Hello All!<br>

Okee doke, found a clue. I see:<br>
|
|
<p>
|
|
<a href="http://glacier.unl.edu/~samal/class/DIST/lectures/pgm.html">http://glacier.unl.edu/~samal/class/DIST/lectures/pgm.html</a><br>
|
|
<p>
|
|
This info is pgm-specific but I guessed it couldn't be too far off <br>
|
|
the mark of other p?? formats.<br>
|
|
<p>
|
|
The first two lines of the file that scanimage produces seem to be <br>
|
|
the x and y dimensions of the area scanned, usually looks like:<br>
|
|
<p>
|
|
0.1<br>
|
|
0.1<br>
|
|
P6<br>
|
|
# SANE data follows<br>
|
|
60 60<br>
|
|
255<br>
|
|
normal-looking-data...<br>
|
|
<p>
|
|
When I remove those two leading lines pnmto???? works perfectly.<br>
|
|
<p>
|
|
Any ideas what I could be doing wrong to cause these x/y lines to <br>
|
|
be inserted? <br>
|
|
<p>
|
|
Or is scanimage creating some other file type that I should be using<br>
|
|
other converters?<br>
|
|
<p>
|
|
Have a :) day!<br>
|
