AcademySoftwareFoundation/OpenImageIO Release-2.1.12.0 on GitHub

Release 2.1.12 (2 Mar 2020) -- compared to 2.1.11

Fix: plugin.h getsym() didn't pass along its report_error param. #2465
Fix: ImageBuf::getchannel() did not honor its wrap parameter. #2465
Fix: ImageSpec::erase_attribute() did not honor its searchtype param. #2465
Fix: IBA::reorient() and IBA::computePixelsHashSHA1() did not honor their
nthreads parameter. #2465.
IBA::resample() now uses the clamp wrap mode to avoid black fringing and
match the behavior of resize(). #2481
Fix: ImageBuf::get_pixels() did not honor the stride parameters. #2487.
fmath.h perf improvements: clamp() is 2x faster; madd() is improved
especially on platforms without fma hardware; perf improvements in
fast_sin, fast_cos; new safe_fmod is faster than std::fmod, new
fast_neg is faster than simple negation in many cases, if you don't care
that -(0.0) is 0.0 (rather than a true -0.0). #2491 #2492 #2494
strutil: New function: concat(). #2478
Build: un-embed the 'fmt' headers, instead auto-download if not found.
#2439
Build: Protect against certain compiler preprocessor errors for user
programs that include strutil.h but also inculde fmt on its own. #2498.
