Ok, thanks, it works now. Actually I have huge problem with small sprite that somehow gets stretched as background and have no idea why it appears.

Could you give me patch at least ? Is it ok just to check for NULL?

Window / sf::RenderWindow crash

I have ATI card, winXP, 2 monitors. So in my code:

Code: [Select]

       sf::WindowSettings st;
        st.AntialiasingLevel = 8;  // Make smooth drawing
        delete(m_pSfmlView);
        m_pSfmlView = new sf::RenderWindow(GetSafeHwnd(), st);

I have sporadic crash here:

Code: [Select]

void WindowImplWin32::CreateContext(const VideoMode& Mode, WindowSettings& Params)
{
...
   bool  IsValid = wglChoosePixelFormatARB(myDeviceContext, IntAttributes, FloatAttributes, sizeof(Formats) / sizeof(*Formats), Formats, &NbFormats) != 0;

..
}

I can see that wglChoosePixelFormatARB is NULL.
looks like call

Code: [Select]

       // Get the wglChoosePixelFormatARB function (it is an extension)
        PFNWGLCHOOSEPIXELFORMATARBPROC wglChoosePixelFormatARB = reinterpret_cast<PFNWGLCHOOSEPIXELFORMATARBPROC>(wglGetProcAddress("wglChoosePixelFormatARB"));

 failed. I have no idea why.

Graphics / ghost on background

« on: March 10, 2010, 02:52:26 am »

I have MFC window where I draw background - sprite. And after I draw small items, lest call em targets. It works ok, but sporadically I can see target scaled to size of window on a top of background and regular size targets on it. I simplified my code to min but still cant find how it is possible  ? Any suggestions where this scaled target coming from?

Graphics / Fill shape with pattern

« on: March 04, 2010, 04:06:26 pm »

Interesting, so I can fill shape with color I like and employ blender somehow to make pattern ? Could anyone give me short sample for this color blending  ?
Thanks

Is there any way to fill shape not just color but specific pattern or bitmap ?
Thanks

Graphics / GDI primitives vs SFML primitives

« on: March 02, 2010, 09:04:33 pm »

It is not friendly and I dont have time to implement own set of classes on top of it. But GDI is also not good. It it is easy to make a leak, no antializing, no transparency. Yes, you can use GDI+ which is cool, but it has no hardware acceleration. So if SFML at least not worst then GDI, it is still acceptable. I'll make this comparison today , something around 10000 shapes

Until you are not starving, then yes, but in graphics you are always starving I have to support reasonable frame rate in map and have responsible GUI. And better performance is my best friend.

If SFML is not better (which is faster IMHO) then GDI what the reason to use it ?

Just curious if anybody check performance GDI vs SFML, what is faster , lines, ellipses, bitmap drawing ? sure I can write test APP to do so, but probably it was already done ?
