Introduction to the “Filters” Menu
The “Filters” menu
terminology, a filter
is a plug-in that modifies the appearance of an image, in most cases just
the active layer of the image. Not all of the entries in this menu meet
that definition, however; the word “filter” is often
mis-used to mean any plug-in, regardless of what it does. Indeed, some
of the entries in this menu do not modify images at all.
With the exception of the top three items of the
menu, all of the entries
are provided by plug-ins. Each plug-in decides for itself where it would
like its menu entry to be placed. Therefore, the appearance of this menu
can be completely different for each user. In practice, though, the
appearance does not vary very much, because most plug-ins come with
GIMP when it is installed, and of course
they are always in the same places in the menu.
Plug-ins are not restricted to just the
menu: a plug-in can place entries in any menu. Indeed, a number of
functions (for example,
in the menu) are implemented
by plug-ins. But the menu is the default
place for a plug-in to place its menu entries.
For general information on plug-ins and how to use them, see the section
on Plug-ins. You can find
information on the filters that are provided with
GIMP in the
Filters chapter. For filters you install
yourself, please refer to the information which came with them.
