What it does How to Install Controls Versions How to Purchase Questions |  | Tesselation What it does Tesselation is a plug-in filter for paint programs. It converts color or greyscale images into seamlessly repeating tiles, suitable for graphic backgrounds for Web pages. How to install To use this software, you need a paint program which accepts standard Photoshop 3.0 plugins. Just put the plug-in filter into the folder where your paint program expects to find it. If you have Photoshop, the folder is Photoshop:Plugins:Filters or Photoshop:Plug-ins. You must restart Photoshop before it will notice the new plug-in. It will appear in the menus as Filters->Flaming Pear->Tesselation. Most other paint programs follow a similar scheme. If you have Paint Shop Pro: you have to create a new folder, put the plug-in filter into it, and then tell PSP to look there. In PSP's menus, choose File-> Preferences->General Program Preferences... and click the Plug-in Filters tab. Use a "Browse" button to choose the folder. The plugin will appear in the menus as Image->Plug-in Filters->Flaming Pear->Tesselation. Controls The big square: If you drag the little red grapple around, it changes the size of the tile. You’ll see the size of the tile in red numbers, and the size of the margins in blue. The margins are used to blend the edges of the tile so they match up smoothly. If you experiment with the control, you’ll notice that the tile can’t be narrower than the side margin, nor shorter than the bottom margin. Text boxes: Below the big square, you can type the dimensions of the tile directly. If you type a size that’s too big or too small, then the dimensions the filter will really use will appear in the the big square . Wrap top & bottom and Wrap sides: Usually you will want to make tiles that repeat vertically and horizontally, but you can do just one if you prefer. For example, you could make a wide graphic that only repeats vertically, and use it to make a stripe down the side of a Web page. Blending: This popup menu offers a linear blend for the edges of the tile as the default choice. If you find that produces a harsh, obvious-looking seam, there are two softer blending curves you can use instead. OK: Applies the effect to your image. Cancel: Dismisses the filter, and leaves the image unchanged. Register: Allows you to type in a registration code. When you click OK and apply the effect, a checkerboard margin will replace the right and bottom edges of the selection, and the remaining part is now a tile. You need to crop out the tile by hand.
