44   Print only unique values in the output, skipping runs of equal pixels.
45 + For reverse conversions, the
46 + .I \-u
47 + option writes uncompressed output rather than the standard run-length RGBE
48 + encoding.
49   Specifying
50   .I \+u
51   turns this option off, which is the default.

80   Skip the specified number of bytes on the input header.
81   This option is useful for skipping unintelligible headers in
82   foreign file formats.
79 (Does not work when reading from standard input.)

84   .BI \-e \ exposure
85   Adjust the exposure by the amount specified.

184   default.
185   .TP
186 + .BI \-p " xr yr xg yg xb yb xw yw"
187 + On reverse conversion, RGB input uses the given set of color primaries.
188 + These are written into the output header with the PRIMARIES variable.
189 + .TP
190 + .BR \-pXYZ
191 + On reverse conversion, input is in CIE XYZ coordinates, rather than RGB.
192 + The Y channel is assumed to be in candelas/meter^2.

194   .BI -y \ res
195   Set the output y resolution to
196   .I res.
