[Insight-users] Problem on running HoughTransform2DLinesImageFilter.exe (ERROR: PNGImageIO)

[Tatiana Al-Chueyr Pereira Martins]

Hi everyone,

I'm newbie to itk. I couldn`t find any related error/problem on google, so I
decided posting my problem.. Hope someone might help.

While running *.exe examples generated for testing itk, I managed to run
several examples successfully (such as FourierDescriptor1.exe)  but when I
tried to run HoughTransform2DLinesImageFilter.exe using
HoughTransformTwoLines.png, teste.png and 2 as params, I got the following
error:

<ERROR MSG>

C:\Insight_bin\bin\Release>HoughTransform2DLinesImageFilter.exe../../../Insight/Examples/Data/HoughTransformTwoLines.png
teste.png 2
Applying gradient magnitude filter
Thresholding
Computing Hough Map
Found 2 line(s).
Exception caught !

itk::ExceptionObject (010FF894)
Location: "unknown"
File: C:\Insight\Code\IO\itkImageIOBase.cxx
Line: 361
Description: itk::ERROR: PNGImageIO(015DE250): Pixel type currently not
supported. typeid.name = unsigned char

</ERROR MSG>

Does anyone knows why this error is occuring?

Currently using...
 --------------------------------------
Windows XP Professional
ITK 2.8
CMake 2.4
Visual C++ 6.0
------------------------------------

Thanks in advance,

Tatiana
