When Imageflow does remove cached images

Question

I use the Imageflow package for resizing image in asp.net core.

it cache the images in imageflow_cache folder. But I don't know when cached images are deleted?

This is my configuration:

builder
    .Services
    .AddImageflowHybridCache(new HybridCacheOptions(Path.Combine(builder.Environment.WebRootPath, 
                                                                 "imageflow_cache"))
{
    CacheSizeLimitInBytes = (long)1 * 1024 * 1024 * 1024 //1 GiB
});

When cached images are delete in imageflow_cache folder?

Can I set a time for deleting cached images?

@JasonPan No, I want to know when images are deleted. your answer was very helpful. (for DiskCache not Hybrid) — Farhad Zamani, Apr 17 '23 at 07:54
Hi Farhad, I found this link [DiskCache and Tiny Cache have been replaced by HybridCache](https://github.com/imazen/resizer/blob/develop/CHANGES.md#diskcache-and-tiny-cache-have-been-replaced-by-hybridcache). — Jason Pan, Apr 17 '23 at 09:08
The two packages seem have some relationship, I didn't confuse them. — Jason Pan, Apr 17 '23 at 09:10

I read the source code and found CleanupStrategy.

I haven't the resources like you,So I according the source code and write code snipt below, you can refer it, if some properties not found, try to F12 and find it or share with us. Hope the code useful to you.

builder.Services.AddImageflowHybridCache(new HybridCacheOptions(Path.Combine(builder.Environment.WebRootPath, "imageflow_cache"))
{
    CacheSizeLimitInBytes = (long)1 * 1024 * 1024 * 1024, //1 GiB
    AutoClean = true,
    CleanupStrategy = "d.01:00:00" // delete files older than 1 day
});
