var master = document.getElementById('master');
var masterctx = master.getContext('2d');
var pid = document.getElementById('pid').getContext('2d');
var di = document.getElementById('di').getContext('2d');

var idfull = masterctx.getImageData(0, 0, 100, 100);
var idhalf = masterctx.getImageData(25,0,75,100);
Tests:

  • DrawImage whole master into di canvas

     
    di.drawImage(master,0,0);

  • PutImageData whole master into pid canvas

     
    pid.putImageData(idfull,0,0);

  • DrawImage half master into di canvas

     
    di.drawImage(master,25,0,50,100,25,0,50,100);

  • PutImageData half master into pid canvas

     
    pid.putImageData(idhalf,25,0);
