The requesting library views the HTML-ised email message through its browser, and selects the link to the image which will launch the appropriate viewer for that image. The image can then be printed. As a housekeeping measure, a background process monitors the access log for the process and deletes image files that have been accessed. The length of time before this deletion occurred could be parameterised to suit individual libraries. What's new with REDD REDD is no longer a project, but a fully operational service.
Enhancements continue to be made to the software.
For release in the near future will be an option to provide virtual desktop delivery to users. A page giving details of the transaction will be added to the TIFF file by creating a Visual Basic CGI script using the Wang Imaging for Windows 95 OLE custom controls. The CGI script will then email the MIME encoded TIFF file to the requesting library. The user locates the Web file, copies or prints the file. A monitoring programme deletes the file once the user has located it.
