Mosaics and tessellations 721

In some cases, Corel Painter might not put a tile in every space. You can fill

openings by choosing the Apply Tiles tool and applying the tiles.

If you want to change the tiling of an area, you can use the Remove Tiles

tool to clear it. Then you can reapply tiles manually.

Adding mosaic effects to an image

You can add mosaic effects to an image that already contains brushstrokes, layers, or

objects. However, because mosaics are applied directly to the canvas, you need to

incorporate mosaic effects carefully or you could lose some of the existing content.

When you create a mosaic, the entire canvas is automatically covered with the grout

color. This obliterates images that are currently on the canvas, but leaves objects that

hover above the canvas, such as layers and shapes. These objects are not deleted, but

they do cover up the mosaic that you’re working on.

If you want to incorporate a mosaic with another image, you have several options:

• Using selections — You can add the mosaic effect to a portion of an image by

filling a selection with a mosaic effect. For information, see “Stroking and filling a

selection with mosaic tiles” on page 719.

• Using multiple documents — You can create the mosaic in its own document.

When you’re satisfied with the result, float and copy the mosaic to the document

where you want to composite it. For more information, see “Converting selections

into layers or floating objects” on page 486.

• Using layers — You cannot add a mosaic to a layer. However, you can float the

non-mosaic portion of the image using a layer. Create the mosaic on the canvas and

when you’re satisfied with the mosaic, you can drop the layers.

Creating tessellations

A tessellation is a type of mosaic that is made up of nonrectangular tiles. With

Corel Painter, you can create a tessellation from scratch or from a clone source. A

tessellation that is based on a clone source is a powerful option. The tessellation points

are distributed according to the luminance of the clone source. Lighter regions receive

a greater density of points, so the shapes are smaller.
