spectro/synthcal
Summary
Create synthetic calibration file. The default is a linear
calibration file.
Usage
synthcal [-options] basename
The -r
parameter selects the table resolution. The default is 256.
The -t
option selects the type of device the calibration file is intended
for. Default is display.
The -d
option selects the device colorspace. The default for input and
display is Video RGB, while the
default for output is CMYK.
The -D parameter modifies the colorspace
set by -d by allowing
individual colorants to be added or subtracted from the colorspace.
Optionally it can be used to create a non-linear calibration file,
useful for diagnostics. Each of the device channel curves can be
given a gamma (power curve) shape, scaled to a maximum other than
1.0, and offset from a value other than 0.0. If less than the number
of channels values is set in -o, -s or -p, then the last value will
be extended to the remaining channels.
