创建 transparent background

Branch logic

• If the user has not provided 源图 或 object image, ask 用于 it before generating the final transparent PNG.
• If a reference image is provided, preserve the subject identity, proportions, 和 important details before changing style 或 scene.
• If the first result fails 视觉 inspection, fix the smallest broken area first instead of regenerating the whole image.
• If the first tool path fails, switch to the next listed option: SAM, Recraft.
• If the task depends on masks, text, 或 object edges, inspect those details at full size before accepting the 输出.

When not to use

• Do not use this as proof that the generated transparent PNG is factually real 或 legally approved.
• Do not use it when the user needs professional legal, medical, safety, 或 regulated-compliance judgment.

• The final asset clearly matches the requested transparent PNG.
• The main subject still reflects the original 源图 或 object image.
• Text, hands, logos, edges, 和 产品细节 are not visibly broken.
• The result is usable in the target channel 且不 another full regeneration.
