What is ztfy.file ?
ztfy.file is a set of classes to be used with Zope3 application server. The purpose of this package is to handle :
- custom schema fields with their associated properties and browser widgets to automatically handle fields as external files
- automatically handle generation of images thumbnails for any image ; these thumbnails are accessed via a custom namespace ("++display++w128.jpeg" for example to get a thumbnail of 128 pixels width) and are stored via images annotations
- allow selection of a square part of a thumbnail to be used as a "mini-square thumbnail".
Square thumbnails selection is based on JQuery package extensions, so the ztfy.jqueryui is required to use all functions of ztfy.file package.
How to use ztfy.file ?
A set of ztfy.file usages are given as doctests in ztfy/file/doctests/README.txt
