ZIF ONE-FILE STORAGE EXAMPLE - USE ON WEB SERVER

The Zoomify Image Format (ZIF) allows storage of high-resolution, zoomable images megabytes or gigabytes in size in one single file. ZIF files can be viewed using the Zoomify Image Viewer with no need for any special server setup.*

For customers and partners with large collections of large images, this provides simple, fast viewing with convenient, efficient content management. Note that the Zoomify Converter can easily convert Zoomify Image Folders and PFF files to the ZIF format.

Note regarding local viewing: ZIF files are TIF file containers holding the many small JPEGs that make up a zoomable image and other data. On the web, these JPEGs are downloaded from within the ZIF file using partial file requests - a standard part of the HTTP web protocol. Locally however, these requests are blocked by all browsers to ensure maximum file security.

Instead, requests must be made using file access functions with a higher level of protection. Because of this, when testing a web page on a local machine, a Browse button is displayed and the exact file to view must be selected manually. In addition, the starting directory of the browse feature will not be the current working directory. (On subsequent views of the same page in the same the browser feature may retain the starting directory previously selected.)

See this example in action on the Zoomify website or simply copy this example web page file '13-ZIF-LocalViewing.htm' to your web server along with the zoomable image file ZoomifyImageExample.zif, the viewer file ZoomifyImageViewerExpress-min.js, and the toolbar skin graphics folder Assets/Skins/Default.

Final note for long-time Zoomify customers: this new local viewing support is also available for Zoomify Images stored using the Zoomify PFF format and in addition, the Zoomify Java Servlet is no longer requird for viewing PFF files, whether locally or from a web server.
