Does anyone have any suggestions for additional filters? I currently
have these on the "to-do" list:
highlight/midtone/shadow level adjustment
color_function filter
In development:
find_edges
The "cartoon-like" filter. It basically works, but still needs a lot
of work.
patterned_blur
Blurs the image by an amount controlled by a pigment(the only reason
it is here is because I haven't tested it yet, it compiled fine. :-) ).
(Mostly) Finished:
stars
Generates non anti-aliased starsfield on portions on the image with
a given color.
steps
Divides smooth gradients of color into separate steps. This might
make good "terraced" height field landscapes.
normal
Displays the normal values as rgb colors, scaled into the 0-1 range.
multiply
Multiplies the image by a given color. I will probably extend it to
take a pigment.
add
Adds a given color to the image. I will probably extend it to take a
pigment.
exponent
Raises the values of each color channel to a power in the respective
channel of a given color. I will probably extend it to take a pigment.
clip_colors
Clips the colors of the image to always be less than a specified
color. I will probably modify it to take two colors, to clip to a range.
invert
Inverts the image, using the formula component = 1-component.
blur_matrix
Also called a convolution matrix(I think). Useful for directional
blurring, etc.
color_matrix
Runs the color through a 3*3 matrix. Useful in combination with
multiply, add, exponent, etc.
I will post the source code soon, hopefully later tonight.
