RR - Fill Rectangle Relative

RR X, Y[;]

X ; X coordinate of opposite angle for the rectangle

Y ; Y coordinate of opposite angle for the rectangle

• Coordinates are relative to the current position in user units or graphics units.

• Fill in the rectangle formed by the current position and the opposite angle specified by X and Y.

• After plotting the cursor returns to its point of origin.

• Plotting is performed whether the pen is up or down.

• When scaling has been performed, the rectangle is plotted in user units.

• Also, when scaling has been performed, the values for X and Y are real numbers.

• When there is no scaling, the rectangle is plotted in graphics units.

• When there is no scaling, the coordinate values for X and Y are integer numbers.
