[Insight-users] Re: itkimagt to vtkimage?: No BMP reader in ITK

[Luis Ibanez]

Hi Zhao,

ITK doesn't have a BMP reader at this point.

You may try converting this BMP image to a
format like PNG, for which ITK has readers.

A good set of tools for performing such
conversions is available in ImageMagick.

You can download it for free from

      http://www.imagemagick.org/


You could also use the VTK BMP reader in
order to bring the image into memory,
then use the VTKImageToImage adaptor in
order to convert the vtkImageData into
an itk::Image.

Please take a look at
http://www.vtk.org/doc/nightly/html/classvtkBMPReader.html



Regards,


    Luis
