# ociochecklut(1)

check any LUT file and optionally convert a pixel usage: ociochecklut \<INPUTFILE\> \<R G B\> or \<R G B A\>

## NAME

ociochecklut - check any LUT file and optionally convert a pixel

usage:  ociochecklut \<INPUTFILE\> \<R G B\> or \<R G B A\>

## OPTIONS

- **-t**

  Test a set a predefined RGB values

- **-v**

  Verbose

- **--help**

  Print help message

- **--inv**

  Apply LUT in inverse direction

- **--gpu**

  Use GPU instead of CPU

- **--gpulegacy**

  Use the legacy (i.e. baked) GPU color processing instead of the CPU one (**--gpu** is ignored)

- **--gpuinfo**

  Output the OCIO shader program

OCIOCHECKLUT loads any LUT type supported by OCIO and prints any errors encountered.  Provide a normalized RGB or RGBA value to send that through the LUT.  Alternatively use the **-t** option to evaluate a set of test values. Otherwise, if no RGB value is provided, a list of the operators in the LUT is printed. Use **-v** to print warnings while parsing the LUT.
