My first lesson of JS is to make jit.grab component and to output this through a js object.

The output matrix is pretty weird; it seems like it would be a 4 char @dim 1 1, although the jit.fpsgui tells me that it's a 320 240 matrix…

var cam = new JitterObject("jit.qt.grab");

var output = new JitterMatrix(4,"char",320,240);

    cam.matrixcalc(output/*null*/,output);

    outlet(0,"jit_matrix",output.name);

I don't understand…
here's my js script: 

function bang()
{
	cam.matrixcalc(output/*null*/,output);
	outlet(0,"jit_matrix",output.name);
}

silly-question-about-output-a-jitter-matrix

you've set both cam.dim and output.dim to 320,240 . why would you assume the outputdim is 1,1?

Because that's the content of my pwindow…one single cell…
