# fakeread(1)

Fake test chart reader - lookup values in ICC/MPP profile.

## NAME

Fake - Fake test chart reader - lookup values in ICC/MPP profile.

## DESCRIPTION

Fake test chart reader - lookup values in ICC/MPP profile

## SYNOPSIS

**fakeread** \[-options\] profile.\[icc\|mpp\|ti3\] outfile

- **-v** \[n\]

  Verbose mode \[level\]

- **-e** flag

  Video encode device input to sepration as:

- n

  normal 0..1 full range RGB levels (default)

- t

  (16-235)/255 "TV" RGB levels

- 6

  Rec601 YCbCr SD (16-235,240)/255 "TV" levels

- 7

  Rec709 1125/60Hz YCbCr HD (16-235,240)/255 "TV" levels

- 5

  Rec709 1250/50Hz YCbCr HD (16-235,240)/255 "TV" levels

- 2

  Rec2020 YCbCr UHD (16-235,240)/255 "TV" levels

- C

  Rec2020 Constant Luminance YCbCr UHD (16-235,240)/255 "TV" levels

**-p** separation.icc Use device link separation profile on input

- **-E** flag

  Video decode separation device output. See **-e** above

- **-k** file.cal

  Apply calibration (include in .ti3 output)

- **-i** file.cal

  Include calibration in .ti3 output, but don't apply it

- **-K** file.cal

  Apply inverse calibration

- **-r** level

  Add average random deviation of \<level\>% to device values (after sep. & cal.)

- **-0** pow

  Apply power to device chanel 0-9

- **-b** output.icc

  Apply BT.1886-like mapping with effective gamma 2.2

**-b** g.g:output.icc Apply BT.1886-like mapping with effective gamma g.g

- **-B** output.icc

  Apply BT.1886 mapping with technical gamma 2.4

**-B** g.g:output.icc Apply BT.1886 mapping with technical gamma g.g

- **-I** intent

  r = relative colorimetric, a = absolute (default)

- **-A** L,a,b

  Scale black point to target Lab value

- **-l**

  Output Lab rather than XYZ

- **-s**

  Lookup MPP spectral values

- **-R** level

  Add average random deviation of \<level\>% to output PCS values

- **-u**

  Make random deviations have uniform distributions rather than normal

- **-S** seed

  Set random seed

-

  profile.\[icc\|mpp\|ti3\] ICC, MPP profile or TI3 to use outfile           Base name for input\[ti1\]/output\[ti3\] file
