Abstract: Scalable Vector Graphics (SVGs) have become integral in modern image
rendering applications due to their infinite scalability in resolution,
versatile usability, and editing capabilities. SVGs are particularly popular in
the fields of web development and graphic design. Existing approaches for SVG
modeling using deep learning often struggle with generating complex SVGs and
are restricted to simpler ones that require extensive processing and
simplification. This paper introduces StarVector, a multimodal SVG generation
model that effectively integrates Code Generation Large Language Models
(CodeLLMs) and vision models. Our approach utilizes a CLIP image encoder to
extract visual representations from pixel-based images, which are then
transformed into visual tokens via an adapter module. These visual tokens are
pre-pended to the SVG token embeddings, and the sequence is modeled by the
StarCoder model using next-token prediction, effectively learning to align the
visual and code tokens. This enables StarVector to generate unrestricted SVGs
that accurately represent pixel images. To evaluate StarVector's performance,
we present SVG-Bench, a comprehensive benchmark for evaluating SVG methods
across multiple datasets and relevant metrics. Within this benchmark, we
introduce novel datasets including SVG-Stack, a large-scale dataset of
real-world SVG examples, and use it to pre-train StarVector as a large
foundation model for SVGs. Our results demonstrate significant enhancements in
visual quality and complexity handling over current methods, marking a notable
advancement in SVG generation technology. Code and models:
