### Pack of tools for proper color managing AviSynth+.
### From function transforms like performant piecewise gamma functions,
### to color gamut converters and a list of building block functions
### for matrix operations.
###
### All of them converge in ConvertFormat(). A simple and accurate to use
### All-In-One (AIO) filter to scale, convert and transform colors.
###
### ConvertFormat() supports color space, color model, transfer function, color range,
### chroma placement and chroma subsampling conversions among other features
### like chroma reconstruction, 'no ring' scaling, luma space scaling, and no-moirée scaling.
###
### ConvertFormat() replaces my old filter LinearResizer() (Dither Tools based)
### and is clearly inspired by cretindesalpes' fmtconv and avsresize's z_ConvertFormat().
### For a "no-fuss" high quality resizer you can use deep_resize() from ResizersPack.
###
###
### Dependencies: AviSynth+ 3.7.2+

###
### ConvertFormat()
###
###
### Similar to avsresize's z_ConvertFormat() but more flexible, more options and more features:
### More color models and color space conversions, chroma reconstruction, scale_space, noring, mod size, ratio resize, kernel/matrix aliases (supports any resizer), presets, show settings, etc
###
### Dependencies: AviSynth+ 3.7.2 and over
### ExTools
### GradePack (for show=true and 'sigmoid' scaling)
### MasksPack (for show=true)
### ResizersPack (for show=true)
### KNLMeansCL (for UVRecon=true)
### nnedi3 (for UVRecon=true)
### SysInfo (for UVRecon=true)
### Optional resizer plugins (check links)
###
### Example 1 - Limited YUV to full RGB:
### ConvertBits(10,fulls=false) # RGB conversion from YUV requires at least 10-bit precision
### ConvertFormat(1,1,"YUV","RGB")
###
### Example 2 - Downscale HD Rec.709 YUV to SD 170M YUV:
### ConvertFormat(720,0,kernel="SSIM2") # 0 stands for automatic size given width/height ratio
### or
### ConvertFormat(preset="DVD-NTSC") # Work-in-Progress
###
### Example 3 - YUV420 to YUV444 and scale up by 2 in sigmoid space with chroma reconstruction and noring (cs_out to "" or "none" to skip color space autoconversion):
### ConvertFormat(2,fmt_out="44",cs_out="",kernel="FSRCC",scale_space="sigmoid",noring=true,UVRecon=true,cplace_in="MPEG2")
###
### Example 4 - Scale down by 2 with no moirée in linear light space (typically downscaling as well as pre-blurring -for nomoiree- are done in linear light):
### ConvertFormat(0.5,kernel="RobiSharp",scale_space="linear",nomoiree=true)
###
### Example 5 - Scale width to 1280 and height to half with different kernels and taps for Luma/Chroma planes:
### ConvertFormat(1280,0.5,kernel="EWA6",kernel_c="Blackman8")
###
### Example 6 - Convert from YUV444 to YUV422 and TV range to PC range:
### ConvertFormat(1,1,fmt_out="422",tv_out=false,cplace_out="MPEG2")
###
### Example 7: High quality JPEG decoding and conversion to RGB
### MP_Pipeline("""
### ### platform: win32
### JPEGSource("source.jpg",rec=3)
### ### ###
### """)
### ConvertBits(16)
### Implicit:
### ConvertFormat(1,1,"YUV","RGB","jpeg","sRGB",UVRecon=true)
### Explicit:
### ConvertFormat(1,1,"YUV","RGB","jpeg","sRGB",false,false,true,cplace_in="MPEG1",UVRecon=true)
### ConvertBits(8, dither=1)
###

# -- untapered decay
# Welch/Welsh is a Welch-windowed sinc filter (parabolic window, 3 lobes)
# Cosine is a Cosine-windowed sinc filter (3 lobes) (Good for downscaling but also upscaling. Same as Wiener but without aliasing. Therefore very similar to Blackman6 but with a bit of ringing)
# Bessel is a unnormalized sinc filter (3 lobes)
# -- tapered decay (in order)
# Bartlett is a Bartlett-windowed sinc filter (4 lobes) (actually the same mathematical function used for a 'Triangle' filter, as well as the 'Bilinear' interpolation filter)
# Sinc is a Sinc-windowed sinc filter (4 lobes)
# Hamming is a Hamming-windowed sinc filter (4 lobes) (has a gradient discontinuity so not recommended)
# Hann(ing) is a Hanning-windowed sinc filter (4 lobes) (2-lobes can be used for upscaling sharp images) (Just like Blackman6 bit a tiny bit softer)
# Kaiser is a Kaiser-windowed sinc filter (4 lobes) (also a small gradient discontinuity so not recommended)
# Bohman is a Bohman-windowed sinc filter (6 lobes) (Blackman would fall between Kaiser and Bohman)
# Parzen is a Parzen-windowed sinc filter (8 lobes) (Very similar to Blackman6)
# Ginseng is a Jinc-windowed sinc filter (3 lobes). Better for HBD than ewa_lanczos3. Very similar to spline36 aliasing wise, but sharper. Also adds some bloating.
# -Lagrange is a Lagrange cubic polynomial filter that approximates a windowed filter https://legacy.imagemagick.org/Usage/filter/#lagrange
# -Jinc/Bessel is a Box-windowed jinc filter (3.2383154841662362 lobes). Jinc filters are not separable so they're usually slower than sinc, cubic, etc but more pleasant artifacts. See here: https://legacy.imagemagick.org/Usage/filter/#cylindrical
# -ewa_hanning is a Hanning-windowed jinc filter (3.238 lobes).
# -ewa_ginseng is a sinc-windowed jinc filter (3.238 lobes).
# ewa_lanczos is a lanczos-windowed jinc filter (3.238 lobes). Under same circumstances -in this case 'taps'- Jinc (radial) is always sharper than their Sinc (orthogonal) equivalent. Check ewa_lanczosradius3 below.
# ewa_lanczossharp is a lanczos-windowed jinc filter (3.238 lobes). Slightly sharpened as per calculations by Nicolas Robidoux, his preferred all-around scaler. Can be replicated with Jinc filter and blur = 0.9812505644269356
# ewa_lanczossharpest is a lanczos-windowed jinc filter(3.238 lobes). Very sharp, technically not recommended by Robidoux except when downscaling. Can be replicated with Jinc filter and blur = 0.88549061701764
# ewa_lanczos2sharp is a lanczos-windowed jinc filter(2.2331305943815286 lobes). Good alternative to the other EWAs when you don't want the moiree or "hash pattern blur" artifact, so use this for dithered content or RobiSharp.
# ewa_lanczosradius3 is a lanczos-windowed jinc filter(3 lobes). More sharpened than ewa_lanczossharp and very similar to Ginseng tensor, good for up and downscale. Can be replicated with Jinc filter and blur = 0.9264075766146068 (scales lobes from 3.238 to 3)
# ewa_lanczos4 is a lanczos-windowed jinc filter (4.2410628637960699 lobes).
# ewa_lanczossoft is a lanczos-windowed jinc filter (3.238 lobes). Softened instead. This one makes hash patterns disappear completely (blur determined by trial and error). Can be replicated with Jinc filter and blur = 1.015. https://github.com/mpv-player/mpv/blob/27c38eac1040cd781f39d977ce53adcd65ddcfb6/video/out/filter_kernels.c#L380
# -Haasnsoft is a Hanning-windowed jinc filter (3.238 lobes). Removes almost all aliasing. Blur value to match orthogonal and diagonal contributions on a regular grid. Can be replicated with Jinc filter and blur = 1.11
# -Tukey is a Hanning-windowed jinc filter taper = 0.5
# Quadratic/Quadric/Bell like Cubic but 66% faster (1.5 taps/lobes). Also known as 'Bell' -> https://clouard.users.greyc.fr/Pantheon/experiments/rescaling/index-en.html#bell
# -RAVU / RAISR similar to XBR and nnedi3
# -NGU Next Generation Upscaler. madVR edge directed NN algo (closed source, similar to FSRCNN)
# -Sphinx Continuation of Sinc and Jinc, interpolating all three dimensions at the same time using a carefully constructed filter that has a perfectly spherical frequency response. 1.4302966531242027, sphinx window.
# -ICBI (Iterative Curve Based Interpolation) is a single image superresolution technique described in Fast artifact-free image interpolation by Andrea Giachetti and Nicola Asuni, presented at BMVC 2008
