>usually the Perl module has to be installed separately

Sorry, I meant that the Perl module comes with installing ImageMagick itself if you do it from source. From my experience installing it from source is straightforward (they make it so necessarily). Just a thought I wanted to mention since I've use gone down a similar route with image manipulation. I didn't do any shrinking, but added some watermarks to images I was serving. I also served up different "sizes". But it was all done via the Perl library, not convert itself. Anyway, I think your use of Perl is really neat here.

"Sorry, I meant that the Perl module comes with installing ImageMagick itself if you do it from source." This is not true. As documented a default install does not build Image::Magick. You can see problems just by looking at the test matrix and open bugs. See also Cannot compile Image::Magick.	[reply]

You can see problems just by looking at the test matrix IIRC (it's been a long time), installing it from CPAN never really worked well (or at all?); I remember the Perl module would get built when one complied ImageMagick from source. But even then, finnicky business I think. In any case, Imager is a nice alternative ("Nicholas Clark - How Geizhals took out ImageMagick before ImageMagick took us out"), and I haven't tried GraphicsMagick.	[reply]

Well, thanks for the heads up. It's been a while since I installed IM so I might have been pretty baffled if I did it again now. `$ ./configure --with-modules --enable-shared --with-perl` [download] Ah well there you go.	[reply] [d/l]
