You can convert between planar configurations (for formats that support the
distinction) on the command line with oiiotool:
oiiotool myinterleaved.tif --planarconfig separate -o myseparate.tif
oiiotool mycontiguous.tif --planarconfig contig -o myinterleaved.tif
If you're using the C++ interface, you don't have to actually "do" anything, no
shuffling of memory on your own, it's all handled in the output just by setting
that one attribute for the output configuration.
I'm not sure what you mean by "padding". Can you explain what you're trying to
achieve?
Full PDF documentation (a 400 page book!) can be found in the OIIO distribution
itself. Look for openimageio.pdf.
