Hi David, <br><br><div><div>The following snippet should do what you need:</div><div><br><div><div> vtkImageData* cachedImage = ...;</div><div> int width = cachedImage->GetDimensions()[0];</div><div> int height = cachedImage->GetDimensions()[1];</div>
<div> QImage qImage(width, height, QImage::Format_RGB32);</div><div> QRgb* rgbPtr = reinterpret_cast<QRgb*>(qImage.bits());</div><div> unsigned char* colorsPtr = reinterpret_cast<unsigned char*>(cachedImage->GetScalarPointer());</div>
<div> for(int i = 0; i < width * height; ++i)</div><div> {</div><div> *(rgbPtr++) = QColor(colorsPtr[0], colorsPtr[1], colorsPtr[2]).rgb();</div><div> colorsPtr += 3;</div><div> }</div><div><br>
</div><div>Regards,</div><div>Julien.</div><div><br><div class="gmail_quote">On Fri, Sep 16, 2011 at 3:24 PM, David Doria <span dir="ltr"><<a href="mailto:daviddoria@gmail.com">daviddoria@gmail.com</a>></span> wrote:<br>
