.SH DESCRIPTION |
| 16 |
.I Getinfo |
| 17 |
reads the header of each RADIANCE |
| 18 |
.I file |
| 19 |
and writes it to the standard output. |
| 20 |
Octree and picture files are in a binary format, which makes |
| 21 |
it difficult to determine their content. |
| 22 |
Therefore, a few lines of text are placed at the beginning |
| 23 |
of each file by the RADIANCE program that creates it. |
| 24 |
The end of the header information and the start of the |
| 25 |
data is indicated by an empty line. |
| 26 |
The |
| 27 |
.I \-d |
| 28 |
option can be used to print the dimensions of an octree or |
| 29 |
picture file instead. |
| 30 |
For an octree, |
| 31 |
.I "getinfo \-d" |
| 32 |
prints the bounding cube (xmin ymin zmin size). |
| 33 |
For a picture, |
| 34 |
.I "getinfo \-d" |
| 35 |
prints the y and x resolution (-Y yres +X xres). |
| 36 |
If no |
| 37 |
.I file |
| 38 |
is given, the standard input is read. |
| 39 |
.PP |
| 40 |
The second form of getinfo with a hyphen simply removes the header |
| 41 |
and copies the body of the file from the standard |
| 42 |
input to the standard output. |
| 43 |
.SH EXAMPLE |
| 44 |
To print the header information from scene1.oct and scene2.pic: |
| 45 |
.IP "" .2i |
| 46 |
getinfo scene1.oct scene2.pic |
