| Summary | 0000558: vtkCaptionActor2D with border | ||||||||
| Description | Hi all, ************************************************* After adding a viewport to a renderer and using vtkCaptionActor2D with border, I have noticed that the border is drawn with an offset. Is there a way to change this ? ************************************************* You can find my materials from: http://dods.ipsl.jussieu.fr/brocksce/vtk_pb03 [^] Edit TestCaptionActor.tcl and uncomment line 48 #ren1 SetViewport 0.2 0.2 0.8 0.8 Will produce caption_2.png image. Without any change the script produces caption_1.png Hope that someone could help on this. | ||||||||

I think this bug is due to the fact that in vtkCaptionActor2D the position of the caption is computed in display coordinates, and these are used for the points in BorderPolyData. vtkPolyDataMapper2D, however, expects the points to be in viewport coordinates. The solution to this (I haven't tried it) is to use a vtkCoordinate, that will transform from display to viewport coordinates, and set it in BorderMapper (by calling SetTransformCoordinate()) in vtkCaptionActor2D::New(). Another approach is to get viewport coordinates when setting the points of BorderPolyData in RenderOpaqueGeometry(). Note: The documentation of PolyDataMapper2D is misleading, as it uses the term 'local display coordinates' for what are actually viewport coordinates. |

I uploaded a patch for this bug. This is a patch against rev. 1.23 of vtkCaptionActor2D.cxx (the latest on the 4.2 branch). It can however be applied to rev. 1.27 and 1.28 too (the latest on the 4.2 branch and on the main trunk at this moment). See my previous comment for an explanation of the fix. |
