我正在使用PIL来调整我的图像大小,我的情况是扩大原始图像.
我对使用`resample = ANTIALIAS'的算法感到困惑.
根据下面的文件,ANTIALIAS在缩小规模时似乎是最好的.我想知道在哪种情况下可以BICUBIC获胜?(我的一些测试案例显示双三次更好的选择)
An optional resampling filter.
This can be one of NEAREST (use nearest neighbour),
BILINEAR (linear interpolation in a 2x2 environment),
BICUBIC (cubic spline interpolation in a 4x4 environment),
or ANTIALIAS (a high-quality downsampling filter).
If omitted, or if the image has mode “1” or “P”, it is set NEAREST.

我也感到困惑了linear interpolation in a 2x2 environment,并cubic spline interpolation in a 4x4 environment在文档中.这是什么意思?
谢谢.
