TODO

General

• maybe color the 'usage' text a little ?
• maybe add syntax to chain image functions together
  • possibly using '--' to seperate actions
  • need to figure out input/output file(s)
  • is there a need for multiple-in / multiple-out ?
• samplers seem to have a n off-by-one issue (see dotnet run -- areasmoother salieri-bx.png -t 2 --max-threads 1 --sampler 2)
• use private static readonly ImageComparer ValidatorComparer = ImageComparer.TolerantPercentage(0.05f); instead of custom comparer for image tests
• refactor wiki generator to use msbuild task instead of tests

Ideas

• add noise functions
  • perlin
  • opensimplex - https://gist.github.com/digitalshadow/134a3a02b67cecd72181
  • simplex ?
  • maybe add random points and then draw gradients between closest ones (use trie?)
    • might be able to do this little by little
      1. random points in an area
      2. add gradients
      3. save border points for next area
      4. repeat
• maybe do a tree ring expanding from random cener points
  • for each pixel
  • find nearest starting point (trie?) - dotnet add package KdTree
  • calculate distance to point
  • color pixel based on distance
• take a look at https://en.wikipedia.org/wiki/Rose_(mathematics)
  • https://en.wikipedia.org/wiki/Spirograph
  • https://en.wikipedia.org/wiki/Maurer_rose
• spiral graphs
  • remove/keep prime number spots
  • make rotation distance configurable (best one is golden ratio)
• maze generator
  • http://www.neocomputer.org/projects/eller.html
  • prims
  • others.. there's lots
• fermats last theorem graph
  • plot result of x^2 + y^2 distance from whole number
  • add option to change exponent (2 is the only one that has answers to x^2+y^2=z^2)
  • add option to change starting point
• Implement blind deconvolution
  • https://github.com/tianyishan/Blind_Deconvolution

AreaSmoother

• create an areasmoother that samples surrounding pixels then weighted-averages them based on distance - similar to original but without picking the 'best' vector
• AS2 has an off-by-one error when using --rect option

PixelateDetails

• Paralellize and add progress bar
• add a mode where borders inside of boxes are added
  • border color options [average, original, user specified color]
  • fill options [average, original, user specified color]
  • need to come up with color input parser
    • rgb 0-255 : "127,63,255"
    • rgb decimals : "0.5,0.25,1.0"
    • rgb percent : "50%,25%,100%"
    • rgb Hex : "#7F3FFF"
    • other color spaces ?
  • maybe include option to specify which boders to render ? (nesw) or (trbl)

Derivatives

• Paralellize and add progress bar
• maybe add other types of derivatives

ZoomBlur

• add a vertial / horizontal only zoom blur (curtain blur ?)

Swirl

• is it possible to do a outer swirl (outside of radius towards edge instead of inwards?)

Encryption

• add option to change key size? supposedly options are (128,192,256)

Deform

• maybe implement fisheye

AllColors

• add arrangements
  • left to right / right to left
  • spiral in to out
• add option to invert sort order

SpearGraphic

• breakout Third and Fourth into their own generators
• add a way to change the default control variable values
• add support for rectangle option '-#'

ColatzVis

• not really working well.. need a new visualization

UlamSpiral

• add spacing between x,y points so we can draw dots with size based number of factors
• add support for color pallete
• add option to invert dot size - dot size for primes is max, and smallest for many divisors
• add option to switch between sphere and disk dots
