Resizing an image with transparency

Hy guys ! I have a little problem and I can not find answers. When I try to resize a picture with transparency I get a border between transparency and the other color. On white you can see the border really clear on other colors not so much, but is there.

If I use RESIZE_NEAREST_NEIGHBOR the transparent image looks okay, but the quality of other pictures is poor. If I use the other ones I end up with a picture with a border between transparency and color. Do you have any idea ? Any advices ? Thank you !
