i have image data in a 2D array that i'd like to change the size of. currently, i'm just doing a dirty sampled scaling that i came up with. this works, but can only do a 2x resize. dst[::2,::2] = src dst[1::2,::2] = src dst[:,1::2] = dst[:,::2] this isn't too bad, but it's definitely one of my bottlenecks, can the code to do this be sped through some ingenious use of numeric? i'm also trying to figure out a clean, fast way to do bilinear scaling on my data. it seems like there would be something in numeric to do linear resampling, but i haven't figured it out. i'd like to be able to resample stuff like audio data as well as just image data. thanks for any pointers into this.
