c# - WPF: How do I prevent tearing with WriteableBitmap? -

-

I am using images to display which I process myself at approximately 20 frames per second.

This question ()
and this question ()
indicates that the best way to do this is to use a WriteableBitmap

WriteableBitmap indicates that the call to write WritePixels () will be due to the thread rendering thread on the UI thread:

MSDN documentation:
The UI thread writes content back in the buffer. The render thread reads the contents in front buffer and copies it to video memory. The changes made in the back buffer are tracked with changing rectangular areas.

& lt; Snap />

When an update is sent to the rendering thread, the rendering thread copies the rectangles converted from backup buffers to the front buffer. The rendering system controls this exchange to prevent circumvention and to recreate artifacts, such as "torn".

I process my images on a background thread, then use Dispatcher.BeginInvoke () to call WritePixels () , To make sure that WritePixels () is called on the UI thread.

I still feel torn with writeable bitmap , and on which I am working, it looks terrible (its medical imaging app). Is there anything I can do?

After "text" itemprop = "text">

There was a lot of putting in WriteableBitmap to avoid tearing, but on some system configurations It is inevitable that this will mostly close Windows XP or Vista w / Aero (DWM).

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
