如何调整WriteableBitmap的像素大小（windows store c＃）

Question

I searched in many forums and I didn't get what I want.

My question is clear and simple : How to resize pixel of WriteableBitmap , for example from 300*300 to 500*500

Answer 1

Look at the WritableBitmapEx project. You can use it or learn how to resize your image. It is easy to do it by using WritableBitmapEx extensions methods.

// Resizes the WriteableBitmap to 200px wide and 300px high using a bilinear interpolation method
var resized = writeableBmp.Resize(200, 300, WriteableBitmapExtensions.Interpolation.Bilinear);
