如何使用「照片转素描（铅笔画 / 线稿）」？How do I use the Photo to Sketch (Pencil Drawing & Line Art)?
选择或拖入一张照片，默认生成铅笔素描效果。切换“彩铅”“线稿”“炭笔”风格，拖动滑块调整笔触粗细和浓淡；勾选“显示原图”可以对比。满意后点“下载素描图”。Choose or drop a photo to get a pencil sketch. Switch to Coloured pencil, Line art or Charcoal and adjust stroke and darkness; tick “Show original” to compare, then download.
什么样的照片转素描效果最好？Which photos work best?
光线均匀、主体清晰、背景简洁的照片效果最好，例如人像、建筑、宠物特写。背景太杂乱时，可以先用“AI 智能抠图”去掉背景再转素描。Evenly lit photos with a clear subject and simple background — portraits, buildings, pet close-ups. For busy backgrounds, remove the background first with the AI Background Remover.
线稿可以用来描画或涂色吗？Can I use the line art for tracing or colouring?
可以。选择“线稿”风格，把“细节”调低、“浓淡”调高，得到干净的黑色线条，打印出来可以描画或给孩子涂色。Yes. Choose Line art, lower Detail and raise Darkness for clean black lines that print well for tracing or colouring.
导出的图片分辨率是多少？What resolution is exported?
与原图相同（超大图片会限制在 2400 像素以内以保证速度），可以直接打印或用作头像。Same as the original (very large images are capped at 2400 px for speed), fine for printing or avatars.
