Hi!
I'm attempting to render text with 40% opacity in python without success.
OIIO 2.2.10.1
``` python
import OpenImageIO as oiio
buf = oiio.ImageBuf(oiio.ImageSpec(640, 480, 4 oiio.FLOAT))
oiio.ImageBufAlgo.render_text(buf, 100, 200, "Hello, World!", 60,
"FreeSans", (1, 1, 1, 0.4))
buf.write('transparent_text_test.exr')
```
Am I doing something wrong?
Any pointers would be greatly appreciated.
Thanks,
--
