[Insight-users] PasteImage Filter

[Kannan U V]

Hi All,
I am trying to use PasteImageFilter on a grid of image tiles. (These
are tiles with overlap) I know the position of the tiles and I want to
paste them on to the montage. I am using pasteImage filter. When I use
the following routine and I get only the last written time in the
mosaic image and all other regions are set to zero.

Moreover if I don't do a set regions on the mosaicImage I get a write
error on image writer. I need help figuring out how it has to be run.

 for (int iY = 1; iY < 2; iY++) {
    for (int iX = 1; iX < 3; iX++) {
      cout << "Processing tile : (" << iX << "," << iY << ")" << endl;
      CreateConstantImage (tileImage, (iX + iY));
      pasteFilter->SetSourceImage(tileImage);
      pasteFilter->SetDestinationImage (mosaicImage);
      pasteFilter->SetSourceRegion(tileImage->GetLargestPossibleRegion());

      mosaicIndex1[0] = iX * 812;
      mosaicIndex1[1] = iY * 812;
      pasteFilter->SetDestinationIndex(mosaicIndex1);

      mosaicImage = pasteFilter->GetOutput();
      mosaicImage->SetRegions(region);

  }
