Hello,
I have another issue. I'm reading an exr file, and the result is not
expected.
Code:
import OpenImageIO as oiio
import os, array
file_dir = 'C:\Users\digi\Pictures\inspiration'
image_path = os.path.join(file_dir, 'test.exr')
image_input = oiio.ImageInput.create(image_path)
image = image_input.open(image_path)
spec = image.spec()
data = array.array('d', '\0' * spec.image_bytes(True))
image.read_image(spec.format, data)
for channel in range(len(data)):
print(data[channel])
Result:
print: 5.9578290394e-39
