I am trying to convert 16-bit GRAY files to 8-bit JPEG or PNG format. Since the original images are actually 12-bit, I assume that I need to right-shift each pixel, so I'm using a command like
convert -size 512x512+3416 -depth 16 -evaluate RightShift 4 -endian LSB gray:c_vf1169.fre c_vf1169_rs4_lsb.png The effect seems to be that the high-order byte is simply ignored when the right-shift is done. Could someone please explain what I'm doing wrong? I'm using IM 6.2.4 Q16 as distributed by Debian. I apologize if this is really obvious, but I haven't been able to figure it out or find an answer. - Robert _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
