Summary0008665: Locale-dependant internal parsers (ej: sscanf/strtod) fails to interpret correctly float fields.
DescriptionSpecifically in vtkDICOMParser, float parsing functions (sscanf) are unable to interpret correctly float values due locale-dependant decimal separator.

This behavior makes DICOMParser to generate a unorderer voxel without measurement and wrong calculations, causing ugly warnings like:

ERROR: In /usr/devel/lib/VTK-5.2.1/Filtering/vtkImageData.cxx, line 1473
vtkImageData (0x4b9e930): GetScalarPointer: Pixel (0, 0, -2147483648) not in memory.
 Current extent= (0, 255, 0, 255, 0, 59)

ERROR: In /usr/devel/lib/VTK-5.2.1/Filtering/vtkImageData.cxx, line 1473
vtkImageData (0x4b9e930): GetScalarPointer: Pixel (0, 0, -2147483648) not in memory.
 Current extent= (0, 255, 0, 255, 0, 59)
Steps To ReproduceCode:

vtkImageData* img = vtkImageData::New();
char *oldLocale = setlocale (LC_NUMERIC, "C");
vtkDICOMImageReader* reader= vtkDICOMImageReader::New();
reader->SetDirectoryName(thePath);
reader->Update();
img->DeepCopy(reader->GetOutput());
setlocale (LC_NUMERIC, old)
viewer->SetImage(img);

Trivial Fix:

vtkImageData* img = vtkImageData::New();
char *oldLocale = setlocale (LC_NUMERIC, "C");
vtkDICOMImageReader* reader= vtkDICOMImageReader::New();
reader->SetDirectoryName(thePath);
reader->Update();
img->DeepCopy(reader->GetOutput());
setlocale (LC_NUMERIC, old)
viewer->SetImage(img);

or launching with LC_NUMERIC setted.

Code to reproduce is obviusly wrong, so LC_NUMERIC should be, by example: es_ES.UTF-8
