Hello, I need a tipp for drawing an oval around a dynamic textfield with variable line numbers and variable width? Perhaps, someone can point me to a good tutorial dealing with such geometry questions. The drawOval methods I am using have width and height as parameters, but of course I can't use width and height of the textfield without a padding. How can I calculate an i appropriate padding? The drawOval methods:
public function drawOval_Old(x:Number, y:Number, width:Number, height:Number):Void { movieClip.lineStyle(lw, lc, la); movieClip.moveTo(x,y+height/2); movieClip.curveTo(x,y,x+width/2, y); movieClip.curveTo(x+width,y,x+width, y+height/2); movieClip.curveTo(x+width,y+height, x+width/2, y+height); movieClip.curveTo(x,y+height, x, y+height/2); } public function drawOval(x:Number, y:Number, width:Number, height:Number):Void { x+=width/2; y+=height/2; width/=2; height/=2; var j:Number = width * 0.70711; var n:Number = height * 0.70711; var i:Number = j - (height - n) * width/height; var m:Number = n - (width - j) * height/width; movieClip.lineStyle(lw, lc, la); movieClip.moveTo(x+width, y); movieClip.curveTo(x+width, y-m, x+j, y-n); movieClip.curveTo(x+i, y-height, x, y-height); movieClip.curveTo(x-i, y-height, x-j, y-n); movieClip.curveTo(x-width, y-m, x-width, y); movieClip.curveTo(x-width, y+m, x-j, y+n); movieClip.curveTo(x-i, y+height, x, y+height); movieClip.curveTo(x+i, y+height, x+j, y+n); movieClip.curveTo(x+width, y+m, x+width, y); } Thanks, Matthias _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
