DesignAsCode Image Library

This dataset provides the image retrieval assets used by the DesignAsCode graphic design generation pipeline. It contains a large collection of design element images along with a pre-built FAISS index for semantic retrieval.

The images are sourced from the Crello dataset. We extracted the semantic representation of every element image using sentence-transformers/all-mpnet-base-v2 and built a FAISS index to enable fast text-to-image retrieval.

Files

File	Size	Description
crello_pngs.tar.gz	~18 GB	Archive of ~228K PNG design element images (backgrounds, shapes, icons, photos, etc.)
elements_local.index	~370 MB	Pre-built FAISS index for semantic similarity search over all element images
id_mapping_local.json	~4.6 MB	JSON mapping from FAISS index positions to image file IDs

How It Works

The DesignAsCode pipeline uses these files during the Retrieve stage:

1. The planner model generates image prompts for each design layer (e.g., "Abstract geometric background in teal")
2. Each prompt is encoded into an embedding via sentence-transformers/all-mpnet-base-v2
3. The FAISS index (elements_local.index) finds the most similar image by vector similarity
4. The ID mapping (id_mapping_local.json) translates the FAISS result index to an image filename
5. The corresponding PNG is copied from the image library (crello_pngs/) into the design output

Quick Setup

pip install huggingface_hub

# Download all files
huggingface-cli download Tony1109/crello-image-library --repo-type dataset --local-dir .

# Extract the image archive
tar -xzf crello_pngs.tar.gz

Then place the files in the data/ directory of your DesignAsCode project:

design-as-code/
└── data/
    ├── image_library/            # extracted from crello_pngs.tar.gz (renamed)
    ├── elements_local.index      # FAISS index
    └── id_mapping_local.json     # index → image ID mapping

See the Quick Start Guide for full instructions.
