<br>Hi Ra,<br><br>If you are going to do this systematically <br>in an image, (that is, if you plan to search<br>for the diagonal pixel of every pixel), then<br>you probably should be using the<br><br> NeighborhoodIterator<br>
<br>Please look at the "Image Iterators" chapter<br><div class="gmail_quote">of the ITK Software Guide<br><br> <a href="http://www.itk.org/ItkSoftwareGuide.pdf">http://www.itk.org/ItkSoftwareGuide.pdf</a><br>
<br><br>Otherwise, if you are going to do this in only<br>one pixel, then the following code will suffice <br><br> ImageType::IndexType index = iterator.GetIndex();<br><br> ImageType::OffsetType offset;<br><br> offset[0] = 1;<br>
offset[1] = 1;<br> offset[2] = 0;<br><br> index += offset;<br><br> ImageType::PixelType pixelvalue = image->GetPixel( index );<br><br><br>This second method for accessing pixel values<br>is a lot slower than using Image Iterators.<br>

I want to use <b>operator</b>+=(<b>OffsetType</b>) but I don't know how I should do. My image is 512x512 so I would like an offset of 512.<br>
Than you in advance<br>Ra<br>
