纯白、纯色背景效果最佳;背景与主体颜色相近时可降低容差避免误删;点击图片上任意背景像素可手动指定背景色,多次调整直到满意。
Solid white or solid-color backgrounds work best. If the background is close to the subject, lower the tolerance to avoid over-removal. Click any background pixel to set the color manually, and adjust until it looks right.
本工具基于颜色去除,适合纯色或接近纯色的背景;渐变、复杂背景建议先用其它工具压平或换纯色背景。This tool removes by color, so solid or near-solid backgrounds work well. For gradients or complex scenes, flatten the background first.
适当提高容差让去除范围更平滑,或导出后在图片软件里对边缘做轻微羽化。Slightly raise the tolerance for smoother removal, or feather edges lightly in an image editor after export.
