问题
Photoshop has that great: BiCube Shaper option for resizing.
However I cannot find an equivalent.
I've seen various code using GD that used imagecopyresampled and custom unsharp mask, but no where near the quality I am expecting.
Any help?

If all you've tried is GD, you might want to give some of the ImageMagick sampling filters a shot. Here's a page that examines them along with the PhotoShop ones:
