使用流程

Leg Length makes a restrained change to two clearly separated legs you can clearly see, and leaves the rest of the photo exactly as you shot it. It locates each person by their face, shoulders and hips, then separates two clearly separated legs from the background, hair, skin and clothing before anything moves. The adjustment eases off to nothing at every edge of that area, and nearby background is filled in behind the new outline so no gaps appear. The face and every pixel outside the adjusted area are copied straight into a lossless PNG. In a group photo you pick who to change, or switch on "Apply to everyone" in Settings. Anyone standing too close for their neighbour to stay untouched is left alone rather than guessed at. If the photo is unclear, cut off, transparent or ambiguous, it stops instead of guessing.

处理中

腿长使用 AI 动作。任何单独的余量都会在该效果开始处理之前显示。

最适合

sharp, opaque, front-facing photos with a clear face, both shoulders, hips, knees, ankles and shoes visible head to toe, straight legs held apart, and clean background beside and below both feet — including group photos where each person has clear space around them.

不太适合: people packed shoulder to shoulder with no gap between them, side or seated poses, seated or crossed legs, feet cut off at the frame edge, long skirts or coats that hide the legs, cluttered floors, transparent cutouts, motion blur, and bodies touching the image edge.

使用方法腿长

  • 适度调整腿长,无需重新生成面部身份特征、衣物纹理、鞋子或整张人像。
  • 拉长两个独立腿部区域,同时保持面部、躯干、髋部、双臂、大腿上部和远处背景与原图完全一致。
  • 调整强度,在固定安全上限内选择轻微或更明显的腿长预览效果。

关于 腿长 效果的常见问题与解答

腿长调整会拉伸我的鞋子或上半身吗?
垂直拉伸在每个已验证的脚踝处结束,随后现有鞋子像素作为整体在局部区域内向下平移。上半身及两个腿部区域外的像素保持精确不变;鞋子移动时,边缘少量抗锯齿像素可能会被重新采样。
为什么腿长调整需要地面空间和分开的双腿?
向下移动两只鞋需要经过验证的源背景,以便在鞋子两侧和下方重新分配像素。如果双腿相贴、鞋子被裁切,或其他物体占据该空间,工具就无法分离出两个安全区域,会停止处理而不是扭曲错误的像素。
