Edit Compositions with Semantic Masking & Inpainting
Refine your images without starting over. dollyboard's semantic masking lets you select regions by description (not just boxes), enabling precise edits. Combine multiple images, apply style transfer, and iterate on composition—all without leaving the canvas.
Composition editing separates professional tools from basic image generators. dollyboard lets you refine images intelligently without losing what works. Semantic masking means you can select "the sky" or "the person on the left" and edit just that region, preserving the rest of your composition.
The inpainting engine understands context—if you remove an object, it intelligently fills the gap with appropriate backgrounds. If you change a subject, the surrounding elements adapt naturally. Multi-image prompting lets you upload a base image and additional reference images, then blend them seamlessly.
Style transfer is another powerful tool—lock down a composition you love, then transform the style to match a different aesthetic. All of this happens inside dollyboard's canvas, letting you iterate and refine without the friction of exporting to other tools.
How it works
Upload or generate a base image
Start with an existing image or generate a new one. This becomes your foundation for refinement.
Select and mask by description
Use semantic masking to select specific regions by what they are ('the building', 'the sky', 'the figure'), not just geometric shapes.
Refine with inpainting or style transfer
Edit your masked regions with new prompts, apply style transfer, or blend in elements from other images. Iterate until you're happy.
Why it matters
Intelligent region editing
Semantic masking understands what regions are, so you can select by description. Edit 'the sky' or 'the person' without drawing precise masks.
Preserve your best elements
Keep the parts of your image that work perfectly while iterating on other regions. No need to regenerate from scratch.
Multi-image blending
Combine elements from multiple images—upload a background, add objects, adjust lighting—all within the same canvas.
