CMYK
colors, just remove the %
sign from the line you'd like to use ...as follows:
%% CYAN MAGENTA YELLOW BLACK %{0.217 exp} {0.217 exp} {0.217 exp} {0.217 exp} setcolortransfer %{0.256 exp} {0.256 exp} {0.256 exp} {0.256 exp} setcolortransfer {0.333 exp} {0.333 exp} {0.333 exp} {0.333 exp} setcolortransfer %{0.450 exp} {0.450 exp} {0.450 exp} {0.450 exp} setcolortransferThe values must be between 0 and 1. The smaller the number - the darker the colors.
/var/lib/apsfilter/preloads/gamma.ps
in the variables PRELOADS
in the file /etc/apsfilterrc
as follows:
if [ "$COLOR" = "mono" ] ; then # GS_FEATURES="-dBitsPerPixel=1" PRELOADS="" else # GS_FEATURES="-dBitsPerPixel=24" PRELOADS="/var/lib/apsfilter/preloads/gamma.ps" fiOf course, instead of
/etc/apsfilterrc
you could also use /etc/apsfilterrc.DEVICE
.
Just replace DEVICE
with your Ghostscript-Driver.
for example:
if [ "$COLOR" = "mono" ] ; then # GS_FEATURES= PRELOADS="" else # GS_FEATURES= PRELOADS="gamma.ps" fiIt shouldn't matter if you use
PRELOADS="gamma.ps"
or PRELOADS="/var/lib/apsfilter/preloads/gamma.ps"
