Hello @strangerism,
Yes, libvips keeps a cache of recent operations and returns old results if you repeat a call. This is usually a good thing, but in your case it's obviously not what you want.
You have a couple of choices:
- Disable the cache. You can use
pyvips.cache_set_max()
to set the number of cached operations. Set it to zero to disable the caching system. - Use
access="sequential"
. You could ask for the image to be streamed. You won't be able to reuse pixels, but the image won't be cached.

@jcupitt Thank you for the quick reply. Indeed, I have used access options and it works as I need it now.
I am closing this issue.
best wishes.
