Corel Painter 357
Using Layers
You can float the non-mosaic portion
of the image. Create the mosaic on the
canvas. When you’re satisfied with the
mosaic, you can drop the layers.
Layering Mosaics
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.
To layer mosaics:
1 Create a mosaic, then click Done
to exit the Make Mosaic dialog
box.
2 Fill, paint, and drop layers to create
your background.
3 When you return to Make Mosaic,
your background image remains
and you can place tiles over the top
of it.
Removing tiles placed on an image
reveals the grout, not the image.
Fitting Tiles Together
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.
For more information on removing
tiles, refer to “Reset Mosaic” on
page 357.
Mosaic Commands
Once you have created a mosaic, you
can use several powerful mosaic
features to improve your image.
Reset Mosaic
This command removes all tiles from
the document. Corel Painter clears the
canvas, leaving only the grout color.
If you want to remove tiles selectively,
use the Remove Tile tool discussed in
“Applying and Removing Tiles” on
page 352.
Re-Render Mosaic
This command re-creates the mosaic
from the grout color and the tile object
information. Re-rendering first fills
the image with the grout color and
then re-renders the mosaic tiles at the
resolution of the document. You can
use this command to change the
resolution of the tiles, after you
change the resolution of your
document.
To re-render tiles:
1 Open an image that is the size you
want.
2 Create a mosaic, and click Done to
exit the Make Mosaic dialog box.
3 Choose Canvas menu > Resize.
In the dialog box, disable the
Constrain File Size option and set
the resolution to a higher value.
When Corel Painter finishes
resizing, you’ll notice the tiles have
