• [sprite],_x[%|~],_y[%|~],_z[%|~],_c[%|~],_opacity

Description:

Draw specified sprite on selected images, considering that the sprite's last channel is the drawing's alpha.

(equivalent to shortcut command ja).

If one of the x,y,z or c argument ends with a ~, its value is expected to be
a centering ratio (in [0,1]) rather than a position.
Usual centering ratio are { 0:left-justified | 0.5:centered | 1:right-justified }.

Default values:

x=y=z=c=0 and opacity=1.
