• Abstract: Creating visual layouts is an important step in graphic design. Automatic generation of such layouts is important as we seek scale-able and diverse visual designs. Prior works on automatic layout generation focus on unconditional generation, in which the models generate layouts while neglecting user needs for specific problems. To advance conditional layout generation, we introduce BLT, a bidirectional layout transformer. BLT differs from autoregressive decoding as it first generates a draft layout that satisfies the user inputs and then refines the layout iteratively. We verify the proposed model on multiple benchmarks with various fidelity metrics. Our results demonstrate two key advances to the state-of-the-art layout transformer models. First, our model empowers layout transformers to fulfill controllable layout generation. Second, our model slashes the linear inference time in autoregressive decoding into a constant complexity, thereby achieving 4x-10x speedups in generating a layout at inference time.

  Content-aware graphic layout generation aims to automatically arrange visual elements along with a given content, such as an e-commerce product image. We show that a simple retrieval augmentation can significantly improve the generation quality. Our model, which is named Retrieval-Augmented Layout Transformer (RALF), retrieves nearest neighbor layout examples based on an input image and feeds these results into an autoregressive generator.

  We generate graphic layouts that can flexibly incorporate design semantics, either specified implicitly or explicitly by a user. Our approach builds on a generative layout model based on a Transformer architecture, and formulates the layout generation as a constrained optimization problem. We show in the experiments that our approach is capable of generating realistic layouts in both constrained and unconstrained generation tasks with a single model.
