Hi,
When I use "-rotate" to rotate a 8-bit PNG, the result is 16-bit. Is
there a way to preserve bit-depth?
# before rotation

PO09__1957_DEC_IONOGRAM_0010.png: PNG image data, 4720 x 2368, 8-bit
grayscale, non-interlaced
# rotate
[EMAIL PROTECTED]:11:31][/tmp/cdmp/tmp/] convert -rotate 180

Thanks,
