slackbuilds_ponce/libraries/zimg

The "z" library implements the commonly required image processing
basics of scaling, colorspace conversion, and depth conversion. A
simple API enables conversion between any supported formats to operate
with minimal knowledge from the programmer. All library routines
were designed from the ground-up with correctness, flexibility, and
thread-safety as first priorities. Allocation, buffering, and I/O are
cleanly separated from processing, allowing the programmer to adapt
"z" to many scenarios.
