Just use XPutImage(display, xid, gc, image, src_x, src_y, dst_x, dst_y,
	width, height);

i.e.

    canvas = xv_create(frame, CANVAS,
        CANVAS_REPAINT_PROC,    canvas_repaint,
        CANVAS_X_PAINT_WINDOW,  TRUE,
...

canvas_repaint(canvas, pw, display, xid, xrects)
Canvas          canvas;
Xv_Window       pw;
Display         *display;
Window          xid;
Xv_xrectlist    *xrects;
{

...

    XPutImage(display, xid, gc, image,
        0, 0, x, y, w, h);
...
