51   For a picture,
52   .I "getinfo \-d"
53   prints the y and x resolution (\-Y yres +X xres).
54 + The
55 + .I \+d
56 + option prints the header followed by a newline and the dimensions.
57   If no
58   .I file
59   is given, the standard input is read.
# Line 58 | Line 65 | and copies the body of the file from the standard
65   input to the standard output.
66   If the

68 < option is included, then the resolution string will be elided as well.
