[Insight-users] What does this error mean?

[Bill Oliver]

Thanks for the reply, but that doesn't do the trick.

I tried it both ways.

I get the same error:


% ./PNGImageReadWrite /home/oliver/p1sm.png 1 tst.png
File succesfully read !
Exception caught during PNG file writing

itk::ExceptionObject (0x8085550)
Location: "Unknown"
File: /usr/local/include/InsightToolkit/IO/itkImageFileWriter.txx
Line: 119
Description: itk::ERROR: ImageFileWriter(0x8082b40): No ImageIO set, or none could be created.
