Hello all,
I'm writing a script to help operators inspect all available channels that
aren't RGB in an EXR. I'd like to create a 1fps GIF that shows all non-RGB
channels.
I am able to extract each channel and save it as JPG, but not finding the
proper syntax to save it as an animated GIF.
What I have so far:
import OpenImageIO as oiio
from OpenImageIO import ImageInput, ImageOutput
from OpenImageIO import ImageBuf, ImageSpec, ImageBufAlgo, ROI
input_path = 'vfx.exr'
img = oiio.ImageBuf(input_path)
for ch in [c for c in spec.channelnames if not c in ['R', 'G', 'B']]:
ch_img = ImageBufAlgo.channels(img, (ch,ch,ch), newchannelnames=("R",
"G", "B"))
ch_img = ImageBufAlgo.fit(ch_img, roi=ROI(0,640,0,480,0,1,0,3))
ImageBufAlgo.render_text(ch_img, x=0, y=100, text=ch, textcolor=(1,1,1,1
))
ch_img.write("{}.jpg".format(ch) ##
Thanks in advance for your help.
Best,
Jerome
