Summary

0002945: DICOMImage reader has inappropriate buffer size

Description

I modified the MFC SDI example to show a single DICOM file.

When the window size is small (h<512), and the DICOM file is 512*512, it blows up at the following code in vtkDICOMImageReader: for (int i=0; i < this->AppHelper->GetHeight(); ++i)
      {
      memcpy(b, iData, rowLength);
      b += rowLength;
      iData -= rowLength;
      }

This code is to reverse the image data so that it is compatible with VTK.

The essential reason of the problem seems to be that the following code allocates buffer (*b) size by the size of displaying window.

Line #280 void* buffer = data->GetScalarPointer();
