How to release memory after completing a task of converting PNG to AVIF about govips HOT 1 CLOSED

Considering your Close()ing the image properly, that's an issue with Golang memory management. There's nothing we can do in the govips library side to help you, unfortunately.

I suggest you check the golang garbage collector guide: https://tip.golang.org/doc/gc-guide

Here's another useful resource: https://concertio.com/blog/optimizing-the-go-garbage-collector-and-concurrency/

I seem to recall the latest golang versions provided some new control over the gc, in addition to the env variables mentioned in the above posts. I personally handled this by doing heavy image processing in separate goroutines, which are spawned and killed for each task as part of a pool.
