[Insight-users] Filters Input Image Pixel Type

[Mauro Maiorca]

Hi Elena,

have a look at the ITK software guide (
http://www.itk.org/ItkSoftwareGuide.pdf), chapter 4 (User's guide -> Data
Representation -> Image), it might answer your question.

Section 4.1.1 shows how to create a 3D image with unsigned short pixel
data, in summary you have to define your image type as:
typedef itk::Image< unsigned short, 3 > ImageType;
If you want to create an image with unsigned int pixel data, you have to
replace "unsigned short" with "unsigned int", i.e.
typedef itk::Image< unsigned int, 3 > ImageType;

You can play with the examples that you can find either in your ITK source
directory (Examples/DataRepresentation/Image/Image1.cxx, etc etc) or online
(
https://github.com/Kitware/ITK/blob/master/Examples/DataRepresentation/Image/Image1.cxxetc
etc)

If you want to cast image types (for example converting from unsigned short
to unsigned int), have a look at section "6.3 Casting and Intensity
Mapping" of the ITK software guide.

Hope it helps.

cheers,
Mauro
