Hi,<div><br></div><div>I'm developing with ITK 3.20 + GDCM 2.0.17 + VTK 5.6 and I've noticed itkImageSeriesReader is ~2x slower than vtkGDCMImageReader (from GDCM2). I compared both codes and I think the difference is the extra copy which itkImageSeriesReader makes from ImageFileReader's output to its own output (ImageSeriesReader::GenerateData() line 393). I've commented it just to test the time needed without making the copy and now both readers take more or less the same time.</div>
<div><br></div><div>Is there a way to avoid the copy? I mean, could ImageFileReader write into the itkImageSeriesReader's output allocated memory directly?</div><div><br></div><div>I've also attached a test program if someone want to test it.</div>
<div><br></div><div>Thanks for your attention,</div><div><br></div><div>Roger</div>
