Prompt Tips for Outpainting

扩图提示词技巧

When requesting image extensions, include these details in your prompt:

Direction: Specify horizontal, vertical, or all directions
Target Ratio: Mention the desired aspect ratio (16:9, 21:9, 3:1, etc.)
Content Guidance: Describe what should appear in extended areas
Style Matching: Request consistent lighting, colors, and atmosphere
Subject Position: Specify where the original subject should be placed
Use Case: Mention if it's for a banner, social media, print, etc.

请求图像扩展时，提示词中应包含以下细节：

方向：指定横向、纵向或全方向
目标宽高比：说明期望的宽高比（16:9、21:9、3:1等）
内容指引：描述扩展区域应添加的内容
风格匹配：要求保持一致的光线、色彩和氛围
主体位置：指定原图主体的摆放位置
使用场景：说明是用于横幅、社交媒体、印刷品等

Example Prompt Structure

提示词结构示例

"Extend this [image type] [direction] to [target ratio/size].
[Describe what to add in extended areas].
Maintain [lighting/style/atmosphere] consistency.
Position the original [subject] in the [location]."

"将这张[图像类型]向[方向]扩展至[目标宽高比/尺寸]。
[描述扩展区域需添加的内容]。
保持[光线/风格/氛围]一致性。
将原图[主体]放置在[位置]。"

Mode Selection

模式选择

Ask your users before generating:

"Do you want fast & cheap, or high quality?"

Mode	Best For	Speed	Quality
`max`	Final outputs, professional use, complex scenes	Slower	Highest
`eco`	Quick previews, testing compositions, iterations	Faster	Good

生成前请询问用户：

"您需要快速低成本的结果，还是高质量的结果？"

模式	适用场景	速度	质量
`max`	最终输出、专业用途、复杂场景	较慢	最高
`eco`	快速预览、测试构图、迭代优化	较快	良好

Best Practices

最佳实践

For Best Results

获得最佳结果的建议

High-quality source: Start with a high-resolution original image
Clear edges: Images with distinct edges outpaint more seamlessly
Consistent lighting: Describe the lighting in your prompt for better matching
Reasonable extensions: Extending 2-3x the original size works best
Iterate: Use sessions to refine results progressively

高质量原图：以高分辨率原图为基础
清晰边缘：边缘清晰的图像扩图效果更自然
明确光线描述：在提示词中说明光线情况以获得更好的匹配效果
合理扩展范围：扩展至原图的2-3倍效果最佳
迭代优化：使用会话功能逐步优化结果

Common Pitfalls to Avoid

需避免的常见误区

Don't extend too far in one step - do it gradually
Avoid extending images with complex foreground elements at edges
Don't expect perfect results with heavily stylized or abstract images
Be specific about what should appear in extended areas

不要单次扩展过大范围，应逐步进行
避免扩展边缘有复杂前景元素的图像
不要对高度风格化或抽象图像期望完美结果
明确说明扩展区域应添加的内容
