  • Optimizing / simplifying a path

    - by user146780
    Say I have a path with 150 nodes / verticies. How could I simplify if so that for example a straight line with 3 verticies, would remove the middle one since it does nothing to add to the path. Also how could I avoid destroying sharp corners? And how could I remove tiny variations and have smooth curves remaining. Thanks

  • May be an IE z-index bug?

    - by baikaishiuc
    Below is my code. when open the page in ie browser, then select the text in div, the text will be replaced by some shadow quad blank . If you delete a line z-index:0, in css class test1, the ie will perform correctly. In my project , the z-index must be set greater than zero, so I couldn't delete the line. I found a solution is to set bg_img.filter = "" when pannel.z-index greater than 0, then ie will also working good. But unfortunately, the bg_img.filter.alpha must be set, too. So how could I do? test .test1 { position:absolute; background:#ffffff; left:20px; top:20px; border:1px solid; width:198px; height:500px; filter: progid:DXImageTransform.Microsoft.Shadow(color="#999999", Direction=135, Strength=5); z-index:0; } </style> <script> function init () { var pannel = document.createElement ('div'); var bg_img = document.createElement ('div'); var head = document.createElement ('div'); pannel.setAttribute('class', 'test1'); pannel.setAttribute('className', 'test1'); bg_img.style.cssText = "position:relative;left:0px;top:0px;" + "width:198px;" + "height:500px;" + "filter:alpha(opacity=100);"; head.style.cssText = "position:absolute;" + "left:0px;" + "top:0px;" + "width:180px;" + "height:20px;"; document.body.appendChild (pannel); pannel.appendChild(bg_img); pannel.appendChild(head); head.innerHTML = "<div>yusutechasdf</div><div>innerhtml</div>" } </script>

    - by sqwerty
    MethodInfo mi = typeof(NotifyIcon).GetMethod("ShowContextMenu", BindingFlags.Instance | BindingFlags.NonPublic); mi.Invoke(notify, null); This throws the following exception: {"Exception has been thrown by the target of an invocation."} With the following inner exception: "Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on." If I comment out a line of code that sets the images for the context menu entries then it stops throwing the exception. Any ideas?
