.SH "توضیحات (DESCRIPTION)"
.PP
Command line program that converts a hardcopy characteristic curve file to softcopy format\&. In other words, the measured optical density (OD) values from the input file are transformed to the luminance space according to the formula:

.PP
.PP
.nf
  L = La + L0 * 10^(-D)
.fi
.PP

.PP
where \fIL\fP is the resulting luminance, \fILa\fP is the reflected ambient light and \fIL0\fP the illumination (both measured in cd/m^2), 'D' the optical density (OD)\&. Please note that if no illumination value is specified in the input file (keyword \fIlum\fP) all optical density values are mapped to a constant luminance\&.
