calling external program tiff2pdf

[John]

Hi

Part of program

my $filename="fred.tiff";
my $newfile="john.pdf";
system ("tiff2pdf -o $newfile $filename");

There is no conversion.

I've tried "./tiff2pdf" also.

Any ideas?
John

my $filename="fred.tiff";
my $newfile="john.pdf";
system ("tiff2pdf -o $newfile $filename");

There is no conversion.

I guess you shouldn't have a space between the '-o' and the
'$newfile'.

Hi

Tried that but it didn't work.
It is strange since it works on the linux command line when I key in
tiff2pdf -o john.pdf fred.tiff
Odd.

Hi, all

Manage to crack it. You need to place all parameters in quotes including
the -o.

system ("tiff2pdf","-o","$newfile","$filename")

Many thanks
John

Nope, you misunderstand what you did here. The quotation marks above are
not important. What is important is the fact that you passed system a LIST
rather than a single string which by-passed the shell. I am assuming the
actual $newfile and $filename contained some characters that were
problematic for the shell.

perldoc -f system

Read the documentation for the functions you use.

Hi

I always read the documentation whenever I have a problem with a particular
construct. Well, at least my Perl nutshell.
$newfile and $filename only contained fred.tiff and john.pdf.
What system is expecting is an array.
Thanks for input.

Regards
John

Then the problem is in the part that you didn't show, or you didn't
copy/past the part literally.

If you for example used single quotes in the real version, that would
explain it.

What did Dan's code show you?

Hi

I cut and pasted. The solution is you need to give a list as I mentioned
earlier.
Many thanks for your input.

You make great Gazelle bicycles.

Then it might be a permissions problem then. Make sure the script has rw
access to the dir the pdf will be written in.

Also, $newfile and $filename don't need double quotes around them. Just
pass them straight:

system ('tiff2pdf', '-o', $newfile, $filename);

Hi

I had already chmod and I could r/w.
Many thanks for input

Its not though, I've never done that(given a list), and using the code
you posted it works for me. Something else is up...

I used this as the full program:

my $filename="fred.tiff";
my $newfile="john.pdf";
system ("tiff2pdf -o $newfile $filename");

worked just fine.

I had a similar issue with system and imagemagik. From the command
prompt the command and the passed parameters worked great, from
system() it never worked. I finally figured out for some reason I have
to give the full path to imagemagik in the system() command for it to
work. Not sure if this will work for you but did for me.
