Why is the Weasis license Eclipse Public License?
EPL is more business-friendly about some patent retaliation and reverse engineering clauses than LGPL. With EPL, derivative work (weasis plugin) can be distributed in any license type: open source, freeware, commercial… However, if you distribute Weasis with some modifications (changing existing source code of the open source Weasis plug-ins), even if it is a free distribution, you are obligated to make your modifications available to others.
For more information about EPL, check out the EPL 2 FAQ.
Note that since version 3.7.0 the source code is released in dual license mode (EPL-2.0 OR Apache-2.0). This allows the user to choose one of these two licenses.
Can Weasis be incorporated in DICOM CDs or other removable media?
Yes, Weasis can be embedded in a DICOM CD but only on Windows. On other platforms it is possible to create a DCOM CD but without the viewer. See DICOM Export CD/DVD Image.
How to enable Weasis logging?
The rolling log system must be enabled in the preferences to trace all Weasis activities. For more details, see How to configure and view log files.
Is it possible to download DICOM files without having a WADO server?
Yes, but a WADO server is recommended. Downloading DICOMs can be achieved by:
