| Hi all,
I need to convert JPEGS to Grayscale TIFS
Large Size JPEGS.
Which is the best module I should opt for ?
Thanks.

ImageMagick is your best bet.

=46unny, I just asked how to install Image::Magick on Mac OS X at macosx@p=
erl.org and was told to use Imager instead. So I'll post my question again:
I try to install the Image::Magick module. ImageMagick itself was installed=
by a TeX distribution (gwTeX), and I found:
drwxr-xr-x 14 root admin 476 22 Mar 12:15 Magick++
-rw-r--r-- 1 root admin 389 7 Feb 16:00 Magick++.h
drwxr-xr-x 3 root admin 102 10 Nov 00:26 freetype2
-rw-r--r-- 1 root admin 3814 4 Jan 21:31 ft2build.h
drwxr-xr-x 18 root admin 612 22 Mar 12:14 libwmf
drwxr-xr-x 33 root admin 1122 22 Mar 12:15 magick
-rw-r--r-- 1 root admin 755 7 Feb 17:03 uninameslist.h
in ./usr/local/include/.
Now the installation instructions tell me to=20

The actual settings are:
# Header search specfication and preprocessor flags
'INC' =3D> '-I../ -I.. -I/usr/include/freetype2 -I/usr/X11R6/include =
-I/usr/X11R6/include/X11 -I/usr/include/libxml2',
# Library specification
'LIBS' =3D> ['-L/usr/local/lib -L../magick/.libs -lMagick -L/usr/X11R6=
/lib -L/usr/lib -L/usr/lib -llcms -ltiff -lfreetype -ljpeg -lpng -ldpstk -l=
dps -lXext -lSM -lICE -lX11 -lbz2 -lxml2 -lz -lpthread -lm -lpthread'],
Can someone tell me which paths I should enter to successfully compile Perl=
Magick? I did not find something like "ltiff" or "ljpeg", but the convert t=
ool works fine with these formats.
Thanks,
Jan

These are my principles and if you don't like them... well, I have others. =

Saw your message there. Imager might be a good choice for you overall,
but then that isn't really what you asked. Assuming you have good
reasons to want Image::Magick, then it is a fine module. I was also
hoping someone with a bit more OS X experience would suggest how to
solve this the "Apple Way".

The above will need a -I/usr/local/include added to it to specify that
path as part of the includes path.

This one surprises me, generally there will be a libjpeg.so, etc. in a
library path. You need to make sure the path to the .so files is
included in the list above, which I would have thought they would be in
/usr/local/lib based on your include path, but if they come with the dev
tools in OS X then god knows where it puts them. On linux for instance
there is a ld.so.conf that specifies what directories to include when
looking for the shared libs. There should be something similar assuming
gcc is being used. Alternatively you can specify these types of paths
either in an ENV variable, LD_LIBRARY_PATH for instance, but I don't
know precisely off the top of my head, usually I guess my way through it
:-).

You won't (likely) find an ltiff path, instead it will be libtiff.so or
some such. Look for the shared lib files and see if you can add the
paths to them to the above switches.
Good luck,

That's what Sherm Pendley suggested, too, but it did not suffice.

I checked /usr/local/lib, and it does have ImageMagick libs in it, no .so f=
iles, though:
drwxr-xr-x 11 root admin 374 22 Mar 12:15 ImageMagick-5.5.1

I seem to have started a rather extensive thread on macosx@perl.org, so I g=
uess we should keep this there.
Thanks,
