Dear VTK users and developers,
The VTK 5.4.2 patch release is now available for download from the VTK
web site: http://vtk.org/VTK/resources/software.html . A full list of
changes are included at the end of this message.
We hope you enjoy this new release of VTK.
Instead of deleting timers immediately, mark them for deletion next time
the event loop is entered.
When a user transform is applied to vtkAxesActor, make sure the axis
labels are translated with the axes
Fix a memory leak
Bug fixes courtesy of Terry Jordan.
The first set of changes is necessary because for some reason this
reader never supplied ParaView with its number of cells.
The second set of changes is necessary because it seems now that we have
either encounter errant fluent files or an error in their writer or
possibly some change to there file formatting that no longer supplies
the index within the end of binary section entry. This patch is
backwards compatible and has worked on all data sets tested.
Also fix uninitialized this->NumberOfCells. As this is used in
PrintSelf. Detected by valgrind on otherPrint.
*Rendering/vtkCameraActor.cxx & Rendering/vtkLightActor.cxx*
Changed vtkErrorMacro into vtkDebugMacro to avoid printing error in the
context of just creation an object followed by Print(). It happened
because PrintSelf on the actor calls PrintSelf on superclass, which call
GetBounds, which call UpdateViewProps() on the concrete classes
vtkLightActor and vtkCameraActor.
Fix location for mouse events, bug #8261.
Use VTK_LIBRARY_PROPERTIES value for VERDICT_LIBRARY_PROPERTIES. Makes
library VERSION and SOVERSION consistent with other vtk utility
libraries on Linux builds.
Check for a null pointer
*Widgets/vtkLineRepresentation.h & Widgets/vtkLineRepresentation.cxx*
Computation of parameteric coordinate: t and the closest_point was done
in display coordinates. The value t cannot directly be mapped to word
coordinates, since it needs to be scaled according to the projection
matrix. (The farther you go from the camera position, the larger the
increments in t). To avoid this, keep everything in word coordinates by
using a picker.
