.SH DESCRIPTION |
| 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. |
| 63 |
|
with a hyphen simply removes the header |
| 64 |
|
and copies the body of the file from the standard |
| 65 |
|
input to the standard output. |
| 66 |
+ |
If the |
| 67 |
+ |
.I \-d |
| 68 |
+ |
option is given, then the resolution string will be elided as well. |

The third form of |
| 71 |
|
.I "getinfo \-a" |
| 84 |
|
require the input to be in a file: |
