c++ - How to load a bitmap from file into the samples buffer -


I am trying to add text to the bitmap obtained from the DirectShow filter. First of all I tried to use gdiplus, but that was not working so now I just call a net program that connects to bitmap.

The problem is that I do not know how to reload the bitmap from a file into buffer samples in a direct save.

Here is my code: 

  Bitmap BMP (640, 480, 2560, 1379773, Newbuffer); // save clsid pngClsid; GetEncoderClsid (L "image / PNG", & amp; pngClsid); WCHAR * file = L "D: \\ temp \\ sample.bmp"; Bmp.Save (file, & amp; pngClsid, NULL); Std :: string command ("D: \\ yourcontrol \\ bitmapDraw.exe D: \\ temp \\ sample.bmp \" test text \ "D: \\ yourcontrol \\ out.bmp"); // Heripal system (command.c_str ()); // Load Bitmap BMP 2 (D: \\ Your Control \\ Out.bmp);

How do I forward bitmap from file to sample?

Media samples are a part of the agreement between filters on specific pin connections. You usually do not load media samples until you run any filters and you are distributing data to your output pin.

In the latter case you have media types of media, you allocate and start the media specimens, and your work is straightforward: to load the image, the data in your media sample buffer, By confirming the code> memcpy , the media type matches the image format (or you otherwise have the responsibility to change). Once you give media samples, you usually do this (the closest sample to these Windows SDKs).

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...

multithreading - Reorderings in java memory model -

Read again, find out I do not understand a sentence: We consider only the variables here that are readable and writeable as a nuclear unit - That is, there is no bit field, unrecognized access , or larger than the word sizes available on any platform. is. Anyone can explain the above cases on which the words are bold. On some architectures, the processor can access multiple storage in one command: BIT FIELD: Setting up some pieces of memory; It is usually implemented with different access to reading and writing, using read-write-write. Unwritten Access: On some CPU architectures, the processor impedes the barriers to the addresses you can use, when you access multibeat values, especially if you exceed the word limitations. Most modern processors Does not have this problem because they can perform multiple readsets to cover the required address range; If you read from 0x01 to 0x05, then it is read 0x01-0x04 and a 0x05. If you have to write there, then it is complicated;...

OK, so I remove an orange from the array list, break it, but I still get the outbound I am a little confused, someone can help me, I have tried to separate the problem, but I still can not understand it.
