## Use yuiPreparedImageRegionV1

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using frontend.yui

// Turn YUI models into a working frontend and its rendering/input adapters.
yuiPreparedImageRegionV1 sample = yuiPreparedImageRegionV1("example")
Console.Log(Text.From(sample.available))

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/frontend.yui--yuiPreparedImageRegionV1/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## yuiPreparedImageRegionV1.Snapshot

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using frontend.yui

// Snapshot.
yuiPreparedImageRegionV1 instance = yuiPreparedImageRegionV1("example")
text result = instance.Snapshot()
Console.Log(Text.From(result))

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
