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
