You can use any image or selection to define a pattern. An image designed for use as part of a pattern

is normally created so that it tiles seamlessly. That is, the eye should not be able to distinguish the edges

between tile repetitions. Corel Painter has features that can help you create seamless tiles, which you can

then use as interesting web backgrounds. For information about creating, editing, saving, and filling with

patterns, see “Patterns” on page 709.

The Glass Distortion effect, the Super Soften effect (with the Wrap Around check box enabled), and

most of the Tonal Control effects preserve the seamless quality of the pattern. Some effects, such as Apply

Surface Texture, can result in a noticeable seam, so experiment.

Example of using seamless and non-seamless tiles in a pattern

A way to partially avoid seams that occur with effects such as Apply Surface Texture is to apply the effect

several times at lower strengths (by moving the Amount slider). Shift the pattern a little (using Shift +

Spacebar) between applications. This tends to “distribute” the seams and make them less noticeable.

Tile dimensions should be as small as practical, but in most cases should not go below 20 x 20 pixels. If a

tile is too small, it takes the browser longer to render it over a large area.

When you’ve finished creating your tile, save the image in RIFF format, in case you must work with it later in

Corel Painter. Then, save it in either JPEG or GIF format for use on the web.

Web backgrounds should, ideally, be saved as GIFs, with as few colors as possible, to reduce file size. You

can also use JPEGs, but they often have larger file sizes. As a rule of thumb, any background tile over 20 KB

is probably too large. For more information about saving an image in GIF or JPEG format, see “Saving and

backing up files” on page 88.

Creating tiles with fractal patterns

Another easy way to design seamless tiles is to take advantage of the effects you can create with the Make

Fractal Pattern command. Make Fractal Pattern is a pattern generator that creates organic patterns, which

can make interesting background tiles. The patterns it generates can be filled with color and even enhanced

with a paper texture. For more information, see “Creating fractal patterns” on page 719.

Color Overlay, the Watercolor brushes, and Cloning are other options you can apply to a pattern.

Beautiful, complex effects can also be achieved by applying Glass Distortion to a pattern created with

Make Fractal Pattern.
