## What it does

The skill covers `com.azure:azure-ai-vision-imageanalysis`, the Java client for Azure AI Vision. It shows how to build `ImageAnalysisClient` and `ImageAnalysisAsyncClient`, authenticate with `KeyCredential` or `DefaultAzureCredential`, and call the visual features: `CAPTION`, `DENSE_CAPTIONS`, `READ`, `TAGS`, `OBJECTS`, `SMART_CROPS`, `PEOPLE`.

Every feature comes with a code sample. Pass an image as a file with `BinaryData.fromFile` or as a URL through `analyzeFromUrl`, read the caption text with its confidence, walk OCR blocks and lines, pull bounding boxes for objects and people. Smart crops take aspect ratios in the options, captions take a gender-neutral flag and a language.

The samples read `VISION_ENDPOINT` and `VISION_KEY` from `System.getenv`, so without those variables the client will not build. For production the authors point to `ManagedIdentityCredential` instead of a key. The dependency in the sample is pinned to `1.1.0-beta.1`, a beta release.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add microsoft/skills --skill azure-ai-vision-imageanalysis-java -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/azure-ai-vision-imageanalysis-java/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/azure-ai-vision-imageanalysis-java/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/azure-ai-vision-imageanalysis-java/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/azure-ai-vision-imageanalysis-java/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills azure-ai-vision-imageanalysis-java
```

2. **Manually: put the files in place**
- File: `.github/skills/azure-ai-vision-imageanalysis-java/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/azure-sdk-java/skills/azure-ai-vision-imageanalysis-java
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/azure-ai-vision-imageanalysis-java/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/microsoft/skills/tree/HEAD/.github/plugins/azure-sdk-java/skills/azure-ai-vision-imageanalysis-java/SKILL.md

## When to use it
- generate an image caption in Java
- extract text from a scanned document
- detect objects and return their bounding boxes
- tag what is in a photo
- crop a thumbnail to a target aspect ratio

## Example prompts
- Write Java code that gets a caption for `image.jpg` with Azure AI Vision
- Add OCR to this project: read the text on the scan and print lines with coordinates
- Detect objects in the image at this URL and print the boxes with confidence

# Azure AI Vision Image Analysis SDK for Java

Build image analysis applications using the Azure AI Vision Image Analysis SDK for Java.

## Installation

```xml
<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-ai-vision-imageanalysis</artifactId>
    <version>1.1.0-beta.1</version>
</dependency>
```

## Client Creation

### With API Key

```java
import com.azure.ai.vision.imageanalysis.ImageAnalysisClient;
import com.azure.ai.vision.imageanalysis.ImageAnalysisClientBuilder;
import com.azure.core.credential.KeyCredential;

String endpoint = System.getenv("VISION_ENDPOINT");
String key = System.getenv("VISION_KEY");

ImageAnalysisClient client = new ImageAnalysisClientBuilder()
    .endpoint(endpoint)
    .credential(new KeyCredential(key))
    .buildClient();
```

### Async Client

```java
import com.azure.ai.vision.imageanalysis.ImageAnalysisAsyncClient;

ImageAnalysisAsyncClient asyncClient = new ImageAnalysisClientBuilder()
    .endpoint(endpoint)
    .credential(new KeyCredential(key))
    .buildAsyncClient();
```

### With DefaultAzureCredential

```java
import com.azure.core.credential.TokenCredential;
import com.azure.identity.AzureIdentityEnvVars;
import com.azure.identity.DefaultAzureCredentialBuilder;
import com.azure.identity.ManagedIdentityCredentialBuilder;

TokenCredential credential = new DefaultAzureCredentialBuilder()
    .requireEnvVars(AzureIdentityEnvVars.AZURE_TOKEN_CREDENTIALS)
    .build();
// Or use a specific credential directly in production:
// See https://learn.microsoft.com/java/api/overview/azure/identity-readme?view=azure-java-stable#credential-classes
// TokenCredential credential = new ManagedIdentityCredentialBuilder().build();

ImageAnalysisClient client = new ImageAnalysisClientBuilder()
    .endpoint(endpoint)
    .credential(credential)
    .buildClient();
```

## Visual Features

| Feature | Description |
|---------|-------------|
| `CAPTION` | Generate human-readable image description |
| `DENSE_CAPTIONS` | Captions for up to 10 regions |
| `READ` | OCR - Extract text from images |
| `TAGS` | Content tags for objects, scenes, actions |
| `OBJECTS` | Detect objects with bounding boxes |
| `SMART_CROPS` | Smart thumbnail regions |
| `PEOPLE` | Detect people with locations |

## Core Patterns

### Generate Caption

```java
import com.azure.ai.vision.imageanalysis.models.*;
import com.azure.core.util.BinaryData;
import java.io.File;
import java.util.Arrays;

// From file
BinaryData imageData = BinaryData.fromFile(new File("image.jpg").toPath());

ImageAnalysisResult result = client.analyze(
    imageData,
