Hi all,
I have images with the datatype NIFTI_TYPE_RGB24 (128):
bitpix = 24
datatype = 128
dim[0] = 3
dim[1] = 192
dim[2] = 256
dim[3] = 160
However when I load an image into Paraview, the slices don't show up as RGB. I
think the data is being written correctly. To verify this, I took the same
binary data (the contents of the nii file minus the 352 byte header), and added
a Meta header:
ObjectType = Image
NDims = 3
BinaryData = True
BinaryDataByteOrderMSB = False
CompressedData = False
TransformMatrix = 1 0 0 0 -1 0 0 0 1
Offset = -93 143 -72
CenterOfRotation = 0 0 0
AnatomicalOrientation = RPI
ElementSpacing = 0.976562 0.976562 1
DimSize = 192 256 160
ElementNumberOfChannels = 3
ElementType = MET_UCHAR
ElementDataFile = LOCAL
The resulting image displays correctly as RGB. Unfortunately, the geometry of
the image is often confused by the conversion between nii and mha files, so it
would be really helpful if I could load RGB .nii images directly. Is there a
way to read RGB images in NIfTI-1 format?
Thanks,
Phil
