[java-dev] Re: Jitter in mxj

Hi,

As an update - here's the code. I get the dimensions 307200 (=240*320*4) for the return of copyMatrixToArray, but it doesn't seem to work right. If I try printing out a value of my new array, I always get -1. I've tried both int and float[] arrays.

Any ideas?

Andrew.
