ColorReplace
ColorReplace
ColorReplace[image,color]
在 image 中查找像素值与 color 相似的区域，并将其用透明像素替换.
ColorReplace[image,colorreplacement]
使用指定的 replacement 颜色替换所有像素.
ColorReplace[image,colorreplacement,d]
替换所有值与 color 的距离在 d 以内的像素.
ColorReplace[image,{color1replacement1,…},{d1,…}]
替换多种颜色.
更多信息
- ColorReplace 适用于任意二维和三维图像.
- ColorReplace[image,color] 等价于 ColorReplace[image,color,0.1].
