A method including receiving a compositional constraint from a user for merging multiple images to create a canvas, is provided. The method includes finding a vector for the canvas in a merged space associated with the compositional constraint, and generating a synthetic image for the canvas based on the vector for the canvas and a generative tool trained in a generative adversarial configuration against a discriminative tool. The method also includes providing the synthetic image for the canvas to a user when the discriminative tool identifies the synthetic image as a real image. A system and a non-transitory, computer readable medium storing instructions to perform the above method are also provided.
