Unavailable effect and filter commands
Effect and filter commands are dimmed when they aren’t available for the targeted item. For example, the command
may work on vector objects, but not on bitmap images.
Following are some guidelines to help you determine when effects and filters are available.
All of the commands in the top section of the Effect menu (3D, Convert To Shape, Distort & Transform, Path,
Pathfinder, Rasterize, Stylize, SVG Filters, and Warp) can be applied to vector objects. These same effects won’t affect
a bitmap object unless you apply the effect to a fill or stroke added to the object in the Appearance palette; the excep­
tions to this are the effects in the 3D, SVG Filters, and Warp submenus, and the Transform, Drop Shadow, Feather,
Inner Glow, and Outer Glow effects, which will affect a bitmap object. All of the commands in the bottom section of
the Effect menu (starting with Artistic) are raster effects and can be applied to either bitmap or vector objects. When
these raster effects are applied to an object, they use the document’s raster effects settings.
Important:
The effects and filters in the Artistic, Brush Strokes, Distort, Sketch, Stylize, Texture, and Video submenus
aren’t available with documents in CMYK color mode. If an RGB document that uses any of these commands is
converted to CMYK, the effects remain listed in the object’s Appearance palette but don’t affect the object’s appearance.
All of the commands in the top section of the Filter menu (Colors, Create, Distort, and Stylize) can be applied to
vector objects (with the exception of Object Mosaic), but only some commands in the Create and Colors submenus
can also be applied to bitmap objects. All of the commands in the bottom section of the Filter menu are raster filters
and can be applied to bitmap objects, but not to vector objects or 1-bit (black-and-white) bitmap objects.
About raster effects
Raster effects are effects that generate pixels, rather than vector data. Raster effects include SVG Filters, all of the
effects in the bottom section of the Effect menu, and the Drop Shadow, Inner Glow, Outer Glow, and Feather
commands in the Effect > Stylize submenu.
Whenever you apply a raster effect, Illustrator uses the document’s raster effects settings to determine the resolution
of the resulting image. These settings have a large impact on the resulting artwork; therefore, it’s important to check
the document raster effects settings before you start working with filters and effects.
You set rasterization options for a document by choosing Effect > Document Raster Effects Settings. (See “Raster­
ization options” on page 424.)
If an effect looks good on-screen, but loses detail or appears jagged when printed, you need to increase the document
raster effects resolution.
Rasterization options
You can set the following options for all raster effects in a document or when you rasterize a vector object.
Color Model
Determines the color model that is used during rasterization. You can generate an RGB or CMYK color
image (depending on the color mode of your document), a grayscale image, or a 1-bit image (which may be black
and white or black and transparent, depending on the background option selected).
Resolution
Determines the number of pixels per inch (ppi) in the rasterized image. When rasterizing a vector object,
select Use Document Raster Effects Resolution to use global resolution settings.
