Wanted to do this myself and ended up here. Turns out Skia appears to be the simplest packaged way (for newer Delphi). Tried it myself using FMX (though VCL would be almost identical)

Skia is (as with most things Delphi) not overflowing with documentation

To this end I've left a very low effort demo at https://github.com/IntermediateDelphi/SkiaResampleDemo in the hope that the next person who ends up here finds it useful
