Image Resize Library Test

I want to start evaluating the state of rust and its image processing libraries. I do not expect many libraries to be very feature rich but can presume that they should be able to resize a image quickly with a variety of sampling algorithms.

Purpose
Goal is to see if migrating our image resizing app using sharp image library. Sharp can perform the same conversion of a 2000x2000 to an 150x150 image size in 0.101s. If we can beat this metric we have a purpose to investigate migrating further.

Build

Test must be built as a release for speed optimizations.

cargo build --release
cargo install

Test

cd test
./benchmark-72ppi.
