This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I have noticed that the local variable "int tmp;" in the methods vtkFreeTypeStringToImage::GetBounds should be initialised to values of 0. Indeed, the later call to GetBoundingBox is not populating that variable when the string is empty.
This manifest it-self on by an empty chart since the calculation of the axis size is completely wrong.
I am seeing this problem on Linux using a quite recent version of vtk trunk linked with Mesa.
