javascript - Canvas setLineDash and lineDashOffset NOT resetting in iOS/Safari? -


यहाँ बेला देखें:

मेरे पीसी पर, 

  ctx.lineWidth = 20; ctx.setLineDash ([20,30]); ctx.lineDashOffset = 10; ctx.beginPath (); ctx.moveTo (150,150); ctx.lineTo (240,240); ctx.lineTo (180,40); ctx.stroke (); Ctx.closePath ()

वांछित डैश / ऑफ़सेट

अब 

  ctx के साथ लाइनों का पहला सेट देता है। setLineDash ([0,0]); कमांड के अगले बैच में ctx.lineDashOffset = 0

: 

  ctx.beginPath (); // रीसेट करता है डैश ... IOS सफारी को छोड़कर ऐसा लगता है ... ctx.setLineDash ([0,0]); ctx.lineDashOffset = 0; ctx.moveTo (0300); ctx.lineTo (0,250); ctx.lineTo (100,400); ctx.lineTo (200,300); ctx.stroke (); Ctx.closePath ()

लाइनों के पहले सेट के बाद कोई डैश गुण रीसेट करने लगता है। फिर से ठोस लाइनें प्राप्त करें

एक iPad2 चलाने वाले सफारी पर ... ऐसा लगता है कि पूरी तरह से नजरअंदाज कर दिया जाता है, लाइनें धराशायी रहती हैं। ऐसा क्यों है? इसके अलावा, क्या लाइन डैश ठीक से रीसेट करने के लिए कुछ अन्य विधि है ...?

इस संकेतन का उपयोग करें, यह सभी ब्राउज़रों में काम करेगा जो setLineDash का समर्थन करता है 

  ctx.setLineDash ([]);

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...

I would like to add color code support in my config.yml . How do I add translateAlternateColorCode to my code correctly? Public boolean on command (CommandSender sender, command CMD, string label, string [] args) {player player = (player) sender; If (cmd.getName () .all ignored cas ("member") {player.sendMessage (getConfig (). GetString ("member text")); } You can simply use translateAltranateColorCodes . Here's an example: string nonColoredText = getConfig (). GetString ("member text"); // "member text" string get colored text = raw string. Translate Altinetic Color Code ('& amp;', nonColoredText); // Edit the colors code Any of the above text which is & amp; starts with the correct color code, for example, if & amp; A was in config, it would convert it to green color or ChatColor.GREEN , which will show the message in green, it also works with other characters such as you color If you want to use...
