Render huge image in Qt
<p>I have to render a huge image (e.g. 30.000 x 30.000 pixels) in a Qt based app.</p>

<p>I can do this via OpenGL, but I load it as a single texture. Therefore, I am limited by my graphics card max texture size (in this case, 16.368 pixels). I need to implement something like tiling or similar, while maintaining a good rendering performance.</p>

<p>Is there any example to accomplish this, preferably with good Qt integration? (not necessarily OpenGL).
Or is there any other starting point?</p>

<p>Thank you</p>
