Maybe it needs to be a little bigger smaller taller or wider or maybe it s perfect but it s facing the wrong way and it s upside down. Whatever the problem Fireworks has the tools to fix it and because Fireworks blends pixel surfaces with vector skeletons you get amazingly sharp results. Fireworks has the kinds of tools you would normally expect to find in a full-fledged vector drawing application. You can combine several vector objects in any number of ways with evocatively named tools such as Union Intersect Punch and Crop. Naturally what you have joined together you can split apart and regroup as needed. Vector objects can be simplified expanded or inset with Fireworks commands. This chapter covers all the tools and techniques in Fireworks for transforming and combining objects. You ll also find a section that describes how you can use Fireworks to create perspectives in your imagery. You really begin to appreciate the power of Fireworks vector bitmap combination when you start transforming your objects. In a pure bitmap graphics application if you increase the size of a bitmap you have to add pixels whereas shrinking a bitmap causes the program to throw away pixels you rarely achieve ideal results in either situation. However in Fireworks when you rescale a vector object the vector path is altered a snap for vector graphics and the pixels are reapplied to the new path just as if you had drawn it that way to begin with. In This Chapter Transforming vectors Fireworks technique creating perspective Working at the point level on a vector path Editing existing vectors Using vector power tools 268 Part II Mastering the Tools Transforming Objects Visually Fireworks includes methods for transforming objects both visually and numerically. The visual method relies on three key tools found in the Select .
