Hum, and there's also another case that doesn't work.
If I have a 2 band image as source:
$ ./tools/tiffcp 2band.tif out.tif -c jpeg -p contig JPEGLib: Bogus input colorspace. out.tif: Error, can't write strip 0.
So, I'd also suggest changing:
if (td->td_photometric == PHOTOMETRIC_MINISWHITE || td-
>td_photometric == PHOTOMETRIC_MINISBLACK)
sp->cinfo.c.in_color_space = JCS_GRAYSCALE;
into:
if == PHOTOMETRIC_MINISWHITE || td- ((td->td_photometric
>td_photometric
== PHOTOMETRIC_MINISBLACK) && td->td_samplesperpixel == 1)
sp->cinfo.c.in_color_space = JCS_GRAYSCALE;
