Hi, Matthew!
When you say half sizing, do you mean half resolution or half file size?
For half resolution you could do as follows:
####################BEGIN######################
import OpenImageIO as oiio
buf = oiio.ImageBuf('/path/to/fullsize.exr')
# Get the specs for original image to use in the resizes one
spec = buf.spec()
# Create a buffer set to half resolution
scaled = oiio.ImageBuf(oiio.ImageSpec(spec.full_width // 2, spec.full_width
// 2, spec.nchannels, spec.format))
#Slower, but higher quality resize
oiio.ImageBufAlgo.resize(scaled, buf)
# Faster, but not as good resize
#oiio.ImageBufAlgo.resample(scaled, buf)
# Write out your resized image
scaled.write('/path/to/resized.exr')
#####################END#####################
OIIO is well documented. There's a pdf in the doc folder of the source code
that covers pretty much everything. The image manipulation is mostly done
in the ImageBufAlgo functions.
Hope this helps,
