What is FilterFormula?
FilterFormula
is a Photoshop-compatible meta-plugin filter that allows you to create
your own filters by a simple language which is very similar to "C". This
makes it a unvalualble tool for all graphic designers with a computer programming
background who have not yet found the ONE plugin filter that satisfies
all their needs, or those who do not want to buy many expensive filters
when they can have one that can do all!
Its main features
are:
-
Definition of the filters in
a "C" like language, allows the use of auxiliary variables
-
Two-pass filtering (optional,
plus initializion blocks) allows to define very complex filters. The first
pass is used to collect data, in the second pass the image is actually
filtered (Color & lightness equalization, etc.)
-
Storage array up to 256 KBytes
available, many predefined variables and functions (including trigonometric
functions)
-
Supports RGB, YUV (r/o) and
HLS color models, supports alpha channel manipulation.
-
Adobe Filter Factory source
code compatible; import of .afs files and text files.
-
With the "professional edition"
version you can create royalty-free distributable stand-alone filters (You
do not have to invoke FilterFormula to apply your filter)
-
Very fast by directly creating
386+ machine code.
-
Support for special purposes:
Gamma correction tables, sort() function (for "median cut"-like filters),
bilinear interpolation
-
No need for any other files
than contained in the package (except standard Windows DLLs).
And, as an additional BONUS,
the FilterFormula package many professional filters for image enhancement
and effects in SOURCE CODE format! See the examples
page to have a look on them.
On this website we will make the best user contributed
filter sources available for all users; we are continuously developing
filters, too.
