Hi Larry,
I'm having a problem when making thumbnails from tiff images where the results
image is coming out darker and less saturated than the source.
When using oiiotool.exe it results in a proper output but the issue happens
when I do the conversion myself from the python API.
Any idea why this is happening ?
Thanks !
Trimmed down code:
from OpenImageIO import OpenImageIO as oiio
from OpenImageIO.OpenImageIO import ImageBufAlgo, ImageBuf, ImageSpec,
ImageInput
sourceImgPath = "C:/temp/ataafm_diff_v001.1005.tif"
sourceImg = ImageInput.open(sourceImgPath)
spec = sourceImg.spec()
pixels = sourceImg.read_image(0, 3, oiio.UINT8)
sourceBufSpec = ImageSpec(spec.width, spec.height, 3, oiio.UINT8)
sourceBuf = ImageBuf(sourceBufSpec)
sourceBuf.set_pixels(oiio.ROI.All, pixels)
resizedImgSpec = ImageSpec(int(120), int(120), 3, oiio.UINT8)
resizedBuf = ImageBuf(resizedImgSpec)
ImageBufAlgo.resample(resizedBuf, sourceBuf)
# Set input colorspace to linear if converting EXR file
if sourceImgPath.split('.')[-1] == 'exr':
ImageBufAlgo.colorconvert(resizedBuf, resizedBuf, 'linear', 'sRGB')
resizedBuf.write('C:/temp/test_oiio.jpg')
