Hi! I was trying to read some really big PSBs to do some calculations on, but not having much luck when the file gets too big. The example I have is 85K x 100K. 1. maketx and oiiotool crashes with segmentation fault 2. iconvert exits with the error "unable to decode packbits"
I managed to read/write scanline by scanline with ImageInput/ImageOutput while hacking madly, but the end result looked incorrect, like data had been teared or offset somehow. The memory load is pretty damn high as well, is it trying to read all of the image data into memory? I would think that by reading scanlines it wouldn't need to hold that much in memory. Any hints on how to best read PSB are greatly appreciated, I'm resorting to convert from PSB to tif with ImageMagick now before reading that through OIIO, but would prefer to read them directly since it quickly eats up storage. Are there known limitations with the PSB reader? Best regards, Jens
