9.  Graphics Functions  

(clear-area window x y width height exposures?)

See XClearArea.

(copy-area src-drawable gcontext src-x src-y width height dst-drawable dst-x dst-y)

See XCopyArea.

(copy-plane src-drawable gcontext plane src-x src-y width height dst-drawable dst-x dst-y)

See XCopyPlane. plane is an integer. An error is signaled unless exactly one bit is set in plane.

(draw-point drawable gcontext x y)

See XDrawPoint.

(draw-points drawable gcontext vector-of-points relative?)

See XDrawPoints. vector-of-points is a vector of pairs consisting of two integers (the x and y coordinates). If relative? is #t, CoordModePrevious is passed to XDrawPoints, otherwise CoordModeOrigin is used.

(draw-line drawable gcontext x1 y1 x2 y2)

See XDrawLine.

(draw-lines drawable gcontext vector-of-points relative?)

See XDrawLines. See draw-points above.

(draw-segments drawable gcontext vector-of-points)

See XDrawSegments. vector-of-points is a vector of lists of four integers (x1, y1, x2, and y2).

(draw-rectangle drawable gcontext x y width height)

See XDrawRectangle.

(fill-rectangle drawable gcontext x y width height)

See XFillRectangle.

(draw-rectangles drawable gcontext vector-of-rectangles)

See XDrawRectangles. vector-of-rectangles is a vector of lists of four integers (x, y, width, and height of each rectangle).

(fill-rectangles drawable gcontext vector-of-rectangles)

See XFillRectangles. See draw-rectangles above.

(draw-arc drawable gcontext x y width height angle1 angle2)

See XDrawArc.

(fill-arc drawable gcontext x y width height angle1 angle2)

See XFillArc.

(draw-arcs drawable gcontext vector-of-data)

See XDrawArcs. vector-of-data is a vector of lists of six integers (x, y, width, height, angle1, and angle2).

(fill-arcs drawable gcontext vector-of-data)

See XFillArcs. See draw-arcs above.

(fill-polygon drawable gcontext vector-of-points relative? shape)

See XFillPolygon. See draw-points above. shape is a symbol (complex, non-convex, or convex).
