Hello, I'm using GNU Octave, When I ran:<br> I = imread ("mypic.png");<br>I got:<br>warning: your version of GraphicsMagick limits images to 8 bits per pixel<br><br>After I google it, I got the reason in<br>
<a href="http://octave.1599824.n4.nabble.com/GraphicsMagick-limitations-td3523937.html">http://octave.1599824.n4.nabble.com/GraphicsMagick-limitations-td3523937.html</a><br><br>"<br>GraphicksMagick can be built with:<br>
--with-quantum-depth=8
<br>--with-quantum-depth=16
<br>--with-quantum-depth=32
<br clear="all">"<br><br>I also track a related bug in debian:<br><a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=557879">http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=557879</a><br><br>But I still don't know how to deal with it. Do I need to build GraphicsMagick with <br>
--with-quantum-depth=16
myself? Or if I could compile it from source? <br><br>Any suggestions?<br><br>-- <br>Best Regards<br>
