we drawing arc in java application using drawarc method provided java api.
drawarc(int x, int y, int width, int height, int startangle, int arcangle)
i searching similar method in html couldn't succed. there
drawarc(x, y, radius, startangle, arcangle)
method there.
is there equivalent method in html in java. if not please guide me alternate method can succeed.
there exists experimental ellipse
function in browsers, can use geometrical transformation (a vertical/horizontal scaling) obtain effect. if original java call was:
drawarc(x, y, width, height, startangle, arcangle)
it realized with:
if (width>height) { gctx.settransform(width/(float)height,0,0,1,0,0) radius = height } else { gctx.settransform (1,0,0,height/(float)width,0,0) radius = width } gctx.drawarc(x, y, radius, startangle, arcangle)
