Variables, or Data-driven graphics make it possible to produce multiple versions of an image quickly and accurately. Let’s say, for example, that you need to produce 500 different Web banners or 200 different business cards based on the same template. In the past, you had to manually populate the template with data (images, text, and so on). With data-driven graphics, you can use a script referencing a database to generate the Web banners for you. In Photoshop CS3 you can automate this process with the Variables feature. Basically, you design a template in Photoshop, putting all of the elements that will change (the variable elements) on separate layers, and then select layers in the template and assign them as variables. You can assign three different types of variables: • Visibility variables let you show or hide the content of a layer. • Pixel Replacement variables let you replace the pixels in the layer with pixels from another image file. • Text Replacement variables let you replace a string of text in a type layer. To define a variable in Photoshop, target the layer and select Image > Variables > Define. In the Variables dialog box, choose the desired layer, select the variable type and enter names for the variables. Note: Variable names must begin with a letter, underscore, or colon and cannot contain spaces or special characters (except for periods, hyphens, underscores, and colons). For Pixel Replacement variables, click Pixel Replacement Options, and choose a method for scaling the replacement image. If you are replacing pixels (photos for example) make sure that the images are in the same folder as the template. To define variables for an additional layer, choose a layer from the Layer pop-up menu and repeat the steps above.
