VERSION: X11R2 SYNOPSIS: filling arcs with XFillArc(s) and arc_mode==ARCPIESLICE produces funny results when angle2 is > 180 degrees. REPEAT-BY: XFillArc(dpy, mainWindow, gc, x, y, w, h, 135*64, 250*64); FIX: (has only been tested on Siemens machines) after computing the points for the polygon, miPolyFillArc passes them to FillPolygon, with Convex shape. The Pie is only Convex, if angle2 <= 180 degrees. .... pPts[0].y = parcs[i].y + parcs[i].height/2; if (parcs[i].angle2 < (FULLCIRCLE/2)) (*pGC->FillPolygon)(pDraw, pGC, Convex, CoordModeOrigin, cpt + 1, pPts); else (*pGC->FillPolygon)(pDraw, pGC, Nonconvex, CoordModeOrigin, cpt + 1, pPts); .... by the way: shouldn't we move the Xfree out of the if statement ? improvement, comments welcome -- no flames please !
