[magick-users] torn paper thumbnail

[Jens Augustenborg]

Hi,

I am new to IM (PerlMagick) but I can handle simple things. On
http://www.imagemagick.org/Usage/thumbnails/#torn the example is

convert thumbnail.gif \
          \( +clone -threshold -1 -virtual-pixel black \
             -spread 10 -blur 0x3 -threshold 50% -spread 1 -blur 0x.7 \) \
          +matte -compose Copy_Opacity -composite torn_paper.png


how does that look in PerlMagick??

My bonus question is: Even though the example page is good, where do I find
a comprehensive tutorial in order to go from IM command line options to Perl
syntax?

Thanks a lot
Jens
