When using Delft-FEWS the configuration can be present as files on the file system or can be contained in a local data store. The svg files that are used for the scada display work in both cases. However, if the svg files refer to separate image files, then the scada display can only display these images if the image files are present as files on the file system. If these separate image files are contained in a local data store, then they cannot be displayed in the scada display. Therefore, when using separate image files, make sure that the configuration is present as files on the file system. If this is not possible, then the best it is possible to choose from two different workarounds:
- The first possible workaround is to not use separate image files. For a schematic image it is possible to create svg elements that resemble the contents of the image. If these svg elements are added to the svg file for the scada display, then there is no need to use the image file anymore.
- The second possible workaround is to use embedded images instead of separate image files. The section Embedding image files into SVG files describes how to do this.
