Hi, It's a concept question, I tough that vtkImageData spacing was the real distance between each pixel or pixel size, so if spacing[0] is 0.5 the lenght of a pixel along the axis is 0.5 in units(mm).<div><br></div><div>
But After use vtkImageReslice, the output spaicng change to 1.0 1.0 1.0 where the input spacing was 0.3 0.3 0.5, I though it would chage the size of my image data, the real size, but seems that the image still having the same real size, so I got to be wrong about spacing.</div>
<div><br></div><div><br></div><div>Is not "spacing" the space between cells/points/pixels ? </div><div>If I got spacing = 1.0 means that I got a cells/points/pixels each 1.0 units (mm) ?</div><div><br></div><div>
Thanks</div>
