Re^5: Use of uninitialized value $pic

Hi, just a thought. Shouldn't

 $iutImage->Read(@_);  # get the image under test (iut)
[download]

my $x = $iutImage->ReadImage($_[0]);
warn "$x" if "$x";
[download]

Also, you can try passing \$pic to pass the object by reference.

Hi I don't know. What does this do: `warn "$x" if "$x";` [download] Google tells me it's a warning. Undef?? dazz	[reply] [d/l]

It's a very ugly hack for error checking. See "Handling Exceptions" in the documentation of Image::Magick. Sane error handling would use die or the XS equivalent of die inside the Image::Magick code, but now it's too late for an incompatible change.

Hi This is running on a headless system. Does that mean I should use: `my $iutImage = $_[0]->Clone(); warn "$x" if !ref($x); # print the error message $x =~ /(\d+)/; syslog(LOG_ERR, "Attempt to clone image failed. Error: $1"); # log + the error number` [download] If the "warn" command sends error messages to the terminal, how do I send those messages to syslog??
