I personally think that using canvas to do drawing or relatively weak, some of the complex features are not very good to achieve, but you can also try to, for example, to add a method to save the picture, define Draw.prototype.save = function () {...}, Where the Todataurl method im

accordance with AAC compression, and then write to the MP4 file, Because before this experience, so the earliest use of wince default WMV9 soft code, the result of less than 10 seconds compressed, the machine died. At first thought it was their own code did not write correctly, many attempts, basically toss for a week, and finally found that the machine memory continues to fall until all eat, Then came the clear: on the small machine, the use of soft coded compressed audio and video data, basic

This article is an example of how the go language implements a simple message board. Share to everyone for your reference. The implementation methods are as follows: Copy Code code as follows: Package Main Import ( "FMT" "IO" "Log" "Net/http" "Text/template" "Time" "Database/sql" "Github.com/ziutek/mymysql/godrv" ) Message structure Type Liuyan struct { Id int Name string Content string Time int } Show Message Time

At that time did not feel anything, look back today, feel still a little meaning, bring to everyone to identify. The first step is to implement the arrangement of the pieces, which no doubt have to use DIV+CSS. The specific code can look at the chess board of jquery (see source code). At first I wrote a class for every piece of chess, which was actually a stupid act. First, this CSS code will have redundancy. Second, in the pawn div binding list
