Just iterate a write iterator over the size of the image to fill the layer 
with pixels.

KisRectIterator it = dev->createRectIterator(0, 0, img->widht(), 
img->height(), true);

Reading always works, so if you just need to read pixels from the size of a 
full image, just create the iterator to read.
