I noticed this behavior with the new default Rendering Mode preference set to 1 instead of 0, which does map to anti-aliased rendering. However, when starting the MITK Workbench clean, rendering is done without anti-aliasing. Opening the preference page containing the Rendering Mode preference does show anti-aliasing in its combobox. Without changing anything, press Okay and restart the MITK Workbench. Anti-aliasing is working now. This is because the prefs.xml file created by the MITK Workbench on a clean start does only contain a few preferences:
<preferences name=""> <property name="showIntro" value="false"/> <preferences name="qtstyles"/> <preferences name="org.mitk.core.ext.preferences.inputdevices"/> <preferences name="org.mitk.views.datamanager"/> <preferences name="org.mitk.editors.stdmultiwidget"> <property name="widget1 corner annotation" value="Axial"/> <property name="widget2 corner annotation" value="Sagittal"/> <property name="widget2 second background color" value="#000000"/> <property name="widget1 second background color" value="#000000"/> <property name="widget4 corner annotation" value="3D"/> <property name="widget2 decoration color" value="#00b000"/> <property name="widget4 decoration color" value="#ffff00"/> <property name="widget1 first background color" value="#000000"/> <property name="widget3 first background color" value="#000000"/> <property name="widget3 corner annotation" value="Coronal"/> <property name="widget3 decoration color" value="#0080ff"/> <property name="widget3 second background color" value="#000000"/> <property name="widget1 decoration color" value="#c00000"/> <property name="widget2 first background color" value="#000000"/> <property name="widget4 second background color" value="#7f7f7f"/> <property name="widget4 first background color" value="#191919"/> </preferences> <preferences name="org.mitk.views.imagenavigator"/> <preferences name="General"/> </preferences>
After the steps described above, the file looks like this, though, now containing the missing preference, resulting in anti-aliased rendering after restart:
<preferences name=""> <property name="showIntro" value="false"/> <preferences name="qtstyles"/> <preferences name="org.mitk.core.ext.preferences.inputdevices"/> <preferences name="org.mitk.views.datamanager"> <property name="Show helper objects" value="false"/> <property name="Allow changing of parent node" value="false"/> <property name="Show nodes containing no data" value="false"/> <property name="Place new nodes on top" value="true"/> <property name="Call global reinit if node is added" value="true"/> <property name="Call global reinit if node visibility is changed" value="false"/> <property name="Single click property editing" value="true"/> <property name="Call global reinit if node is deleted" value="true"/> <property name="Use surface decimation" value="true"/> </preferences> <preferences name="org.mitk.editors.stdmultiwidget"> <property name="widget2 second background color" value="#000000"/> <property name="widget4 first background color" value="#191919"/> <property name="crosshair gap size" value="32"/> <property name="PACS like mouse interaction" value="false"/> <property name="widget3 decoration color" value="#0080ff"/> <property name="widget3 first background color" value="#000000"/> <property name="Show level/window widget" value="true"/> <property name="widget2 decoration color" value="#00b000"/> <property name="widget1 first background color" value="#000000"/> <property name="widget3 corner annotation" value="Coronal"/> <property name="widget2 corner annotation" value="Sagittal"/> <property name="Use constrained zooming and panning" value="true"/> <property name="widget1 decoration color" value="#c00000"/> <property name="widget1 second background color" value="#000000"/> <property name="widget4 corner annotation" value="3D"/> <property name="widget4 second background color" value="#7f7f7f"/> <property name="widget2 first background color" value="#000000"/> <property name="Rendering Mode" value="1"/> <property name="widget4 decoration color" value="#ffff00"/> <property name="widget3 second background color" value="#000000"/> <property name="widget1 corner annotation" value="Axial"/> </preferences> <preferences name="org.mitk.views.imagenavigator"/> <preferences name="General"> <property name="LastFileOpenPath" value="C:/Users/kislinsk/Desktop/test.mitk"/> </preferences> </preferences>
