# Outpainting
|
|
|
|
Extend an image beyond its original borders.
|
|
|
|
## How It Works
|
|
|
|
1. Place original image on larger canvas
|
|
2. Mask the empty areas (white = generate here)
|
|
3. Describe what should appear in extended areas
|
|
4. AI generates content matching style and context
|
|
|
|
## Tools
|
|
|
|
### DALL-E 2 (OpenAI)
|
|
|
|
```python
|
|
from openai import OpenAI
|
|
from PIL import Image
|
|
import io
|
|
|
|
client = OpenAI()
|
|
|
|
# Create extended canvas
|
|
original = Image.open("photo.png")
|
|
extended = Image.new("RGBA", (1024, 1024), (0, 0, 0, 0))
|
|
extended.paste(original, (256, 256)) # Center original
|
|
|
|
# Create mask (transparent = edit)
|
|
mask = Image.new("RGBA", (1024, 1024), (255, 255, 255, 255))
|
|
mask.paste(Image.new("RGBA", original.size, (0, 0, 0, 0)), (256, 256))
|
|
|
|
response = client.images.edit(
|
|
model="dall-e-2",
|
|
image=to_bytes(extended),
|
|
mask=to_bytes(mask),
|
|
prompt="Continue the landscape with mountains in the distance"
|
|
)
|
|
```
|
|
|
|
### Stable Diffusion Outpaint
|
|
|
|
```python
|
|
from diffusers import StableDiffusionInpaintPipeline
|
|
|
|
# Same as inpainting, but with extended canvas
|
|
# Original image centered, mask covers new areas
|
|
|
|
pipe = StableDiffusionInpaintPipeline.from_pretrained(
|
|
"runwayml/stable-diffusion-inpainting",
|
|
torch_dtype=torch.float16
|
|
)
|
|
|
|
result = pipe(
|
|
prompt="expansive landscape, same style",
|
|
image=extended_image,
|
|
mask_image=outpaint_mask,
|
|
num_inference_steps=50
|
|
).images[0]
|
|
```
|
|
|
|
### Photoshop Generative Fill
|
|
|
|
1. Select > All
|
|
2. Image > Canvas Size (increase dimensions)
|
|
3. Select empty areas with Magic Wand
|
|
4. Edit > Generative Fill
|
|
5. Enter prompt or leave blank
|
|
|
|
## Aspect Ratio Expansion
|
|
|
|
**Portrait to Landscape:**
|
|
- Extend left and right
|
|
- Prompt for environmental context
|
|
|
|
**Landscape to Portrait:**
|
|
- Extend top and bottom
|
|
- Consider sky above, ground below
|
|
|
|
**Square to Cinematic (16:9):**
|
|
- Add 280px each side for 1080p
|
|
- Describe scene continuation
|
|
|
|
## Best Practices
|
|
|
|
- **Overlap slightly** — let AI see edge context
|
|
- **Match lighting direction** — describe consistent light
|
|
- **Extend in steps** — don't 4x the canvas at once
|
|
- **Describe style** — "same artistic style", "photorealistic"
|
|
|
|
## Common Issues
|
|
|
|
- **Style mismatch** — add style keywords to prompt
|
|
- **Repeated elements** — AI may duplicate objects
|
|
- **Perspective errors** — complex scenes may warp
|
|
- **Seam lines** — blend with photo editor after
