Adobe illustrator cs4- P15: Good designers have many tools at their disposal. Especially in an environmentwhere most designers have other powerful graphics applications, itcan be diffi cult to choose which one to use for a particular task. For example,a designer can apply soft drop shadows in Photoshop, Illustrator, andInDesign—is one application any better than the others for this?

Adobe illustrator cs4- P15394 CHAPTER 12: WORKING WITH IMAGES Exploring the Live Trace Preview Options Once you’ve traced an image, Illustrator displays the traced result on your artboard so you can see the results. However, Illustrator offers a variety of settings that you can use to control how both the raster image and the traced vector result appear on your artboard. When a traced image is selected on the artboard, the Control panel updates to contain two icons that, at first glance, look like triangles. Upon closer inspection, you’ll notice that one icon features a jagged edge; this icon is used to control how the raster image is previewed. The icon on the right, which has a smooth edge, is used to control how the traced vector result is previewed (Figure 12.17).Figure 12.17 Once you’ve Raster Image Preview Settingtraced an image, you canuse the two icons in theControl panel to controlhow the artwork appearson the artboard. Vector Result Preview Setting Previewing the Original Raster Image In the Control panel, the jagged triangle on the left controls how the raster image is viewed. Click the icon once, and choose from one of the following four available settings (Figure 12.18): • No Image. This setting completely hides the raster image from the screen (and is the default setting). • Original Image. This setting displays the original raster image in your document, which can be useful when you’re comparing the original image to the traced result. • Adjusted Image. This setting displays the raster image as it appears after Live Trace has applied the raster conditioning adjustments. This preview mode is great for seeing how Live Trace works, and it makes it easier to preview any adjustments you make to the raster image settings.
