## Use graphicsTextMetricsV2

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

Verification: type checked

```yh
using graphics.text

// Shape, measure, and represent text and glyph resources.
graphicsTextMetricsV2 sample = graphicsTextMetricsV2(1, 1, 1, 1, 1, 1, 1, 1, 1)
Console.Log(Text.From(sample.ascentQ26_6))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.graphics_text__graphicstextmetricsv2"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

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

```

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.text--graphicsTextMetricsV2/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## graphicsTextMetricsV2.ValidationIssue

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

Verification: type checked

```yh
using graphics.text

// Validation issue.
graphicsTextMetricsV2 instance = graphicsTextMetricsV2(1, 1, 1, 1, 1, 1, 1, 1, 1)
text argument_source = "argument source"
text result = instance.ValidationIssue(argument_source)
Console.Log(Text.From(result))

```

Save this beside start.yh as project.mech:

[[dependencies]]
package = "graphics.text"

path = "../../../yeho/packages/graphics/text"

```

## graphicsTextMetricsV2.Snapshot

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

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