# Line 1311 | Line 1311 | designation, any -m option is ignored.

1312   Added -n option to mkillum for (shared memory) parallel processing.

1314 < Fixed long-standing bug in parallel processing code that only seemed
1315 < to manifest with the new mkillum -n option, where rtrace would
1316 < deadlock upon termination.

1321 > Corrected the normalization of the Gaussian reflectance model.  This will
1322 > cause an increase in specularity for low-lying light sources.
1323 > Thanks to Don Walters of Boeing and Arne Duer of the Univ. of Innsbruck

1325 > in the denominator of the normalization factor should not be present.

1331 > Enabled the -p option for primary conversion without tone-mapping
1332 > in ra_bmp.  Also provides for XYZE input conversion to RGB.

1334 > Fixed what I consider a bug in pvalue -o when taking XYZE files on input,
1335 > where it was inappropriately undoing the exposure value so that it always
1336 > reported radiance rather than XYZ values with Y in cd/m^2.
1337 >
1338 > Made it so ra_bmp only produces run-length encoded 8-bit output for
1339 > grayscale images that are tone-mapped.  This minimizes circumstances
1340 > under which output scanline order is reversed.
