## Use graphicsImagePresentationColorPolicyV1

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.
graphicsImagePresentationColorPolicyV1 sample = graphicsImagePresentationColorPolicyV1("source Color Space", "tint Color Space", "destination Color Space", "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__graphicsimagepresentationcolorpolicyv1"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]

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