The user can - then click on an image file in this window to fetch an image. - - IMPORTANT NOTE: If the URL points to a directory, the directory must - not contain an "index.html" file!

Note that saving/uploading a - file can take a while depending upon the size of the image. This is - because, the tool first generates the GIF format and then sends the - bytes across the network. - - IMPORTANT NOTE: The Web server must support image uploading, that is - HTTP PUT functionality.

Note that the effects of any - filters that were applied to the image will be lost. - -o Reload Filters - - Reads the filter configuration file again and reloads all the image - filters. Note that this serves as the trigger of the Service - Configurator pattern allowing the tool to reconfigure based on new - configuration information. - - The filters are specified in filter.conf. To add/remove filters, - change this file and then select "Reload Filters". - - To specify a different configuration file, please see "Getting Started". - -o Zoom In - - Zooms in to the currently displayed image. Note that the applet only - allows to zoom in 4 x times. - -o Zoom Out - - Zooms out of the currently displayed image. Note that the applet - only allows to zoom out 1/4 x times. - -o Apply - - Apply the currently selected filter. By default no filter is - selected.
