<DIV id=RTEContent>Hi,</DIV> <DIV> </DIV> <DIV>I have to save an image of 55*239 pixels with spacing as 0.1496*0.01925. </DIV> <DIV> </DIV> <DIV>This seems to be easy. However, the image saved is not taking into account my pixel size but just the number of my pixels. </DIV> <DIV> </DIV> <DIV><FONT face="Courier New" size=2> <div><STRONG><EM>ImageType::IndexType start;</EM></STRONG></div> <div><STRONG><EM>start.Fill(0); </EM></STRONG></div> <div><STRONG><EM></EM></STRONG> </div> <div><STRONG><EM>ImageType::SizeType sz;</EM></STRONG></div> <div><STRONG><EM>sz[0] = 239; </EM></STRONG></div> <div><STRONG><EM>sz[1] = 55;</EM></STRONG></div> <div><STRONG><EM></EM></STRONG> </div> <div><STRONG><EM>ImageType::RegionType region;</EM></STRONG></div> <div><STRONG><EM>region.SetSize( sz );</EM></STRONG></div> <div><STRONG><EM>region.SetIndex( start );</EM></STRONG></div> <div><STRONG><EM></EM></STRONG> </div> <div><STRONG><EM>ImageType::Pointer

size is very important to be aware of the physical dimensions of the image.</div> <div> </div> <div>Isabelle</div> <div> </div></FONT></FONT></DIV><p>
