[Insight-users] Re: Resizing an Image

[Balaji Gandhi]

Hi Luis/All,

I am using the original source code provided in the
Insight/Examples/Filtering and Insight/Examples/Registration to read the (16
bit/Gray Scale) images. What is the PixelType for reading and writing 16
bit/Gray Scale Images? Please advise.

Thanks,
Balaji
