<a name="1005219"> </a>Each mosaic tile you create is stored as a resolution-independent object within the Corel Painter image database. This means that if you resize an image composed of mosaic tiles, your image can be displayed at the same quality as if it was originally created at higher resolution.

<a name="1005223"> </a>The image that you see displayed is the set of all mosaic tiles rendered as an image onto the canvas. Mosaics can be re-rendered at any time. Once you exit the Make Mosaic dialog box, you can treat this rendered image just like any photograph or painting. You can paint it, apply effects to it, select portions of it, or increase the canvas size. However, once you choose Re-render Mosaic, Corel Painter erases any imagery that is not a tile or grout.

<a name="1008578"> </a>The first thing the Mosaic feature does is cover the entire canvas with grout. This obliterates images that are 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 you're working on.
<a name="1005240"> </a>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.

<a name="1005245"> </a>If a mosaic already exists in the document when you open the Make Mosaic dialog box, Corel Painter assumes you want to keep existing tiles and does not apply new grout. To avoid this, you can use a layer to create a mosaic on top of an image.

<a name="1005259"> </a>Fitting Tiles Together
</h3>
<p id="1005260" class="Body">
<a name="1005260"> </a>When working with real ceramic tiles, it is physically impossible to merge tiles. You can put them close to each other, but you can't make them occupy the same space. Likewise, the mosaic tiles in Corel Painter respect each other's space. Tiles don't overlap or merge. Corel Painter adjusts the shape of the tiles to fit them together while maintaining the grout lines. So, when you want to re-lay the tiles in an area, you must remove the existing tiles.
