Schema

[Core Function] Kling Image Expansion is an outpainting model. [Strengths] It intelligently extends the borders of an image (horizontal, vertical, or asymmetric) while matching the original style and context. [Best For] Highly recommended for: changing aspect ratios, extending landscapes, and filling out cropped photos. [Limitations] Do NOT use this model for inpainting or style transfer. [Routing] Use this specifically when the user asks to 'expand', 'extend', or 'uncrop' an image.
