ImageView

ImageView view = image.view();

//Assign a square.
view[4..40][5..50] = new Color("red");

//Reduce a view.
view = view[10..view.extend.height-10][20..view.extend.width-20];

//Assign a single row.
view[30] = new Color("blue");
//Or a column.
view[][30] = new Color("blue");
//And induvidual pixels.
view[3][5] = new Color("green");

//We can also use foreach.
foreach ( row; view )
{
    //This is executed in parallel.
    foreach ( ref pixel; row )
        pixel = new Color("black");
}
