# LUTify

  

A very complete and simple script to resize, combine/mix 2 luts or convert your CLUT images to CUBE format and viceversa.

## FEATURES:

  

* Auto-detect input format

* Auto-resize not perfect square LUT size(example #33, #17...)

* Flip RGB values

* Change size and shape of your LUT (example Spark AR LUTs to Lens Studio 1x16 LUTs)

* Generate identity CLUT

* Read all types of CLUT

* Combine 2 luts and specify the amount from lut1 (0) to lut2 (100)

* Two type of interpolation when resizing: Tetrahedral or Nearest

Square:

Square one-row:

Hald:

## REQUIREMENTS:

* Python 3

* Numpy

* Pillow

  

```Shell

$ pip install numpy pillow

```

  

## USAGE:

  

```Shell

$ LUTify.py -h

usage: LUTify.py [-h] [--input INPUT] [--combine COMBINE] [--mixer MIXER]

[ --preserve] [--output OUTPUT] [--format {hald,square}] 

[--identity] [--size SIZE] [--method {nearest,tetrahedral}]

[--rows ROWS] [--flip]

...

```

*  `-i INPUT`/`-o OUTPUT`supports .CUBE, .PNG, .JPG, .TIFF

* `-c COMBINE`/ supports .CUBE, .PNG, .JPG, .TIFF, optionals:

- - `-p PRESERVE` when combining 2 luts preserve the max size between them, default false

- -  `-x MIXER` mix amount from lut1(0%) to lut2(100%), default is 50

*  `-id IDENTITY` generate a CLUT identity

*  `-f FORMAT` "hald" or "square", override default output:

- - if output is CUBE or "identity", default format is "hald"

- - if input is CUBE and output is image the default format is "hald"

- - if input is image and output is image default format will be automatically determinated as the opposite of the input format.

*  `-s SIZE` choose your CLUT size or LUT size overriding input value.

*  `-m METHOD` the method of interpolation when resizing between "tetrahedral"(default) and "nearest"

*  `-r ROWS` number of rows when output is square

*  `-ud FLIP` flip upside down RGB values

  

## TIPS:

If you would like to convert your Spark AR LUTs to Lens Studio:

```Shell

$ LUTify.py -i "SparkAR_SQUARE.png" -o "LensStudio_SQUARE.png" -s 4 -r 1 -f square --flip

```
