[gdal-dev] gdalwarp with PHOTOMETRIC=YCBCR on grey input TIF image

[Gane R]

I am using gdalwarp withe following option to convert a tif to compressed
TIF

-co COMPRESS=JPEG -co JPEG_QUALITY=80 -co TILED=YES -co PHOTOMETRIC=YCBCR
-co BLOCKYSIZE=512 -co BLOCKXSIZE=512

Will the PHOTOMETRIC option work on grey tif images. Unfortunately I don't
have such data set.

If any one have tried to convert a Grey TIF to compressed TIF with
COMPRESS=JPEG

Thanks,
Gane
