Grain Adds texture to an image by simulating different kinds of grain—regular, soft,
sprinkles, clumped, contrasty, enlarged, stippled, horizontal, vertical, and speckle.

Mosaic Tiles Draws the image as if it had been made up of small chips or tiles and adds
grout between the tiles. (In contrast, the Pixelate > Mosaic filter breaks up an image into
blocks of different colored pixels.)

Patchwork Breaks up an image into squares filled with the predominant color in that area
of the image. The filter randomly reduces or increases the tile depth to replicate the
highlights and shadows.

Stained Glass Repaints an image as single-colored adjacent cells outlined in the

Texturizer Applies a texture you select or create to an image.
Video filters and effects
The Video submenu contains the De-Interlace and NTSC Colors filters or effects.
De-Interlace Smooths moving images captured on video by removing either the odd or
even interlaced lines in a video image. You can choose to replace the discarded lines by
duplication or interpolation.

NTSC Colors Restricts the gamut of colors to those acceptable for television repro-
duction to prevent oversaturated colors from bleeding across television scan lines.

Using the Object Mosaic filter
The Object Mosaic filter creates sharp definition in an image by clustering pixels of similar
color values together into individual tiles. You can control the tile size, the spacing
between tiles, and the total number of tiles, and you can preserve the proportions of the
original image when creating the mosaic copy.

between tiles, and the total number of tiles, and you can preserve the proportions of the
original image when creating the mosaic copy.
The Object Mosaic filter works with any bitmap image format that Illustrator can place,
and with bitmap images created with the Rasterize command. The Object Mosaic filter
creates a tiled vector version of the bitmap image. You can choose to keep the original
image or delete it.

To create a tiled effect on a copy of a bitmap image:
1 Select a bitmap image. The image must be embedded, not linked.
2 Choose Filter > Create > Object Mosaic.
The dimensions of the bitmap image are displayed at the top left of the Object Mosaic
dialog box.
dialog box.
3 Choose from the following options:
•
To set the width and height of the mosaic in points, enter values for New Size.
•
To set the distance in points between each tile in the mosaic, enter values for Tile
Spacing.
•
To set the number of tiles horizontally and vertically in the mosaic, enter values for
Number of Tiles.
•
To lock the width or height dimensions to those of the original bitmap image, choose
Width or Height for the Constrain Ratio option. Choosing Width calculates the appro-
priate number of tiles to use for the width of the mosaic, based on the original number
