<P><FONT SIZE=2>Uporabis lahko paket pbmplus, iz njega pa programa pamsumm in pnmgamma:</FONT>
</P>
<P><FONT SIZE=2>SYNOPSIS</FONT>
</P>
<P><FONT SIZE=2> pamsumm { -sum | -mean | -min | -max } [-normalize] [-brief] [imagefile]</FONT>
</P>
<P><FONT SIZE=2> All options can be abbreviated to their shortest unique prefix. You may use</FONT>
<BR><FONT SIZE=2> two hyphens instead of one. You may separate an option name and its value</FONT>
<BR><FONT SIZE=2> with white space instead of an equals sign.</FONT>
</P>
<P><FONT SIZE=2>DESCRIPTION</FONT>
</P>
<P><FONT SIZE=2> This program is part of Netpbm.</FONT>
</P>
<P><FONT SIZE=2> pamsumm reads a Netpbm image (PNM or PAM) and performs a summary function</FONT>
<BR><FONT SIZE=2> over all the samples in all the rows, columns, and planes and prints the</FONT>
<BR><FONT SIZE=2> result to Standard Output.</FONT>
</P>
<P><FONT SIZE=2> pamsumm performs the operation on the actual sample values, not on the light</FONT>
<BR><FONT SIZE=2> intensities represented by them in the case that the image is a PGM or PPM</FONT>
<BR><FONT SIZE=2> image or PAM equivalent. If you want to do arithmetic on light intensities</FONT>
<BR><FONT SIZE=2> of such a visual image, you can use pnmgamma to convert it to one with</FONT>
<BR><FONT SIZE=2> samples proportional to light intensity, and then use pamsumm on the result.</FONT>
</P>
<P><FONT SIZE=2> If you want to summarize by column (e.g. add up the columns separately), use</FONT>
<BR><FONT SIZE=2> pamsummcol. If you want to summarize by row, use a combination of pamsummcol</FONT>
<BR><FONT SIZE=2> and pamflip. If you want to summarize a particular plane, use pamchannel to</FONT>
<BR><FONT SIZE=2> extract it and then pamsumm.</FONT>
<BR><FONT SIZE=2> </FONT>
<BR><FONT SIZE=2>Cesa podobnega, kar ti isces, se nisem pocel, paket pa je primeren za poganjanje v paketni obdelavi, potem ko ze ves, kaj isces.</FONT></P>
<P><FONT SIZE=2>Lep pozdrav,</FONT>

<P><FONT SIZE=2>Omislil sem si Webcan, pa me zanima, če mogoče pozna kdo kako orodje, ki lahko določi svetlost slike?</FONT>
</P>
<P><FONT SIZE=2>Problem:</FONT>
<BR><FONT SIZE=2>Ko pride noč bi recimo preklopil prikaz iz žive slike na neko shranjeno sliko in zkutraj, ko je svetloba dovolj velika spet nazaj.</FONT></P>
<P><FONT SIZE=2>Se pravi nekaj takega:</FONT>
<BR><FONT SIZE=2>analitzraj sliko.jpg --> vrne recimo svetloba = 30% ali kaj podobnega.</FONT>
