314 CHAPTER 20 IMAGE EDITING Artistic: These (Web server version)
314 CHAPTER 20 IMAGE EDITING Artistic: These filters allow you to add painterly effects to the image, such as making it appear as if the photo has been painted in impressionistic brushstrokes, or as if it were painted on canvas by overlaying the texture of canvas onto the picture. Figure 20-9 shows an example of applying a filter for an oil painting effect. Figure 20-9. The Artistic effects can be used to give images an oil painting effect. Map: These filters aim to manipulate the image by treating it like a piece of paper that can be folded in various ways and also stuck onto 3D shapes (a process referred to as mapping). Because the image is treated as if it were a piece of paper, it can also be copied, and the copies placed on top of each other to create various effects. Render: Here, you ll find filters designed to create new images from scratch, such as clouds or flame effects. They obliterate anything that was previously underneath on that particular layer or within that selection, and the original image has no bearing on what is generated by the filter. Web: Here, you can create an image map for use in a web page. An image map is a single image broken up into separate hyperlinked areas, typically used on a web page as a sophisticated menu. For example, an image map is frequently used for a geographical map on which you can click to get more information about different regions.
