MeVisLab Release Notes before 4.0

Python site-packages in MeVisLab user packages were not signed for add-on installers.

The necessary OpenCV libraries were not added automatically to installer when using the VideoWriterML or VideoWriterInventor modules.

Windows: Fixed calling "Dependencies" tool in the DynamicDependencyAnalyzer.

Linux: The OUTPUT_PYTHON_EXE variable wasn't set correctly.

The WebEngineView control gained the ability to print the current web page. (Set the enablePrinting attribute to get the context menu entry!)

Expanded the TestWebEngineView example module with a demo for embedding of Inventor viewers. Added a special RemoteRendering scripting wrapper for this.

This is not as smooth as with the old WebView control though.

Also added a removeObjectFromWebChannel method to the MLABWebEngineViewControl wrapper, so that objects can be deregistered again.

Updated bzip2 to version 1.0.8.

Added XZ Utils (specifically the liblzma part), version 5.2.5.

Fixed handling of the -runapp argument with the MeVisLab executable for users with the necessary license features.

Can override the execution level for NSIS (Windows) installers by setting INSTALLER_NSIS_EXECUTION_LEVEL to the desired value.

Can change the name used for registry values, preferences file, etc. without changing the application macro name by setting STANDALONE_APPNAME in addition to STANDALONE_MACRONAME.

Fixed ZIP compression failing if files have a modification date before 01-01-1980.

Documentation: Added a section about recognized values in mevislab.prefs and possible environment variables to the MeVisLab Reference Manual.

You can provide a PreloadModule tag in your preferences file to preload custom modules in your IDE. This feature is meant to allow customization of the IDE (e.g. to set a variable to a file path that should be determined at runtime).

Where available we now use the SPDX license identifiers (from https://spdx.org/licenses) for third-party libraries in the about dialog.

Pressing the space bar in the network view of the IDE toggles to/from the special view, where previously you needed to hold the key to get it (which prevented tool tips from appearing).

Added the preferences variable disableImmediateDebugOutputConsoleRefresh which can be added to the preferences file to disable immediate console outputs, which can be slow and have unwanted side effects.

Fixed non-integer GUI scaling factors set with the environment variable QT_SCALE_FACTOR.

Added a keyboard shortcut Ctrl+F5 for running the selected test in the TestCaseManager (available on Windows and Linux).

Clear list of test functions if no test case is selected.

Ensure that tests started from a module's context menu and from the TestCaseManager do not interfere with each other.

Added tooltip to Python coverage check box (if checked) that Python Coverage might list additional Python modules.

One can set the expected outer scope for MDL include files (which helps MATE with auto-completion) by adding a comment line // mdl-validator: ValidatorScope, for example: // mdl-validator: Window.

Improved the file search in the project workspace.

Some improvements/fixes for the Find In Files dialog.

Added basic support for QML files, the GUI description language of Qt.

Removed some global button mask enums from SoManagedInteraction.

Do not crash when using a diamond shaped network pattern with automatic updates that leads to invalid image page accesses.

Field control: Make hintText attribute work if comboBox = Yes and edit = Yes.

ListView control: Do not change column resize mode on hide/show of column.

Can select horizontal tabbing when editing cells in the ListView and ItemModelView controls with the tabDirection attribute.

If a control implemented with a Python class has the method controlDestroyed it will be called when the control's destructor is called.

The QWidget.fontInfo() and QWidget.fontMetrics() methods didn't work in PythonQt.

MLABWebEngineViewControl now has a method setWebPage to set an own QWebEnginePage instance.

Warn about unknown variables in MLAB.replaceMDLVariables.

Added a method qmlModel() to the MLAbstractItemModelWrapper which returns a model suitable for use in the QuickView control. Also added usage examples in the TestQuickView example module.

MeVisLab has a changed logo, new icons and splash screens.

Updated libjpeg to version 9d (Note: May return slightly different pixel values when loading jpeg files now)

Updated libjpeg-turbo to version 2.0.4.

Updated libtiff to version 4.1.0.

Updated sqlite3 to version 3.32.3.

Updated CryptoPP to version 8.2.0.

Updated OpenSSL to version 1.1.1g.

Updated TBB (Threading Building Blocks) to version 2019 U1.

Python

Added new zoom modes VIEW2D_FIXED_PIXELS_PER_VOXEL_X_SCALED_FOR_HIDPI, VIEW2D_FIXED_PIXELS_PER_VOXEL_Y_SCALED_FOR_HIDPI, and VIEW2D_FIXED_PIXELS_PER_MM_SCALED_FOR_HIDPI that scale the zoom value with GLHiDPIScale.

Fixed SoView2DVoxelValue behavior in SoOrthoView2D when not using Managed Interaction mode (no value was shown in two of the three views).

Fixed a crash in SoView2D when building the look-up-table for too large min/max value ranges.

One can now use the #version directive in SoGVRShaderFunction.

SoViewportRegion got more display options and can use a Python callback for calculation of position and size of the viewport. See the "Details" section of the module's help for how to do this.

Removed the broken AutoUpdateColors mode from the SoPathTracerMesh module.

CSOLabelPlacementGlobal: Added start and end angles for label placement.

CSOLabelPlacementGlobal: Added a CSOList input that can be used as label placement boundary.

SoCSOLabelRenderer: Do not move explicitly placed labels when tryToPlaceLabelsWithoutOverlap is set.

WEMExtrudeCSO: Fixed error handling.

WEMExtrudeCSO: Added new extrusion mode RELATIVE_TIMES_DIRECTION.

Fixed a crash in DicomFrameSelect if no frame-specific information was available.

Arithmetic1: Fixed handling of min/max value for values smaller than zero.

Exported helper classes from the MLOpenCVModules library for use with own OpenCV modules.

CalculateGradient: Fixed min/max value range calculation.

Window: Can handle negative image values now.

RemotePanelRendering: Can now limit the number of modules that can use the GPU at a time with the environment variable MLAB_NUMBER_CONCURRENT_PANEL_RENDERING to avoid a possible bottleneck with graphics drivers.

Tried to make the module panels of XMarkerListContainer and StringListContainer clearer.

The OpenCVUtils Python module has been moved from package FMEwork/ReleaseMeVis to MeVisLab/Standard.

One can now promote a local macro to a global macro from the context menu of the module.

Fields of imported panels in the GUI only allow dragging to/from other fields now if they are exported as internalName on the module of the window.

Closing the IDE will now also close all module panels (if MeVisLab should be terminated).

Prevent recursive reloading of modules while pressing and holding F5 key.

Fixed 'object' not working in console of the PythonObjectInspector - it's '_object' now.

Ask the user if the debugger should be disabled if Python coverage is activated (since only one of these can work at a time).

Function parameters can now be passed as dicts (keyword arguments instead of position arguments) to iterative tests in a test case.

Improved error handling for secure testing mode.

The tearDownTestCase() function is also called for cancelled tests now.

MATE got a dark mode on Windows and Linux (available from the Preferences panel).

Added support for mypy besides Pylint (not simultaneously though).

Update default Pylint version to install to 2.4.1. Also added inference limit config value, which can improve performance when set to a lower value.

For modules with several scripting source files, Pylint (or mypy) is applied to the combined source to improve the output - note that this is only detected if there is an associated module in a connected MeVisLab instance.

The Watch area in the Python debugger got a context menu command to remove all watches at once.

Improve the behavior of the Python debugger if accessing object attributes to display them in the debugger causes Python exceptions.

Added method CSOGeometry::computeClosestPathPoint which really returns the nearest path point of a CSO.

Added a tooltipField attribute to all controls, which allows to set the tool-tip of a control through a field.

Fixed initial visibility of buttons using the visibleOn attribute in a ButtonBox control.

Fixed sorting in ListView control if initial item values are changed later on.

Users can now add a custom entry to the context menu of modules. Just add a .def file with a ModuleAction to your package, which should have a title, condition (a short Python expression) and a userScript attribute. Have a look at the ModuleAction in Packages/MeVisLab/Standard/Modules/Macros/Wizards/LocalToGlobalUserScript/LocalToGlobal.def for an example.

Added method enableAlternatingRowColors to the MLABListViewControl.

Added method setAllowRenaming to the MLABIconViewControl.

Added deepCopy method to the CSOList scripting wrapper.

Fixed MeVisLab hanging when using keyword arguments on a slot that didn't have the kwargs parameter.

Fixed the requestStopProcessing call on remote modules to not apply to anything that is sent to the remote module after this call.

Changed output of MLAB.detailedSystemId() and MLAB.systemInfo() (at least on some platforms). MLAB.detailedSystemId() is deprecated now, since it actually isn't very detailed. We recommend to use PythonQt.QtCore.QSysInfo instead.

One can now set the variable ProfilingTraceFile in the preferences file to employ the profiler from the start to debug startup problems.

Added a -printJSONInfo option to the MeVisLabPackageScanner.

Updated Qt to version 5.12.6.

Updated fontconfig to version 2.13.1.

Updated libzeromq to version 4.3.2.

SoView2DLabel: Can set margin to background borders.

SoView2DOverlayDecoration got an option to draw the border outside the image.

Added the updateLayout method to the SoView2D scripting wrapper to update the viewer layout manually.

Make SoMouseGrabber switchable to Managed Interaction, and use that feature accordingly in InteractiveRampLUT and View2D.

The SoXxxxMenu menu widgets got a field to control the factor for darkening/brightening on mouse-over.

Added support for IBL_Equirectangular projection to SoPathTracerBackgroundLight (automatically detected from input image).

Added filled rectangle, filled circle, and filled triangle to seed point styles.

Seed points now scale with the line thickness.

Improved interactive movement of labels.

Added new flag restrictToImageBoundaries on SoCSOPointEditor.

Improved the WEM output inspector.

One can select a simple sub-division mode in WEMSubdivide now.

Fixed that PVL values were doubled in any WEMProcessor module.

Added a bunch of graph editing modules:

Resample3D: Ensure that the output size is at least 1 in each dimension.

VoxelizeInventorSceneGPU works on Radeon cards now.

SoImageFileSampler: Added options to generate seamless and Mip-mapped textures.

Added the DicomDeidentify module for anonymization of DICOM data.

Fixed handling of WindowCenter and WindowWidth for VOI LUT Function "LINEAR" in DicomLUT and RampLUT modules - note: this needs to be enabled in existing networks.

LUTCombiner now allows scaling of the input LUTs.

DicomTool does not write multi-frame information to the individual slices it saves anymore.

Single files listed in the Deployment section of modules do not cause further dependency analysis.

Global modules don't have precedence over local macros anymore. Only if no local macro with the given name exists a global macro with the same name is used (and vice versa).

One can disable persistence of module panel positions and panel state by setting the DisableModuleWindowsPersistence variable in the preferences file. This helps avoid unnecessary differences in version control systems.

Only print package dependency warnings when loading networks in the IDE.

Longer enum value lists in the HTML help of a module get a scrollbar.

The automatic panel of modules can be opened with Alt+[Shift|Control]+double click and Alt+Enter.

Added the facility to display modules with a custom icon (per module type) from a user script that can be selected in the Preferences dialog.

Fixed Python debugger updating local variables too late when function locals() (or something similar) is used in code.

Automatic reload of modules on double-click also considers changed MDL includes now.

Allow to run GoogleTest tests from a FunctionalTestCase. Example (to be put into a TestCase's python file:

from TestSupport import CodeTest
CodeTest.inject("$(MLAB_MeVisLab_Standard)/CodeTests/bin/MLBaseTest", ctx)

TestCases can decide to display the used sorting literals in the TestCaseManager (by setting showTestFunctionSortingLiterals in the .def file).

When typing in the filter line of the TestCaseManager, up and down keys change the selected visible test.

You can tell a test to use software rendering with the new keyword preferredRenderer=software (in the .def file of the test) when using secure testing (only on Windows, and on Linux when using the Mesa graphics driver).

Tests are by default always run with Secure testing if the environment variable MLAB_USE_SECURE_TESTING_BY_DEFAULT is set.

Module help screenshots made on HiDPI screens are now scaled down automatically.

Make dot color (when visible whitespace option is active) configurable.

Made the Pylint timeout configurable.

Added new keyboard shortcut Ctrl+F3 to find the selected text.

Closed documents can be removed from the document session now.

Python syntax highlighting in MATE is now more exact with string and number literals. (Did you know that 1.3j is an imaginary number in Python?)

One can define and run custom commands from the project workspace context menu now.

Fixed and extended Go Back/Go Forward functionality. It now more closely resembles the functionality you may know from, e.g., Visual Studio.

Toggling between .script and .py file (default binding is Alt+Down) usually also works now if not connected to a module instance in MeVisLab.

The SoPointingAction class can now declare it doesn't want dragMoveTo calls for mouse clicks, even if the mouse was slightly moved during the click.

SoDiagram2DExtensions now have more options in which layer to draw.

The AdjustDimInfo<> template was moved from the code of the SubImage module to the MLTools library.

Introduced a new ml::OpenGL::getVideoMemorySizeInMB() method which is smarter about returning the texture/video memory actually available in OpenGL.

Implemented the Base::deepCopy method on BaseList (and XMarkerList).

View2DSliceList::getSliceNormal() always returns the real slice normal (and not just the z vector) now.

The SoFieldData::getRemovedFieldNames() method of Inventor nodes is evaluated in MeVisLab now.

Added the WebEngineView control, which is similar to the WebView control, but uses the QtWebEngine widget based on Chromium instead of the outdated QtWebKit widget. The new control doesn't allow access to modules, scripting, or module panels of MeVisLab, since the browser engine runs in a separate process, but since the old widget isn't supported anymore we will need to remove the old one in one of the next versions and therefore we urge you to switch if you currently use WebView.

The expandY attribute of most controls defaults to auto instead of no now, so you now should rarely need to set this yourself.

Added a validator tag to the ComboBox control, which takes a regular expression against which to check the input of an editable ComboBox.

Added a insertSeparator method to the ComboBox script wrapper.

Added methods setModulePanel and setModuleWindow to the DynamicFrame control.

Implemented auto-indentation for the PythonTextView control.

Added support for direct texture transfer between processes in RemoteRendering (only on Windows, and on the same computer). Set the useDX11SharedTexture attribute on the RemoteRendering control to activate.

Added popupMode = [Instant|Delayed|MenuButton] support to the ToolButton control.

Added titleField support to the ToolButton control.

Added the acceptWheelEvents tag to some controls — default is true.

Added the tag comboEditable to the Field control.

Added a componentTitles attribute for Field and VectorEdit controls, and setComponentTitles and setComponentTitleAt scripting methods, which allow to override the default component titles of a vector edit control.

Fixed initial visibleOn state of panels included with the Panel control.

Added visibleOn expressions for MenuItem entries.

visibleOn expressions on controls are evaluated delayed to fix panel layouts growing in size in some situations. This could happen when an intermediate state was used for size calculation where widgets were temporarily visible together that were actually never shown together in practice.

Fixed layout flickering on Label controls with a frame and trimming enabled.

Added a windowActivatedCommand to the Window control.

The ListBox scripting wrapper got a sort method.

When calling unknown methods on objects derived from QWidget a hint is printed that the user perhaps needs to do from PythonQt import QtGui first.

We enabled multi-threading in Python. In case of problems you can disable it with an entry PythonMultiThreading = NO in your preferences file.

Added MLABModule::callOnGUIThread scripting method to call a scripting function from any thread.

The Qt scripting bindings were updated for version 5.12.

Added an MLABSoPathField class which allows to access the Inventor node path result of (currently only) module SoPicking from scripting.

Removed the method MLAB.macRunPrivilegedCommand.

Removed the method MLAB.gpuTextureMemoryInMB, rather use MLAB.gpuVideoMemoryInMB.

MLABImageField.mapVoxelToWorld and .mapWorldToVoxel scripting methods also work on the Inventor SbVec3d class now.

Added scripting methods for adding and removing vessel voxels to the ml::Graph scripting wrapper.

Moved method MLAB.priv().aboutThirdPartyHTML() to MLAB.aboutThirdPartyHTML().

The arguments to OpenVDBGridWrapper::toWEM were switched around. If you used this, please adapt your code.

Added a new scripting wrapper that allows to find the real nearest point of a WEM triangle mesh (and not just the nearest node of the mesh). Obtain this wrapper with wem.createNearestPointOnSurfaceObject().

Fixed that WEMWrapper::removeWEMPatchAt took the argument as id of the WEM instead of as index. Also added WEMWrapper::removeWEMPatchById.

Added support for async Python functions in MeVisLab in general and in field listeners and test functions in particular.

Added a script wrapper for the MLABRecentFilesHandler, accessible with MLAB.createRecentFilesHandler.

Added the MLABTreeWrapper::deepCopy() scripting method.

Added scripting method MLABPackageManager.getMeVisPythonExecutable which returns the location of our Python interpreter executable.

Added the getTransform method to the scripting wrappers of SbMatrix and SbMatrixd.

MeVisLab now changes the PATH on Windows in a way that this change is also visible from Python in os.environ. This fixes that augmenting the PATH from Python would overwrite the changes from MeVisLab, which prevented loading of modules, e.g., after installing and using an externally installed NumPy.

We changed our policy on unlicensed use: An unlicensed MeVisLab SDK treats modules signed by non-MeVis owners as unlicensed now.

Fixed an issue with too long filenames generated in the Python coverage detection of the TestCenter.

Fixed that links to overview documents could not have a different title in mhelp files.

DICOM image loading duplicates the value of the PixelSpacing or ImagePixelSpacing tag when this tag only contains one value (thus fixing invalid DICOM files).

Project wizards can have a condition (a Python expression) which defines if the wizard should be shown.

Make module dependency analyzer detect DLLs from scripting wrappers.

Added some DicomTree error logging.

Updated Qt to version 5.12.3.

SoView2DRigidRegistrationEditor: Added an alpha field and a trigger to reset the rotation center, also made rendering of shadow optional.

Fix arrow lines not showing in SoView2DMarkerEditor in certain corner cases.

Multiple SoRenderSurfaceIntersection modules share the same buffers now and the buffers are only resized if necessary.

Added the option Only render opaque objects to the SoPostEffectMainGeometry module.

The View3D module can be switched to RayCaster mode now.

Improved multi-core and hyper-threading usage of GVR framework, switched to using OpenMP.

Extended SoMarkerListPointSet and So3DMarkerEditor to allow filtering XMarkers by timepoints.

Added a new SoCameraWidget module for moving the Inventor camera from a widget.

Added new SoSlideWidget module similar to SoCameraWidget, intended for touch navigation in viewers.

SoPicking got a highlighted output flag and can provide two extra pointing actions (because sharing the same sub-scene between different SoPicking modules does not work).

SoPicking allows to get the picked color now.

Implemented an update mode for the SoSceneLoader module.

The AnimatationRecorder has been improved.

Removed the font field from SoExtText2, added a fontSize field instead, did the same for So3DXMarker and So3DMarkerEditor.

Fixed finding of a starting position for polygonization in WEMVascularSystem.

Added support for FloatPixelData DICOM tag to ImageSave and ImageLoad.

ImageSave can't save RGBA images in DICOM mode anymore, this wasn't done correctly anyway.

Added option to only render vessel voxels to the output image of the GraphToVolume module.

RemotePanelRendering can render modules in parent networks now (by specifying the "parent:" prefix), not just sibling modules.

Fixed some mouse coordinate offset problems with RemotePanelRendering.

Added new error handling mode ExactlyOneOpenInputIsError to the ImageCompare module.

One can now specify the page extent for the ImageCompose module (and for the VirtualVolume class).

3D inspectors can zoom with the mouse wheel.

Prepend "./" to the displayed type of local macro modules.

The Run In Separate Process context menu entry shows a hint why it is disabled when it is disabled.

Connecting fields by dragging fields to the automatic panel was not undoable and also didn't mark the network as modified.

The MeVisLab Output Inspector now supports specialized inspectors for Python object sub-types.

Print an error message if a FieldListener has no field or no command given.

Fixed CTRL+Tab switching between networks in IDE and files in MATE.

Fixed inheriting module documentation if the module name is not the class name.

Can avoid per-function result directory by setting perFunctionResultDirectory to False in the .def file of the test.

Added option to display test report viewer inside the main TestCaseManager panel.

Newly opened MATE documents are inserted after the tab from which they were opened.

The replace-in-files dialog always writes system-specific line endings now.

Added new ML list fields: ml::IntListField, ml::DoubleListField, ml::Vector2ListField, ml::Vector3ListField, and ml::Vector4ListField (similar to the Inventor multi-fields).

The mlError, mlWarning, mlInfo macros do not need an error type argument anymore. If omitted, ML_BAD_PARAMETER is used.

ml::Fields don't have a copy constructor anymore.

Added new getInterpolatedValue() method on ml::PagedImage which allows to fetch a tri-linear interpolated value at an arbitrary location.

ml::Rotation now creates a 180° rotation for exactly opposite vectors (previously it did nothing).

The Inventor class SoEvent now has a mouseButtonMask property that contains the currently pressed mouse buttons.

Allow to override existing cursor shapes in Inventor viewers with SoViewerProxy::defineCursor.

Added a BLANK_CURSOR value for the cursor shape enum field in Inventor modules.

Renamed internal Inventor class SoLightPath to SoLightweightPath because the name was confusing.

The destructor of Inventor class SbProjector was made virtual.

Added a ML_EXPLICIT_FALLTHROUGH define to all platforms, which expands to [[fallthrough]] (C++17) on platforms where an implicit fallthrough would result in a warning at compile time.

Added new method ml::OpenGL::isMesaSoftwareRenderer() to check if MeVisLab runs with an OpenGL software renderer.

Added a PythonTextView control for editing Python code in modules. It supports auto-completion of the underlying module context, context sensitive help and an extended context menu. Many modules that offer Python scripting now make use of this control (RunPythonScript, PythonArithmetic, ...).

ItemModelView can show a color and a checkbox in the same column.

Implemented an alternatingRowColors attribute on ItemModelView.

Added alternateBase (needed for alternatingRowColors), toolTipBase, and toolTipText color roles to MDL style.

Added clickedColumnField attribute to ItemModelView control, which writes the column index onto which the user (double-)clicked to the given field.

Introduced ComputedAttribute to ItemModelView control. This allows to compute a virtual attribute from other attributes using the same expression parser as, e.g., the dependsOn mechanism.

Implemented dependsOn/visibleOn on the Row element of the Table control.

Added new listview mode on TabView control. This facilitates the creation of preferences-style panel with a listview instead of a tabbar to select tabs. The listview can be made hierarchical by using the tabHierarchy tag on TabViewItems.

Fixed initial enabled state of TabView with only one child.

Fixed that dependsOn of ButtonGroupControl items always affected the first item.

When a parent checkbox in an ItemModelView control switches several child checkboxes, these are collected into one ItemModel update event.

Removed slicerScale attribute on Slider control (it didn't work anyway).

The Space key is not titled "Any" anymore in the EventFilter control. Also added the numerical "keyCode" info.

Call shouldCloseCommand if a modal dialog panel is closed with the Escape key.

Use system proxy settings by default in WebView control if no proxy is specified in the Preferences dialog of MeVisLab.

The Field control now recognizes the comboItems attribute.

Fixed wrong auto-alignment groups on the Grid control. Previously all Grid children got the same width, regardless of their column.

The More button on a Field control now shows a non-editable dialog if the control is non-editable.

Fixed problem with auto-repeat in step-buttons of number widget if a dialog is opened on value change.

New field wrapper classes for the ML list fields and some Inventor multi-fields: MLABIntegerListField, MLABDoubleListField, MLABVector2ListField, MLABVector3ListField, and MLABVector4ListField.

Since previously these fields were wrapped with MLABStringField you will now get an info message if you use the old value property which has a string type. You should rather use the new listValue property or stringValue()/setStringValue().

Added mlab_projects Python meta package for importing Python modules from MeVisLab module projects. (Not supported in auto-completion!)

Use

from mlab_projects.MySuperDuperProject import Utilities

Added MLAB.cryptStringUTF8()/MLAB.decryptStringUTF8() scripting methods with UTF-8 support.

Added setVr method to MLABMutableDicomTag.

Python object __object__ in the module context can now be any Python object to be visible through ctx.object(). Previously the auto-conversion of Python sequences or maps caused a conversion to a different object type.

The field associated with a control can now be accessed with the field() method.

MLABProcess.runCommandInConsole now has an option to wait until finished.

Added new scripting methods on macro modules to determine the sub-type (local, ad-hoc).
