CHAPTER 7 FILTERS AND EFFECTS 291 Figure 7-34. Define regions in ImageMap that will take the user to different web pages. To define a rectangular or circular region, click at one corner, move to the other corner, and click again. A dialog pops up to let you enter the website for that region. Polygonal regions are only slightly more complicated. Click on each point in turn, building up the region. When you get to the last point, double-click instead of single-clicking to complete the region and bring up the dialog. You can select regions and edit or change them by clicking on them in the list on the right side of the dialog. When you ve defined all your regions, you can save the image map using the ImageMap dialog s File . Save…. The filters Py-Slice and Perlotine are two ways of chopping up an image into a table of smaller images to put on a web page. Py-Slice is written in Python and Perlotine in Perl (so in GIMP versions prior to 2.4, look for them in the menus with those names), but otherwise they re pretty similar. Drag guides from the left and top rulers in the GIMP image window to define where the image will be chopped. Either Py-Slice or Perlotine will chop the image into bits, and then generate a web page in which the bits are reassembled as a table. You can specify the type of image that will be saved (GIF, JPG, or PNG), where the HTML and new images will be written, whether there should be space between the images in the table, and a few other details about how you want the web page to work. This is useful for lots of different sorts of web pages. You can use an image of a keypad to let the user enter numbers; or you can split a map into quadrants and let the user explore them separately. Or you might just want to display extra space between pieces of your image. The GIMP won t show you the web page: it doesn t know how to show HTML! You ll have to open the HTML file in a web browser to see the result. Of course, there won t be any links on the individual images yet; you ll have to edit the page to make it do what you want.
