c++ - DirectX9 Texture of arbitrary size (non 2^n) -

-

I am relatively new to DirectX and I have to work on existing C ++ DX9 application. The app monitors the camera images and displays some direct-more (i.e. 2D) content. There is an aspect ratio of 4: 3 (always) in the camera and the screen is undefined.

I want to load a texture and want to use this texture as a mask, so tracking and displaying content is done only within the masked area of ​​texture so I have a texture I would like to load, which has the same size as the camera's images.

I have completed all the steps to load texture, but when I call GetDesc () field width and The height of D3 DSURFCDUNDC is the next big power-of-2 size. I do not care that the actual memory used for texture has been optimized for the graphics card but I did not find any way to get the dimensions of the original image file on the hard disk.

Search for the possibility of loading the RAM in the computer (no graphic card is needed) without adding a new dependency to the code (and done but without success) code. Otherwise I have to use OpenCVI (which may be a good idea in terms of tracking), but for the moment I still try to avoid with OpenCV.

Thank you for your hints, Norbert

with parameters 3 and 4 < / P> 

  D3DX_DEFAULT_NONPOW2. After this, you can use  
  D3 DSURACDACC DCC; M_Sprite-> GetLevelDesc (0, & Disco);  
 
 To get the height & amp; Width

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image.

Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
