chapter 4 9
Transform Objects Use the Free Transform Tool to distort objects in perspective Chapter 4 10
Transform Objects Transform panel list arrow Rotate text box Height text box Width text box Shear text box Chapter 4 11
Offset and Outline Path Command Using the Offset Path command Offset Path command creates a copy of a selected path set off by a specific distance Useful when working with closed paths making concentric shapes or making many copies of a path at a regular distance from original When you offset a closed path Positive value creates larger copy outside original Negative value creates a smaller copy inside original Chapter 4 12
Offset and Outline Path Command Concentric circles produced by the Scale Tool Concentric circles produced by the Offset Path command Chapter 4 13
Offset and Outline Path Command Using the Outline Stroke command Outline Stroke command converts a stroke path into a closed path the same width as original stroke path Useful for applying gradient to a stroke Useful design tool for modifying object outline Easier to create an object with a single heavy stroke then convert it to a closed path Chapter 4 14
Offset and Outline Path Command The Outline Stroke command converts a stroked path to a closed object Chapter 4 15
Create Compound Paths Defining a compound path Compound path used to make hole or holes in an object Select the object in back and the object in front and apply the Make Compound Path command If you move the front object independently, it yields interesting results which Illustrator calls compound shapes Chapter 4 16
Create Compound Paths Defining a compound path When two or more objects are compounded, Illustrator defines them as one object Compound paths function as groups Select and manipulate an individual element with Direct Selection Tool Cannot change appearance attributes independently Chapter 4 17
Create Compound Paths Releasing a compound path Apply the Release Compound Path command to return objects to original composition Chapter 4 18
Create Compound Paths The letter D is an example of a compound path Chapter 4 19
Create Compound Paths Manipulating compound paths can yield interesting effects Chapter 4 20
Work with the Pathfinder Panel Defining a compound shape A compound shape is two or more paths combined so that holes appear Chapter 4 21
Work with the Pathfinder Panel Understanding essential pathfinder filters Pathfinders are preset operations that help combine paths Useful for creating complex or irregular shapes from basic shapes Illustrator offers ten pathfinders five are essential Chapter 4 22
Work with the Pathfinder Panel No Filter Add Subtract Intersect Minus Back Divide Chapter 4 23
Work with the Pathfinder Panel Using the Pathfinder panel Create compound shapes by overlapping two or more objects, then clicking one of four shape mode buttons Add Subtract Intersect Exclude When shape mode button applied, two overlapping objects combined into one object with same formatting as top level Chapter 4 24
Work with the Pathfinder Panel Using the Pathfinder panel After shape mode button applied, original objects can be selected and formatted using Direct Selection Tool Another way is to click Expand button in Pathfinder panel Another is to press[alt](win) or [option](mac) Chapter 4 25
Work with the Pathfinder Panel Add to shape area button Subtract from shape area button Intersect shape areas button Exclude overlapping shape areas button Divide button Minus Back button Trim button Merge button Crop button Outline button Chapter 4 26
Work with the Pathfinder Panel Applying shape modes and pathfinders When shape modes are applied to objects, compound shape can be manipulated endlessly When shapes are expanded, the result is final Chapter 4 27
Creating Clipping Masks Defining a Clipping Mask Use clipping mask as a window to see some or all of the objects behind the mask in the stacking order Apply Make Clipping Mask command Top object becomes the mask Objects behind become masked Only parts of masked object seen will be through mask Chapter 4 28
Creating Clipping Masks Four objects being masked Black circle becomes mask Chapter 4 29
Creating Clipping Masks Using multiple objects as a clipping mask First, make them into compound paths Illustrator regards compound paths as a single object Single object can be used as a single mask Creating mask effects Position as many items as you want behind mask Chapter 4 30
Creating Clipping Masks Masks can be used for stunning visual effects Chapter 4 31
