How to turn on IM log?

[chris331335]

hi,

I am new to ImageMagick. Can anyone tell me how to turn on IM log?

I have changed log.xml as below, but I still can not see the log. Appreciate your help!

<logmap>
<log events="all"/>
<log output="file"/>
<log filename="Magick-%g.log"/>
<log generations="3"/>
<log limit="2000"/>
<log format="%t %r %u %v %d %c[%p]: %m/%f/%l/%d\n %e"/>
</logmap>

By default, no log is generated. To enable it, add -debug something to your command line. For example, -debug all.
