Summary0013218: vtkTextActor will render very tiny wrong block if empty string/space is set as the input
DescriptionDetected this issue in VTK 5.10, i guess it is old issue related to 0010905
When empty string("")/space(" ") is set as vtkTextActor Input, got some error report as "No scalar values found for texture input!" from vtkOpenGLTexture.
I discovered there is some tiny block rendered on the screen.

I think the simple fix is not render vtkTextActor if Texture input data is empty(0).
Maybe better approach is correct some image data in vtkFreeTypeUtilities.
TagsNo tags attached.

 This bug is no longer present since the switch to vtkFreeTypeTools/vtkTextRenderer.
