# Ideogram Core Workflow A -- Text-to-Image Generation

## Overview

Primary workflow for Ideogram: generating images from text prompts. Ideogram excels at rendering legible text inside images -- a capability where most image models fail. Use this for social media graphics, marketing banners, product mockups, posters, logos, and any visual that combines illustration with typography.

## Prerequisites

- Completed `ideogram-install-auth` setup
- `IDEOGRAM_API_KEY` environment variable set
- Understanding of style types and aspect ratios

## Instructions

### Step 1: Choose Parameters for Your Use Case

| Use Case | Style Type | Aspect Ratio | Model | Notes |
|----------|-----------|--------------|-------|-------|
| Social media post | `DESIGN` | `ASPECT_1_1` | `V_2` | Best text rendering |
| Blog hero image | `REALISTIC` | `ASPECT_16_9` | `V_2` | Photorealistic |
| Story / Reel | `GENERAL` | `ASPECT_9_16` | `V_2_TURBO` | Fast, vertical |
| Logo / Icon | `DESIGN` | `ASPECT_1_1` | `V_2` | Clean typography |
| Product mockup | `REALISTIC` | `ASPECT_4_3` | `V_2` | Studio quality |
| Anime illustration | `ANIME` | `ASPECT_3_4` | `V_2` | Japanese art style |
| 3D render | `RENDER_3D` | `ASPECT_16_9` | `V_2` | 3D scene |
| Wide banner | `DESIGN` | `ASPECT_3_1` | `V_2` | Website header |

### Step 2: Generate Image (Legacy Endpoint)

```typescript
import { writeFileSync, mkdirSync } from "fs";

async function generateImage(prompt: string, options: {
  model?: string;
  style_type?: string;
  aspect_ratio?: string;
  negative_prompt?: string;
  seed?: number;
} = {}) {
  const response = await fetch("https://api.ideogram.ai/generate", {
    method: "POST",
    headers: {
      "Api-Key": process.env.IDEOGRAM_API_KEY!,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      image_request: {
        prompt,
        model: options.model ?? "V_2",
        style_type: options.style_type ?? "DESIGN",
        aspect_ratio: options.aspect_ratio ?? "ASPECT_1_1",
        magic_prompt_option: "AUTO",
        negative_prompt: options.negative_prompt,
        seed: options.seed,
        num_images: 1,
      },
    }),
  });

  if (!response.ok) {
    const err = await response.text();
    throw new Error(`Generation failed (${response.status}): ${err}`);
  }

  const result = await response.json();
  const image = result.data[0];

  // Download immediately -- URLs expire after ~1 hour
  const imgResp = await fetch(image.url);
  const buffer = Buffer.from(await imgResp.arrayBuffer());
  mkdirSync("./output", { recursive: true });
  const filename = `ideogram-${image.seed}.png`;
  writeFileSync(`./output/${filename}`, buffer);

  return { ...image, localPath: `./output/${filename}` };
}
```

### Step 3: Generate with V3 Endpoint (Multipart)

```typescript
async function generateV3(prompt: string, options: {
  aspect_ratio?: string;
  style_type?: string;
  rendering_speed?: string;
  negative_prompt?: string;
  magic_prompt?: string;
  style_preset?: string;
} = {}) {
  const form = new FormData();
  form.append("prompt", prompt);
  form.append("aspect_ratio", options.aspect_ratio ?? "1x1");
  form.append("style_type", options.style_type ?? "DESIGN");
  form.append("rendering_speed", options.rendering_speed ?? "DEFAULT");
  form.append("magic_prompt", options.magic_prompt ?? "AUTO");
  if (options.negative_prompt) form.append("negative_prompt", options.negative_prompt);
  if (options.style_preset) form.append("style_preset", options.style_preset);

  const response = await fetch("https://api.ideogram.ai/v1/ideogram-v3/generate", {
    method: "POST",
    headers: { "Api-Key": process.env.IDEOGRAM_API_KEY! },
    body: form,
  });

  if (!response.ok) throw new Error(`V3 generation failed: ${response.status}`);
  return response.json();
}
```

### Step 4: Text-in-Image Best Practices

```typescript
// Ideogram renders quoted text literally inside the image
const textPrompts = [
  // Enclose desired text in quotes within the prompt
  'A coffee shop chalkboard menu with text "DAILY SPECIALS" and "Latte $4.50"',
  'A retro neon sign glowing with the words "OPEN 24 HOURS"',
  'Professional business card design with "Jane Smith" and "CEO" text',
  'Birthday card with elegant gold script "Happy Birthday!"',
];

// Use DESIGN style for best text accuracy
for (const prompt of textPrompts) {
  const result = await generateImage(prompt, {
    style_type: "DESIGN",
    negative_prompt: "blurry text, misspelled, distorted letters",
  });
  console.log(`Generated: ${result.localPath} (seed: ${result.seed})`);
}
```

### Step 5: Batch Generation with Seed Consistency

```typescript
// Use the same seed to reproduce or create consistent variations
async function generateVariations(basePrompt: string, seed: number) {
  const variations = [
    { suffix: ", minimalist style", style: "DESIGN" },
    { suffix: ", photorealistic", style: "REALISTIC" },
    { suffix: ", anime style", style: "ANIME" },
  ];

  const results = [];
  for (const v of variations) {
    const result = await generateImage(`${basePrompt}${v.suffix}`, {
      style_type: v.style,
      seed,
    });
    results.push(result);
    await new Promise(r => setTimeout(r, 3000)); // Rate limit courtesy
  }
  return results;
}
```

## V3 Style Presets (50+)

`80S_ILLUSTRATION`, `90S_NOSTALGIA`, `ART_DECO`, `ART_POSTER`, `BAUHAUS`, `BLUEPRINT`, `BRIGHT_ART`, `CHILDRENS_BOOK`, `COLLAGE`, `CUBISM`, `DOUBLE_EXPOSURE`, `DRAMATIC_CINEMA`, `EDITORIAL`, `FLAT_ART`, `FLAT_VECTOR`, `GOLDEN_HOUR`, `GRAFFITI_I`, `HALFTONE_PRINT`, `JAPANDI_FUSION`, `LONG_EXPOSURE`, `MAGAZINE_EDITORIAL`, `MIXED_MEDIA`, `MONOCHROME`, `OIL_PAINTING`, `POP_ART`, `RETRO_ETCHING`, `SURREAL_COLLAGE`, `TRAVEL_POSTER`, `VINTAGE_POSTER`, `WATERCOLOR`, and more.

## V3 Rendering Speeds

| Speed | Quality | Cost | Use Case |
|-------|---------|------|----------|
| `FLASH` | Lowest | Cheapest | Quick previews |
| `TURBO` | Good | Low | Drafts, iteration |
| `DEFAULT` | High | Standard | Production assets |
| `QUALITY` | Highest | Premium | Final deliverables |

## Error Handling

| Error | HTTP Status | Cause | Solution |
|-------|-------------|-------|----------|
| Content filtered | 422 | Prompt failed safety check | Remove brand names, trademarks, or flagged terms |
| Bad aspect ratio | 400 | Invalid enum value | Use exact enum values (e.g., `ASPECT_16_9` not `16:9`) |
| Rate limited | 429 | 10+ in-flight requests | Queue with 3s delays between calls |
| Expired URL | -- | Downloaded too late | Fetch image within minutes of generation |

## Output

- Generated image files downloaded to `./output/`
- Metadata: URL, seed, resolution, style type, safety status
- Seed values logged for reproducibility
