Oh, that, ah, well, no 
I'm using this code for WebJCS (JavaScript):
PHP Code:
var w = parallaxC.offsetWidth;
var h = parallaxC.offsetHeight;
var scrollX = LayerDiv.scrollLeft;
var scrollY = LayerDiv.scrollTop;
if(h < 5) return;
var scrollXoffset = Math.round((LayerDiv.offsetWidth)/2-w/2);
var scrollYoffset = Math.round((LayerDiv.offsetHeight)/2-h/2);
var drawn = 0;
var srcpos=null;
for(var l = 7; l >= 0; l--) {
for(var ii=Math.floor((scrollX*layerSpeed[l][0]+scrollXoffset)/32)*32; ii <= Math.ceil((scrollX*layerSpeed[l][0]+scrollXoffset)/32)*32-(scrollX*layerSpeed[l][0]+scrollXoffset)+Math.floor((w)/32)*32+Math.floor((scrollX*layerSpeed[l][0]+scrollXoffset)/32)*32+32; ii+=32) {
for(var jj=Math.floor((scrollY*layerSpeed[l][1]+scrollYoffset)/32)*32; jj <= Math.ceil((scrollY*layerSpeed[l][1]+scrollYoffset)/32)*32-(scrollY*layerSpeed[l][1]+scrollYoffset)+Math.floor((h)/32)*32+Math.floor((scrollY*layerSpeed[l][1]+scrollYoffset)/32)*32+32; jj+=32) {
// Check for tiling layers etc...
// Using this drawing function
srcpos = idXY(tileData[l][ii/32][jj/32] % 1024, 10);
pcc.drawImage(tilesetImage, srcpos[0]*32, srcpos[1]*32, 32, 32, ii-(scrollX*layerSpeed[l][0]+scrollXoffset), jj-(scrollY*layerSpeed[l][1]+scrollYoffset), 32, 32);
It works, but it's not the same

Still, the wanted result is this:
