The next four parameters, dx, dy, dw, and dh determine the region of the canvas to blend into. (dx, dy) is the top-left corner of the region. dw and dh are the regions width and height.
The tenth parameter, blendMode, sets the effect used to blend the images' colors. The options are BLEND, DARKEST, LIGHTEST, DIFFERENCE, MULTIPLY, EXCLUSION, SCREEN, REPLACE, OVERLAY, HARD_LIGHT, SOFT_LIGHT, DODGE, BURN, ADD, or NORMAL
