So now that it has it I figured I could try to avail my self of the speed increase potential. Last time I looked exiftool didn't have the -stay_open option. Mostly because it has all these camera specific support functions - that I rarely need! exiftool is the most comprehensive thing I have run into so far for reading image meta data. So I am calling a windows program that is running a Perl program and embedded Perl interpreter. Interesting thing is the entire exiftool program is open source - in Perl. And it would be cool to learn how to "host" a console program in one of my programs.
So on the one hand I already have a working solution - on the other hand it would be nice to take advantage of the speed increase.
I have been using exiftool for a long time - but I have been using it the VERY slow way - by calling SHELL for every file.
