2 BITMAP IMAGES VS VECTOR GRAPHICS WORKING WITH BITMAP IMAGES AND VECTOR GRAPHICS Computer graphics fall into two main categories--bitmap and vector. You can work with both types of graphics in Photoshop and ImageReady; moreover, a Photoshop file can contain both bitmap and vector data. Understanding the difference between the two categories helps as you create, edit, and import artwork. VECTOR GRAPHICS Vector graphics are made up of mathematically defined lines and curves called vectors. This means that you can move, resize, or change the color of a line without losing the quality of the graphic. Vector graphics are resolution-independent-- that is, they can be scaled to any size and printed at any resolution without losing detail or clarity. As a result, vector graphics are the best choice for representing bold graphics that must retain crisp lines when scaled to various sizes (logos, for example).

Also, if direction lines appear, you've accidentally dragged the Pen tool; choose Edit > Undo and click again.

Dragging to extend direction lines Drawing the second point in a curve A. Starting to drag second smooth point B. Dragging away from previous direction line, creating a "C" curve C. Result after releasing mouse button Drawing an S curve A. Starting to drag new smooth point B. Dragging in same direction as previous direction line, creating an "S" curve C. Result after releasing mouse button

Dragging to complete the curve Drawing a curved segment followed by a straight segment (part 2) C. Positioning Pen tool over existing endpoint D. Clicking endpoint E. Clicking next corner point

19 Selection + selection and direct selection tool Selection Selection Direct selection The Selection tool lets you select objects and groups by clicking any spot on them (or within them if the object or group is filled) or by dragging over them. Direct selection Direct selection The Direct Selection tool lets you select individual anchor points or path segments by clicking on them, or select an entire object or group by selecting any other spot on the item. You can also select one or more objects in a group of objects

20 Selection + Lasso and Magic Wand Selected Area The Lasso tool lets you select objects, anchor points, or path segments by dragging around all or part of the object. The Magic Wand tool lets you select objects of the same color, stroke weight, stroke color, opacity, or blending mode by clicking the object.

21 Paintbrush Tool The Paintbrush tool lets you draw a path and apply a brush stroke simultaneously. Illustrator sets down anchor points as you draw; you do not determine where the anchor points are positioned. However, you can adjust them once the path is complete.

22 Pencil Tool The Pencil tool lets you draw open and closed paths as if you were drawing with a pencil on paper. It is most useful for fast sketching or creating a hand-drawn look. Once you draw a path, you can immediately change it if needed. Using the Smooth tool A. Original path B. Dragging across path with the Smooth tool C. Result

23 Type tool Area Type Tool Vertical Type Vertical Type on Path Type Tool Type on Path Vert.Area Type Point type is a horizontal or vertical line of type that begins where you click on the artboard and expands as you enter characters. Entering type this way is useful for adding a few words to your artwork. Area type uses the boundaries of an object to control the flow of characters. When the type reaches a boundary, it automatically wraps to fit inside the defined area. Entering type this way is useful when you want to create one or more paragraphs of text, such as for a brochure. Type on a path flows along the edge of an open or a closed path. The path can be regularly or irregularly shaped. Entering horizontal type on a path results in characters that are parallel to the baseline. Entering vertical type on a path results in characters that are perpendicular to the baseline.

26 Type tool Original Wrap Object Invert Wrap Object Important: If the layer contains multiple type objects, move any that you don't want to wrap around the wrap object either into another layer or above the wrap object.

27 Create outline The Create Outlines command (and the same command as an effect--outline Object) lets you turn type into a set of compound paths that you can edit and manipulate as you would any other graphic object. Create Outlines and Outline Object are useful for changing the look of large display type, but they are rarely useful for body text or other type at small sizes. These commands get font outline information from the actual font files installed on your system. When you create outlines from type, characters are converted in their current positions; they retain all graphics formatting such as their stroke and fill. Original Create Outline When you convert type to outlines, the type loses its hints--instructions built into outline fonts to adjust their shape so that your system displays or prints them optimally at a wide range of sizes. Therefore, if you plan to scale the type, do so by adjusting its point size before converting it to outlines. You must convert all the type in a selection to outlines; you cannot convert a single letter within a string of type. To convert a single letter into an outline, create a separate piece of type containing only that letter. 12 Modify object Note: You can't convert bitmap fonts or outline-protected fonts to outlines.
