Re: Error when trying to loop through DB and run a script

~~Turn on warnings, strict and diagnostics and try again. I'll bet perl will give you a few hints.~~

Update: Ignore this. They were turned on, and I missed 'em.

Reading through the error chain, it seems that the problem might be that main::setImage is passing PDF::API2::image_png an invalid object. (The hint I'm working from is the 'undefined' argument in multiple call levels...)

ikkon: You might want to try the perl debugger. I've only used it recently (due to a recent thread about it), and find it very easy to use for problems like this. Just invoke your script like: `perl -d script_name.pl` and then you can set a breakpoints, step through the code, display variable values, etc. ...roboticus	[reply] [d/l]
