Hi Wojcieh,
take a look at the project template example interactor:
https://github.com/MITK/MITK-ProjectTemplate/blob/master/Modules/MyAwesomeLib/src/AwesomeImageInteractor.cpp
It allows painting the image in both 2D and 3D and has some explanatory
comments.
Best,
Caspar

Betreff: [mitk-users] writting a pixel od a mitkImage
Hi I am trying to paint an mitkimage, by mouse clicking and dragging. (painting
both the image and the rendered part would be nice).
To do this I am trying to use ImagePixelWriteAccessor but i dont really know
how to use it.
The example shown in http://docs.mitk.org/nightly/MitkImagePage.html says
itk::Index<2> idx = {{ 12, 34 }};
mitk::ImagePixelWriteAccessor<short,2> writeAccess(image,
image->GetSliceData(4));
writeAccess.SetPixelByIndex(idx, 42);
while the documentatiom says
void
SetPixelByIndex<http://docs.mitk.org/nightly/classmitk_1_1ImagePixelWriteAccessor.html#a7362a491a7724bbdb225abff1337648a>
(const itk::Index<http://docs.mitk.org/nightly/classitk_1_1Index.html><
VDimension > &idx, const TPixel &value)
as I understand, the ImagePixelWriteAccessor first asks for an image and a
slice, and than allows to set a certain pixel of
itk::Index<http://docs.mitk.org/nightly/classitk_1_1Index.html> coordinates
with TPixel value which basically say how grey-ish is it.
1 how can i get the current slice data that is in render window (4 doesn't seem
like good hint)?
2 where do I get the
itk::Index<http://docs.mitk.org/nightly/classitk_1_1Index.html> from
(mousePressed->x and y vary on the size of the screen while image dimension is
an int).
3 what is TPixel - cant find any documentation of it. Looks like an int, but is
it?
With regards,
Wojciech Lassmann
