Hi oiio-dev!
I am trying to save on disk space and network bandwidth for our OIIO-based
texture pipeline and I am wondering what is a good lossy compression to use
for .tx files.
Has anyone ever tried and/or been successful at making mipped/tiled
"render-ready" .tx textures using good old "jpeg" compression ?
I've tried this with our build of maketx and got the following error:
maketx test_linear.exr -d uint8 --oiio --colorconvert linear sRGB --attrib
CompressionQuality 90 --compression jpeg -o test_srgb.tx
maketx ERROR: Write failed " : TIFFWriteTile failed writing tile
x=0,y=0,z=0 (Application transferred too few scanlines)
TIFFWriteTile failed writing tile x=0,y=64,z=0 (Application transferred too
few scanlines)
TIFFWriteTile failed writing tile x=0,y=128,z=0 (Application transferred
too few scanlines)
TIFFWriteTile failed writing tile x=0,y=192,z=0 (Application transferred
too few scanlines)
TIFFWriteTile failed writing tile x=0,y=256,z=0 (Application transferred
too few scanlines)
(message repeated until "y" reaches the vertical resolution of the input
texture)
For reference, I'm on Red-Hat 6 and maketx/OIIO uses:
ldd `which maketx` | grep tiff
libtiff.so.3 => /usr/lib64/libtiff.so.3 (0x00000036b7200000)
Does this look familiar to anyone ? Could it be our build or version of
libtiff that is fishy ?
Thanks for any insight!
:-)
Eric
