## Use graphicsImageSamplingPolicyV1

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

Verification: type checked

```yh
using graphics.image.processing

// Transform image data through the package's explicit processing contracts.
graphicsImageSamplingPolicyV1 sample = graphicsImageSamplingPolicyV1("filter", "source Color Space", "source Alpha Mode", "output Color Space", "example")
Console.Log(Text.From(sample.schema))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.graphics_image_processing__graphicsimagesamplingpolicyv1"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "graphics.image.processing"
version = "0.1.0"
path = "../../../yeho/packages/graphics/image/processing"

```

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/graphics.image.processing--graphicsImageSamplingPolicyV1/usage --backend cpu-oracle -o /tmp/yeho-example

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