Apache::Imager::Resize

Apache::Imager::Resize is an image resizing software that specializes in resizing images before they're delivered. This software is a simple fixup class that serves only one purpose, which is to ensure that an appropriately shrunken image file is returned. All you have to do is add either a width or a height parameter to an image file address, and AIR will do the rest. Additionally, it caches the results of each operation, so the first request might take a little longer, but subsequent similar requests should be much quicker.

While there are other modules that can perform similar tasks, AIR might be the best option for those who only require the ability to show images at an arbitrary size in a simple, clean way. In contrast, if your requirements include more complicated transformations or you're running mod_perl behind a thin proxy, a different software such as Apache::ImageMagick might be better suited to your needs.

AIR utilizes Imager as the primary tool to do the work. However, if nobody else does, the developer intends to produce a proper general-purpose Apache::Imager package. This software will end up being a special case with a simplified interface and will probably exist along with an Apache::Imager::Translate and other useful shortcut modules.

To utilize this software, all you need to do is include the following within the required configuration files:

< Files "*.jpg" >
PerlFixupHandler Apache::Imager::Resize
ImgResizeCacheDir '/imgcache'
< /Files >

Or

< Location "/liveimages" >
PerlHandler Apache::Imager::Resize
ImgResizeNoCache on
ImgResizeWidthParam 'w'
ImgResizeHeightParam 'h'
< /Location >

And on the desired web page, use the following:

In conclusion, Apache::Imager::Resize is a reliable software that rightly performs its core functions without any fuss. Its user-friendly interface and caching system make it an ideal option for users who require simple image resizing at any size.
