On May 23, 4:53 am,
in general you don't use byte[] or the bynary content of a file directly in the
client side, unless you are making something *really special* like implementing
image filters using html canvas or somthing like that. What are you trying to
do or better, why do you have to read a file into a
Well, it is a binary file with point/spline-data. I need to construct

If the goal is to read a file and perform computations on the data,
then that process belongs on the server, where it can be done in Java,
and on a machine that has significantly more horsepower. Process the

processed data over to
so I guess it is an array of points and you wish to represent them as byte[].
In the client side, I think byte[], int[] or double[] are the same internally,

Also it uses JavaScript typed arrays (new FLoat32Array) for accssing the array
