A web server is a *program*, just as a word processor is a program. You can run programs on personal computers. You can run a web server program on a personal computer. That is, a personal computer *IS* a web server if you have installed web server software on it. In that case, how to get Perl running on a personal computer also covers how to get Perl running on a web server, since that personal computer is also a web server! Perhaps you meant how to get Perl running on disparite Operating Systems? -- Tad McClellan email: perl -le "print scalar reverse qq/moc.liamg\100cm.j.dat/" The above message is a Usenet post. I don't recall having given anyone permission to use it on a Web site.

But my first thought upon reading this post was that I would probably look at Imagemagick. It is (IMO) an outstanding tool to manipulate and/or create images. It runs happily on Windows boxes, Unix, whatever, does not seem to be an unseemly resource pig, and is very easy (perlmagick) to control from a perl script/program. Yes, a person would have to write code to tell Imagemagick what you wanted it to do, but based on the OP requirements, it would seem to be relatively trivial. What am I missing or not thinking of?

Your comments are a little difficult for me to understand. Since early in 2009, at several Web sites I have had a fairly sophisticated Perl language .exe program available as a downloadable freeware program for science researchers around the world. I wrote the entire program myself. The latest update that is not yet available for downloads is about 7000 lines of code long. My questions in this Newsgroup usually involve Perl usages that I myself have not attempted in the past such as running script that can visit a Web site and capture and return data and files. I had to ask some questions here about that script earlier this year because it would not work with my programs. And what I eventually discovered after getting opinions from people is that my virus software was keeping the script from working. The error messages being generated did not clearly point in that direction. Adjustments were made to the virus software to resolve the problem. Also, I have clearly stated repeatedly in the past that I consider Perl to be perhaps one of the best languages available for science researchers to use. It is so versatile. And this present effort involves attempts to get some documentation prepared that will make it easier for researchers to see how they could be using the Perl language with their efforts. If you yourself are a Perl fan, then why not encourage that type of effort? |
